Mini-z F1 boats...

[mini-zfuel]

I read all the threads, and was wondering if anyone has picked these up, I am about to buy one of each, and race them at my duck pond right by my house... I am looking at the energizer 2500 mah nimh to use for the transmitters and charger... being the guy I am buying the boats from (rl on e b a y) wanted $19 for FOUR sanyo 2500's I figured the energizers would be a MUCH better deal... especially nedding 32 batteries for two boats!!! :eek: I also can't wait for upgrades to come out... props and a motor so far...
thoughts/ideas??? anyone got any pics of thiers etc??? would like to hear about these cool new minis...

[mini-zfuel]

wow 24 views and NO replies??? could really use the experts here help and advice on these miniz boats...
thanks

[arch2b]

one of the few thread on the f1 boats, these are such a niche market that it's going to be tuff finding others that have these and are willing to post in detail about them.

if you have any questions about parts, email the shop. shop@mini-zracer.com

do you feel the battery choice I have made will do the job?
thanks

appreciate all the help... I can't believe NOONE has these here... I have waited a week for some talk about these and NOTHING... I still don't know if I should even order them now... looking at mini infernos as well.. I do really like the half 8 site...

[arch2b]

i asked and was told that the shop DOES have the mini-z f1 boats in stock :) simply email the shop for those that are interested

I emailed them.... hopefully they have the ones I want...:)

[kurtmeyer69]

i will be buying one soon....kurt

[bithed]

..if all you are really asking is the difference between batteries i would go SANYO over ENERGIZER...much punch for your buck...just my opinion...

...the boats have been out for a while here but as Arch says they are VERY niche...motors are out too here...I have honestly never seen one...thats no surprise because i dont go near water ;)

...I picked up some posters from my supplier though...pretty cool...

...off-topic but the h8 is pretty cool ;)

[TITANIUM]

i want to see video!
anyone know a link to one or can someone post one?

[G'ZOX]

theres a video of the boats in action on the Kyosho site....

I soo want one of these. I don't live near anykind of water whatsoever (besides the ocean) but I'll bet I can find a park with a pond somewhere around where I live..

I've never owned an R/C boat before but it just looks like they could be pretty cool.

and BTW I use Energizer rechargeables on my MR-02 racer and they seem fine to me.
I need to get the rapid charger though because the one that I bought with the set takes like 2 days to charge four AA's.. :(

[T-Bolt]

I have a kokam 145 pack waiting to go in one.

Bad Boat!

First impression
Took a Mini-Z Formula Boat out for a test run, my first impression was “this is fun but a little slow” and even before the battery ran out my next thought was “ok, I’m board” have to fix this.
http://lbspd.com/v-web/gallery/albums/album67/b1.sized.jpg
My fix
Custom 31 gage BSRT balanced armature with diamond trued comm, high temp auto aligning end bell, ceramic magnets, special brushes.
7.4 volt, 600 mAh Lithium-poly battery pack (only weighing 8 grams more than the stock pack)
http://lbspd.com/v-web/gallery/albums/album67/b3.jpg
Dry run
Turn on, test steering “ok works.” Tentatively try throttle “ok that works too.” Reverse “good.” Full throttle “nice” stop and try again “hm what’s up it seams to be stuck.” Free shaft from melted plastic “ok, important safety tip only run in water to keep shaft from melting plastic.”

In the pond
Put in water and pull throttle, boat takes off hopping like a dolphin “wow” give it full throttle and it jumps ahead nearly hydroplaning, then stops “woops.” Look at water and wonder if you feel like swimming “not” but fortunately the wind is blowing so it’s just a matter of time before it gets blown to the shore.

Conclusion
Yep, it’s a Mini-Z you put a super hot modified motor in and you will definitely fry the FETs. No problem aside from one FET being on the top and the other on the bottom of the CB, nothing a 2x2 stack won’t cure.

[cj peaches]

hey im new to this site... im planing on gettin one of these boats they look awesome... but i heard they are slow.. they have brought a new motor out havent they... just wondering wat batteries will be best for these boats goes ive heard that the stock ones dont last to long....

[LBRC]

Kyosho does have a modified motor out.

One problem with replacing the batteries is weight and balance, you could use a 5 cell pack made out of the Kan 180 NiMH cells but it would weigh about 5 grams more. For lithium’s I would recommend two E-Tec 210’s the pack would fit nicely and weigh less. I only put the 600 mAh pack in because of the high current motor I’m using to fry the stock FETs :rolleyes: .

Using a good hobby grade peak charger with the stock battery pack and motor actually gives you a good deal of run time. Depending on where you are driving it the boat is not all that slow. For example in a 20 foot pool or pond it’s more than fast enough especially with the Kyosho modified motor.

The pond I’m using is approx. 150 feet across so there is plenty of room for more speed, but to be practical if it would be much easier and cheaper just to get a bigger boat. But if you are like me and want your toys as small and fast as possible, it’s not exactly cheap but defiantly can be done. LoL just add the stacked FETs first it will save you a swim or long wait, or have a stock boat on hand to push you to the shore.

[T-Bolt]

What about a kokam 145 pack?

[LBRC]

What about a kokam 145 pack?
A two cell 7.4 volt Kokam 145 pack would work but it wouldn't be much of an improvement if any at all. The added 1.4 volts and its slight speed boost will also cause the battery to drain faster, so basically with a 145 LiPo pack the boat will go a little faster but the run time won’t be better despite the slight weight saving so it doesn’t seem worth the effort, especially since both the Worley 170’s and E-Tec 210’s are approximately the same size and price, much more bang for your buck.

A 2 parallel 2 series pack made out of E-Tec 210’s would give you 7.4 volts and 410 mAh for nice long run times with the stock motor or at least decent times with a modified one.

[cj peaches]

would a energizer 9 volt battery work any good.... would ot be to heavy or what??

[LBRC]

Too much voltage, and way-way too little current.

[cj peaches]

Too much voltage, and way-way too little current.
ok then what about doing what the mini-z cars are and putting 4 AAA batteries in it??? and also does anyone know if u can add mah together or is it just volts that can be added up??? would a 7.2 volt battery be able to work or is it to powerfull???... :confused:

[LBRC]

ok then what about doing what the mini-z cars are and putting 4 AAA batteries in it???

Well take 4 AAA’s (4.8 volts) and try to stick them in your boat to see what the problem might be and why the stock pack uses five 1/3 AAA cells.

and also does anyone know if u can add mah together or is it just volts that can be added up???

Time to do some reading on batteries and basic electronics.

Two cells in series, that’s + to – just like in a flashlight, doubles the voltage but the current and consequently mAh (milliamps delivered per hour) stays the same. But two cells in parallel (+ to + and – to –) doubles the current and therefore the mAh but the voltage remains the same.

would a 7.2 volt battery be able to work or is it to powerfull???...

If you take a look you will notice that the above boat is running on 7.4 volt lithiums so 7.2 volts would indeed work however any time you increase the voltage and current from a hot motor or even a stock motor that has the propeller caught in weeds or somthing like them you increase the chance of burning up the FETs.

[dean]

Looks like the mod motor is finally released so I just ordered my boat and mod motor and prop set. I was waiting patiently for the motor before ordering the boat.
LBRC looks like you got it all together with a nice set-up. Thanks for sharing that very helpful info!
I bought a 12 x 20 pool liner i will be filling with 3 inches of water.
I will try to post a video. I wonder if a scale water course will enhance performance. I figure 25 x 25 must be awesome.

[cj peaches]

hey im just wonder with the e-tec batteries can anyone display a pic of the way they have put it in the boat cause the way ive done it doesnt seem right.........thanx
:D

[dean]

Has not yet arrived ,was wondering does it come with a trailer hitch for the overland? ... or what have you guys done to have a hitch. - thx!

[HammerZ]

I beleve it has the hitch with it that attaches to the OL motor clip.

[dean]

Now I really can not wait for it to arrive. :eek:

[cj peaches]

Now I really can not wait for it to arrive. :eek:
yeah it has a hitch for it but has anyine tryed puttin the e-tec battery in or wat??

[dean]

I may try a new battery soon,not yet.I'm still testing.

I may be doing something wrong but I went out for a test on my new boat and wasnt impressed with stock speed.
So I put in the Kyosho mod motor and installed a prop from the optional prop set. I used the prop that gave the highest speed / lowest run time.
The boat was as fast as you dream it could be .. but for all of 20 seconds. :mad:
I just put on the slowest prop and will test today for speed / run time. Some times with mod motors they need lower gears to maximize output.
Stay tuned.

[machine]

So far i'm not all the impressed. :(

the looks are killer but the boat itself is still kinda gimmicky to me. I've peaked the stock battery cycled the stock batteries a few times and saw good improved run times and overall power, so long as you don't use the stock trailer charger. But the price still is the biggest killer for me. Mind you i do like the remote and PCB board.

I agree I got one of these back in the summer I have a 1 acre pond the boat did not peform like I had expected its nice to look at but not much for performance.

[ruf]

I haven't run mine yet. I have the Aquaspeed motor, the trim tabs and prop set. Really busy this month so I probably won't get a chance to play with it until next weekend or Thanksgiving.

The BET band board looks like an AD band board with a couple of FETs depopulated. SWEET! I need to get caught up on my reading for these little buggers.

[Allen1]

I am going to order a aquaspeed I was waiting for feedback from those whom already have the upgrades before I get one. From what I can see most seem to like the upgrade.

[ruf]

Allen1 - if you need anything, feel free to email me a contact@reflexracing.net

[dean]

Machine, I will soon post a video, i'm now impressed with it.
I will try to video it. To see if we are comparing the same preformance.

The mod motor with low pitch (like running a low gear) really let the motor do its job!
RPM's were up and the boat buzzed all over, was great.
Although I didnt stopwatch it , I will on my next run. Its much better run time now. The boat is advertised at 5 minutes run time for a 3 minute charge using a stock motor. The mod seems to be aroung 2 right now,but I still have more tweeking to do and hope to get 3 minutes at a fast raceable pace..
I have owned and still own other full size hobby R/C boats. The run time on any r/c boat has always been far less run time than the same motor and battery set into a land vehicle ,SO WITH THAT IN MIND , I'm impressed. :p

Stay Tuned - 'Same BAT time .. same BAT channel

[GiantScale]

Iv toyed around with some micro boats. One of them is a cut down turtle hull now 10" long with a speed 400 on 8 AA cells. It barely floated. But when it stopped cavitating and got on plane, watch out! Totally nuts

How long are these? Wonder if a mamba would wake it up? :p

To bad thay dont sell just the beautiful hulls. If anyone wants to sell a fried one. Let me know. I wonder if you could somehow make it a hydro instead?

[GiantScale]

Forgot to mention.. You guys might want to try sanding the bottom with 400 grit and sharpen trailing edges and props.

[dean]

I am actually planning on waxing my hull next time out. ( Probably tommorow.) :D

[GiantScale]

Take a piece of lexan and sand a small spot. Then wax a small spot if you want. Wet the area and run your finger over it. Youl find the rough area will break surface tension and let your finger slide more easy. Same applies for boats. Most record breaking boats have 400 running surfaces.

Think of it as millions of small steps. Like on cats and the new monos. And fish scales.

[dean]

That is something that I never knew.
I figured like that surfboards wax up, then i was even thinking of RainX for windshields,thought beading water was the way to go.does it matter to sand front to rear?
Do 1/10th scale R/C boaters find 400 helps on model boats? just wondering, also have you sanded your miniZ boat? :rolleyes:

[GiantScale]

Yeah. It didnt sound right when I was first told about the rough surfaces. But after reading many threads from VERY experienced boaters on rcboat.com running all sorts of nitro boats I tried it. It was not easy to remove the nice finish from my 42"seaducer gas boat. But GPS confirmed the 3 mph gain. In fact I got a bit more when I went rougher. It lets the boat "break free"

I dont have a miniz boat yet. But all of my boats (only 4 at the moment) have sharp sanded epoxy running surfaces. Or sanded abs sheet added to the sponsons to make that sharp edge on the trailing & side surfaces. The sharp edge on the transom is prolly even more critical. I think some guys use micro balloons and CA glue to build up a edge for this on plastic and abs hulls. The F1 looks very rounded at the transom edge and the pictures of it running that I saw looked like it could not plane out with the bow up and the transom deep in the water. And if Im not mistaken. It looks like the rudder is the Outboard?? Does the drive line have a universal at the outboard so the prop turns with the outboard? If so , it needs to go. ;) You would be suprised what more you can squeeze out of a stock slow boat with alittle work. And with small micro boats everything is home made & cheap. runrunnerracing.com is a good place to read and ask about electric boats. And microhydros.com is also cool. My boats are pictured there. http://www.microhydros.com/mike_kolder/mike.htm

My 10" V is so fast, it runs like a skipping stone. In the air half the time but stuffs under water sometimes. So if a 10" hull can float a speed 400 & 8 cells. I bet the Miniz F1 could float a mamba and lipo's.

[LBRC]

The waxing or sanding sound interesting, probably try waxing first tough sanding sounds sort of irreversible :eek: .

Still need to get a prop set, unfortunately constant rain and 40 degree temperatures have literally dampened my interest in boats so I keep forgetting to order the prop set. Wonder if you could find a good brass prop that would fit?

Did finally get an Aquaspeed in it’s a definite improvement but a BSRT Spinner 34 is much faster while using less battery power (balanced, trued comm with a nicer endbell) and one with a custom modified 31 gage armature is faster still, of course they cost quit a bit more though. Definitely think a brushless motor might be interesting although not sure about the mounting, sort of seems like you’d have to redo the whole shaft and prop set-up or use some sort of offset gear arrangement.

[ruf]

Skip the wax, try the sanding. It's proven fluid dynamics (boundary layer and laminar flow). Same principles that make a dimpled golf ball fly farther. From superbikes to helicopter blades (rotary wing), turbulators are used to manage the boundary layer to improve laminar flow. I've actually seen them for use in 1/10 touring car bodies! The principle is that fluid-on-fluid is slicker than fluid-on-surface. Fluid can be air or water. By disrupting the flow in a controlled fashion, you can create a "skin" of turbulent fluid that will decrease your drag. You just have to make sure that the "skin" doesn't get too thick or you will end up worse than you started. A slightly rough surface on the hull should be suitable.

That's the best way I can describe it. I suck at this stuff, but I've had some smart ppl explain the basics to me.

[dean]

I'm just wondering if we put forum thread 'Header" for the F1 boat maybe it will renew interest. They have a lot of potential that is being missed out on. :cool:

[LBRC]

Might not be a bad idea there are a few more models now, and I would definitely like to see some homemade race courses.

Should be possible to build a sort of 4 inch deep meandering stream out of pond liner, I was thinking of something approx. 3 to 4 feet wide with a couple of switchbacks, and a 5 to 6 foot wide 30 foot high speed straight down the back with slalom flags. Would even be Core timing system compatible.
Somthing like this (http://lbspd.com/v-web/gallery/albums/album67/Mini_Z_boat_pond.jpg)
Heck if I sort of landscaped it in the wife might not even kill me. Problem is that although I have plenty of space it’s not exactly level.

Did finally get the prop set but the winter sort of dampened my enthusiasm for boating, although now that the weather is improving it might be time to try them out.

[dean]

Nice idea.
I already bought a 12 x 20 pool cover for 4 inches of water.. If it is a good size I will make a video. I already got the boat to perform well for a 3 or 4 min fast race.
My other idea is i have a great pond nearby with no overgrowth all year. It is shallow.
i am thinking of useing 8ft 1/2 inch pvc tubeing some cut to length with waterproofed closed ends then styrofoam blocks painted red as flotation device for pipe jammed on ends and then weights with string to anchor it from floating away.
Im sure 2 people would be best to set it up . One to hand out supply as needed.

Again. MiniZracer..please put up a main topic for boats pease!!! Such as Newproducts, Videos,Overlands...and BOATS! pleeeeeeze
These are mini-z's and should not be overlooked...again THX! :rolleyes:

[LibertySyclone]

Just as a note for the sanding and the non-believers, have you looked at a golf ball lately? all those holes create a vortex and make the ball fly faster through the air.

here is a link http://entertainment.howstuffworks.com/question37.htm

The same theory applies to cars and boats

[fastskater21]

Finally got re-registered to post there.
I have both boats with the Aquaspeeds and Prop-sets.
I am also custom building an Offshore Catamran hull for the
"3rd" formula boat I purchased for the "guts" to match
my 21 foot Skater Cat. I will try to post the pics of the hull
as it gets completed.
I love the boats and I have yet to still try out my 6-cell 150mah
batteries. I am running the 3-blade prop with great results.........
for the first minute of running! Once the Aquaspeeds are broken in
the seem to be great runners. I noticed that they are VERY trim
sensitive. I will also be trying out the "sanding sponson" trick and
will report my findings... I also love the idea of a "track" to run these
things on. My friend has a tiny pond that we are going to race on this
spring at his house.....More to come.......

[fastskater21]

Lets see if these pics work!
Custom Catamaran Skater Hull

[fastskater21]

She may be ready in a couple of weeks to try out.
I still need to finish the deck and drive unit.
If it runs well, I will attempt to make a mold for the upper
and lower half and make a light weight fiberglass version.
I felt it was necessary to make "Rough Water" boat as
the stock Formula hull sit very low in the water, but they seem
to manage fine once under way. I hope mine handles the
heavy chop better. I made a funny,.... heavy chop.... with a micro boat....
Ha, Ha,......

[dean]

Wow! Impressive craftsmanship.

I'm down at Franks Trains and hobby in FLA to race the oval track, but really wish I brought my F1 mini boat. The pool in the hotel im staying is godlike.

Ha, Ha,......
I like the look of the cat, can’t wait to see it finished.

I finally settled on the 600mAh LiPo pack because of my motors current requirements am currently using a custom motor made by BSRT w/30 Spud armature it’s a real screamer but also a current hog even if balanced an trued, fortunately the 2x2 4562 FETs are holding up, BTW thank your Kyosho for putting the extra pads on the circuit board so the FETs don’t have to be stacked. Anyway the battery pack unfortunately weighs 8 grams more than the stock 120 NiMH pack which isn’t much but as you said the F1 hull already sits very low in the water and even 8 grams more is noticeable, it’s not so bad once I get moving but if I hit any chop it is starting to get exciting and if I throttle back to fast… lets just say that the F1 isn’t exactly water tight and the pond water in the great NW is not exactly room temp :eek: .

Have started on my landscaping project, lol the wife as predicted is somewhat skeptical about the hole thing and I have to admit that when stacked out it is looking like a good deal of work, trying to level the required area, unless I can find someone with a Bobcat they are willing to lend me ;) .

[fastskater21]

Thanks for comments guys! Since we are talking boat here,
what are you guys finding the best set-up is? For most water (calm)
I find that the 3-blade prop, Stock battery, Aquaspeed, and most inportantly
the prop shaft is nearly in line with the drive shaft exiting the boat bottom.
Since I am into full size boat the run with a Surface Piecing Propellor.
I have decided to remove the lower unit from the Kyosho outboard
and install a propeller directly on the output shaft coming out of the bottom
of the boat in an attempt to get some more RPM out of the motor.
I made a small rudder that now slips in original bottom side of the outboard
and use the clamp screw to hold it in and that way I still will have steering.
I have two shafts made up with the props at different lengths out of the
drive shaft tube. I may try it out tonight if the wind is low.
Has anyone tried messing with the trim tabs? I may take them off
completely to see what happens as well. Glad to see others enjoying
and modifying these cool little boats!!!

[LBRC]

Can’t be much help on the boating aspects since this is the only boat I’ve ever tried, but I can help a little for anyone who wants more than the Aquaspeed in the way of a motor.

These precision balanced custom slot car motors made by BSRT in Seattle will fit in the Formula 1 boat, although you will need to cut a hole in the bottom of the motor box for the slightly larger rotor.

Note; due to the high number of turns slot car motors like the Mabuchi square can are not rated by the number of winds instead they are rated by the gage of wire used to wrap the rotor so the smaller the number the larger the wire diameter resulting in fewer turns and a faster motor.

When going to the following link you will notice that the motors only go up to 34 gage, which although hot is not exactly extreme for the F1, it is however insane for a slot car at 18 volts so although they make and advertise them they actually try to discourage slot fans from buying them. So you need to explain that your not using the motor in a slot car but want to put it in a boat, once you get over that hurtle if your nice you can even coax them to wind a 33, 32, or even a 31 gage motor for you. Of coarse you will then need upgraded mosfets, and batteries with a higher capacity capable of delivering a little more current too i.e. LiPo’s. Also since the motors are made to run at higher voltages the timing is a little advanced but that actually seems to be a plus for a boat since you don’t need much low end torque.

I am gald to see more people posting and sharing
ideas on the Formula Boats!!! I really liked the Water RCP Track!
Here are a couple more picks of the custom hull.
By the way, Last night I tried out the direct drive prop right out the
tube on the bottom of the hull and I saw an increase in speed. and
slight cavitation in right hand turns.......But, this mod seems
to be alot more efficient than running thought the flex joint.
I am going to keep testing this as I really want to utilize the stock
battery/Aquaspeed/props that are readily aval. to purchase.

[briankstan]

It could happen ! :rolleyes:

That is WAY COOL....ROF LMAO

We've tried the RCP boat track at IhobbyExpo last year and at Hobbyvissions in 2004. It worked very well.

This pool was at my hotel when I went to Frank's Hobbies in Florida.

I was wishing I squeezed in the F1 boat into my luggage especially because the pool was vacant all the time.

[sciencemike]

I desperately need some help...

Can someone measure the prop on one of these boats. I need the diameter of the whole unit and the shaft diameter.

Im looking for somthing in the 15 mm diameter size with a 2 mm shaft. Anyone seen anything like this?

[LBRC]

The prop diameter is approx. 12mm with the hole being just a hair under 2mm so that they fit snugly onto a 2mm shaft.

Cheers

[sciencemike]

I have been searching for 3 days!... I love you!

Where do i get me a set! And whats the highest pitch they go?

[LBRC]

I have been searching for 3 days!... I love you!

Comes with two each per set:

D 15 x P O.8/2
D 15 x P 1.0/2
D 15 x P 1.1/3
D 15 x P O.8/4

If the shop here doesn’t have any I believe Apex has them in stock at least they did a couple of weeks ago when I was collecting supplies to take north with me, if you have trouble finding any PM or email me and I will get a price for you.

Not quite.. but that would be cool!

Unfortunately Its a very long story and a picture would be better than a thousand words. Later this week i imagine....

Mike

[Shrubba]

The drive shaft that comes out of the stuff box is smaller than 2mm. How would I connect the prop to the smaller shaft? Or is there somewhere I can buy props with a smaller hole?
I'm really looking forward to modding this thing!

Sanding the hull is the first on my list. Then the upgrade motor. Next I need a better battery.

Oh, the lipo battery packs people have been talking about, can that be charged from the trailer?

What rate do you charge your 130mah packs on your peak chargers?

[LBRC]

Oh, the lipo battery packs people have been talking about, can that be charged from the trailer?

No, absolutely not.

[Shrubba]

No, absolutely not.

Didn't think so, figured I would ask.

Any idea on how to mount a prop on a shaft that is too small for it?

[LBRC]

Some sort of insert.

Hello, I acuallly made the prototype shaft from music wire that is alittle
bit bigger than the stock shaft. It is closer to the I.D of the stuffing tube.
I super glued the props on with a small amount of fuzz wrapped aound
the sanded shaft for the prop area. I as able to build up material on the shaft with some CA and a loose fiber rag that I ran the shaft over with the
wet glue until I was able to CA and press the prop on. Surprisingly I was
able to get them perfectly centered and ABSOLUTELY no vibration.
If you get it right, there is very little to no extra noise at all other than
from the motor. You definately need the Aquaspeed motor to see full
potential, but remember you will still have better run time and much less
heat build up as well.

If you ever end moulding those custom hulls, let me know.. I'd be intersted in one.

You know..... I am still thinking about pulling some super light weight
fiberglass hull/decks from this model....I need to read up on how
to make a mold from my model and them make. The shape if the
hull really worked good on the lake except for being heavy.
If I can really get it light. It would smoke the Formula hull just in
efficiency. And it should give the new Kyosho Catamaran a run for it's money.
Please let me know the best way to pull molds from my prototype if anyone
knows best. Once the molds are done, making the Carbonfiber/ fiberglass
hulls and decks is easy......ANY IDEAS?

I tried searching for a useful article, but wasn't able to find anything yet.

If I do come up with something, I'll let you know.

I remember I was driving an electric rc boat on the ocean, the wave washed my boat away. Hopefully, this one has a better engine I am looking for. :)
