This would be a nice upgrade much better mesh when I ran slots this was on of the first upgrades when we built a car to race. :D

I know this is gonna sound dumb:eek:, but what are these exactly? Is there a beenfit to "64 pitch" gears opposed to the diff gears that PN already has available?
Thanks :)

Saw them at Kenon this weekend. They look great. (at least the pinions which is what I got to see)

The benefit of having 64 pitch is that #1 you have finer gearing options (to better tune your gear ratio to the specific track/ motor you are using) and #2. They are much more efficient.

hmm... so will that mean that they'll have 64 pitch both in pinion and spur gears?

what's kyosho's original pitch in the stock pinion / spur gears?

wcrotty
2008.01.13, 10:37 PM
Yes both the spur and pinion have to match.

I'm not sure what the pitch is of the original kyosho gears but i believe they are the same as the hpi micro rs4.

Lol Christian, you sure get around. You were in NorCal just 24 hours ago. :p

An original Kyosho 44t spur is a bit smaller than a 48 pitch 44t spur, so I'm inclined to believe they are 0.5 module (roughly 52 pitch). But they're close enough to 48 pitch (which is AFAIK the MRS4 gear pitch) to be cross-compatible.

My BS above doesn't really matter, the important thing is that hopefully the new gears really will bring an improvement in gear mesh. The geartrains of these cars are so much louder than they should be. :rolleyes:

Kyosho Pinion is M0.5 (around 50.8 pitch), the problem is the Kyosho and all after market Spur Gear 44T on M0.5 suppose is 23mm diameters, but they change the diameters to 21.9mm, the pinion is not prefect match, it will be noise.

If all the Spur and Pinion is same pitch, it will be smooth and quiet.

anyone know if the spur gears will fit on kyosho brand ball diff shafts?? or just on pn brand ball diff shafts only. it would be nice to upgrade existing kyosho shafts. here's hoping

not positive but i put a kyosho diff gear on to my pn diff so i think it should work fine

Hmm, I hope they will release some smaller pinions, now we drive with 6-8 on our tracks, that means a final gear ratio of 7.3 - 5.5.
The 7.3 can't even be reached with the 64p :(

herman
2008.01.17, 01:17 AM
how's the acceleration? and is it quieter than stock?
i'm thinking those pinions are for huge high speed tracks... :D
wish they'd come out with smaller pinions too... but that might be a problem with 64p...
can you post pics of the pinions? :D

we have been testing the prototype 64p gearing at kenon rcthis past week
as far as i can tell thoes whio have it LOVE IT!
smoother accel and less drag on decel so quiet and smooth
with the new gearing ive been able to go from 4.3(10/43) to a ratio of 4.0(13/52) because my car is so much smoother and responsive bringing the lap record down to 7.9 from 8.1....
another thing is that the new gears show little to no wear.... unlike the aluminum or delrin pinions that i have been using
it also seems to make the car feel like it can be more consistent
i am told that these will be avail

Philip sent me the 64 pitch gears this week to test and my first impression is WOW.

The gears are smooth. There was NO loss due to the gears not meshing right. After letting up on the throttle my car would just role and role with little loss due to the gears.

My car was also very silent too. It was funny running a race and i had the stealth car with very little sound.

I felt the car had more acceleration. I'm not sure if that was due to less loss in the corner and that increased my corner speed. Or if the car accelerated faster out of the corner. Either way with the 64 pitch the car had more acceleration.

The new 64 pitch gears are another step for mini-z cars becoming great racing machines. Two thumbs up for this product and a big thanks to philip for making a quality product.

I highly recommend 64 pitches. Makes the car more efficient, more quiet, and smoother throttle response.

This is a new PN Racing product too, but for standard gears:

Mini-Z 2WD Pro Match Delrin Pinion 7T-10T

The prefect match to Kyosho or PN Spur gear pitch. The gears are smooth. There was NO loss due to the gears not meshing right. After letting up on the throttle my car would just role and role with little loss due to the gears.

It will be make your car like stealth car with very little sound.

HaCo, Philip also sent me a set of them to try out and they worked great.

I do like the 64 pitch better though.

Herman, I have a bunch of pics of the 64 pitch gears but the gallery is down and i have no place to put them.

Hi Bill,

Should I e-mail you my home address so that you can send me your spare 64 pitch gears? Thanks man! :rolleyes:

Ok,

I was able to post them on a site. Sorry the lighting wasn't perfect.

Here are the pinion gears. Perfect match on the top
and 64 pitch on the bottom.

Here is the 64 pitch spur on my kyosho diff. (I had to modify the diff to get the kyosho diff to work) I will come up with a step by step process to do this . I sent philip the info on this so i think he might post it on pn.

http://www.mnm-hobbies.com/pngears/IMGA0418s.jpg

Here is the top view of the diff with a perfect match spur behind it.

Use PN Spur gear at Kyosho MZW206 MR02 Ball Diff (modify request)

Pic 1 & 2: The inner hub of the diff extends slightly outward from the diff ring. With the new gears that bump gets in the way and will not let the gear sit flush with the diff ring.

Pic 3 : Use some 400 grit sand paper.
http://www.pnracing.us/kbdm3.jpg 

Pic 4: Lay the paper on a flat surface then in a circular motion sand down the hub. Keep checking the hub and stop when it sits flush with the diff ring.

Pic 5 6 & 7: Here is the sanded down diff now sanded down enough for the PN gears.

Pic 8: Here is the Diff with the gear installed before the outer hub goes on.
http://www.pnracing.us/kbdm8.jpg  

Pic 9: This is the Kyosho Diff with the new PN 64 pitch spur gear installed.

This was very easy to do and only took about 15 minutes to complete.

These gears, either the 64 pitch or super match, should be considered a first upgrade for mini-z. They are just as important as ball bearings. The original Kyosho gears are mismatched. They have .5M pitch on pinion, but a truncated .5M pitch gear for the spur. After couple of runs, you can already see excessive wear on the pinion. One time, I ran the pinion down to see what would happen. The noise got louder and louder. Soon it sounded like a group of people talking at the same time like in a party. It was late at night, with no one around. It sounded a little creepy. Even my wife said she heard people voice, but realize it was the car. Very strange.
I have been using steel gears from RS4, and they last a long time, but the super match or 64 pitch should be very durable and have better performance. Can't wait to try them.

will the spur gears fit the Kyosho F1 diffs with the same modification? or are these limited to on the Racer Diffs?

hpgod
2008.02.12, 01:45 PM
I coverted my f1 over to a 02 gearset this last raceday when i was searching for more rear traction. The Pn mount made the gear mesh much easier to set right.

It can be done using the PN motor mount but I do not think the stock mount will work unless you run a large track where a very large pinion gear is required.

Do the Kyosho balls fit the 64 pitch spur?

2008.02.18, 04:30 PM
Yes they do, most MR02 ball diffs use standard 3/32" dia. balls. ;)

These gears run sooo quiet and are super smooth. I like the fact that you can manipulate gear ratios in smaller increments, but also can go VERRRY extreme on either direction as well. BIG THUMBS UP!!!

I agree. Got to run them for the first time this weekend. Smooth, quiet, stealth like.;)

CristianTabush

Beware of the molding on these though. My only beef is that you have to scrape the injection molding spots on both sides with an x-acto knife. If this is not done, this makes the diff drag just slightly, not leading to as smooth diff action as with other spurs... Once this mod is complete, they are excellent, but in my opinion, are not direct bolt-ons since this material recessing has to be done...

i guess the next obvious question is, will this development translate to awd pinions, gears and spurs?

CristianTabush
2008.03.09, 04:55 PM
Byron, it is not every spur that needs this, I noticed it is only about 1 out of every 2. No pictures, but if Joe ever gets his stuff together maybe he will post his tutorial on how to build a diff his way :P on the ReflexRacing site.

Arch, I doubt the spurs will be made like that for the AWD. Just would not be too practical since you would probably have to have 20 different mounting plates for the motor :o
