View Full Version : EMU Racing MR015 to MR02 Front Track Conversion

I have always preferred the transition response and rotation through the corner on the MR015 chassis more than the MR02. The MR015 may have a higher center of gravity, but the mass is more centralized.

What cripples the MR015 chassis even more, is that if you want to use a wider body, you have to use wide offset wheels. Which increases scrub; which reduces the steering response.

I have wondered how the MR015 would feel with the MR02 track width. So I tried a few PN MR02 tower bars on a modified MR015. I liked what I felt, a lot. The car was very stable, but rotated into and out of the corner better than a similarly setup MR02 with the same body.

I feel that the MR015 with the MR02 track width, can be just as competitive as an MR02. On low grip tracks especially.

I have had nothing but good comments from the test drivers, and locals that have the part.

The tower bars have 0d camber, and .5d caster.

I even have one installed on my Road Course Nascar. I did narrow the front wheels and tires a little ;)

I cant seem to edit the post...
These are available now at Reflex Racing:
http://www.reflexracing.net/proddetail.asp?prod=EMU015R

They are also available at all three of the local NYC Mini-Z tracks/shops.
Action RC Speedway
NYRC Super Raceway
Maj's Hobby Shop (MHS)

I will not be selling these individually, if you would like one you are better off getting one from Reflex. If you are interested in 10 or more, you can contact me directly for a discount.

i totally agree with emu and his points on the mr015... ''The MR015 may have a higher center of gravity, but the mass is more centralized. What cripples the MR015 chassis even more, is that if you want to use a wider body, you have to use wide offset wheels. Which increases scrub; which reduces the steering response."

i definitely understand the scrubbing... back in the mr01 days, everybody was using bulletproof clk's (with +2.5mm front offsets)... and after comparing notes, it all seemed that everybody (using +2.5mm front offsets) experienced heavy understeering...

you just couldn't attack a corner or hairpins aggressively as compared to a body that didn't have front offsets...

experimented with wide rims all around, and this proved to be a bit more effective (until a third party manufacturer came up with knuckles with camber in them)... but even still... after a while the understeering would tend to creep in after the tires wore down...

i've thought of this before and always thought that pn had made this part, this since they did come out with a mr02 to mr015 track width conversion...

i thought it would be natural to have a mr015 to mr02 track width conversion as well... guess i was wrong...

would love to have tried this out... hope that i could get my hands on this part... congrats emu on coming up with this thing...

i see nothing but rave reviews coming... (i figure it will be quite similar to what reflex racing's wtf system is doing for modified mr02's, by replacing rims with offsets, to rims without offsets)

now if we can have tower bars in different lengths, (mainly to... uhhmm offset the (rim) offset... yeah kinda sounds weird - will probably end up costing a lot because there are lots of offsets out there :D) this will enable you to use a front rim that will have 0 offset... and offer you better steering response... :D

The only thing left needed to complete the front track width conversion is the MR-02 Tie Rod correct?

I didnt have any white 1N wheels... so I used the LP500S gold front wheels. :rolleyes:

You know, I allways use white wheels, unless I cant find ones in the offset that I need.

Got mine last week and all I have to say is WOW!!! I cannot get over the amount of rotation that is produced... the car feels very stable and predictable... all the guys at MHS are converting their 015's.... im running it at 98mm with the nissan body.. plus 2 rear plus 1 front.... super competitve for a simple setup.... Thanks Eugene!!!!!!!!!!! Keep up the good work...

GIHOSU
2009.05.24, 02:23 AM
Junior... I can see your WOW, and raise you to a "Holy $#*^!!!"

I happen to already be a MR-015 lover, I'm faster with them than my 02's now. While I was fighting with my 02 tonight, my 015 was just a pleasure to drive. I was on a big new high grip track tonight and drove my EMU-mobile for the first time. The ability of this setup to rotate and transition is smoother than ever. I had such a big smile on my face it hurt.

This really upped the ante. Thanks alot Eugene!

Im glad that you both like it. I produced the tower bars because I wanted to use it bad enough to get them custom made. I have wanted to do it ever since the 015 first came out. At first I thought that either PN or Atomic were going to do it... But the part never came. So I took a big gamble, and put my money behind the idea.

The main design is based off of the PN .5d caster tower bars. Besides the screw holes on the upper tower, they are identical. I thought about only releasing the upper tower, but that would make no sense without having the lower tower available seperately.

I even thought about making it compatable with both MR02 and MR015, but that just over complicated things, and would make it too expensive for me to have produced.

GIHOSU, your car looked very smooth today... And I barely saw you do any setup work on the MR015. It ran very competetive in the ATM USA spec motor class. With a little more wheeltime behind the setup, I think it will be even better.

GIHOSU
2009.05.24, 02:58 AM
EMU, you're right. I build the car up last night and used my favorite MR-015 setup but set it up for 98mm... Hard rear and a soft front, ATM AW-40's up front and Kyosho 20 radials out back with my trusty old McLaren. The only change I had to make all night was to go from a hard PN t-plate to a Kyosho medium carbon t-plate. The car felt so dialed.

I am a solid B-main racer, lately I've been able to get more practice time on the track and it has really paid off. I feel that my performance in Spec class was pretty good too. There was so much grip tonight that it took some laps until my driving could deal with the high front grip. New RCP is so nice, it's been a while since I have been on such a nice new surface. I want to see how the ATM Spec motor runs, when I was marshalling they sounded so good winding up on the straight.

This car is giving me a serious "I need some RCP at home" vibes.

Now I want a EMU-LeMans.

EMU
2009.05.24, 03:34 AM
It is bold, but I do think that a 70t or Atomic USA powered Mazda 787 body with an EMU MR015 would have a strong edge over an MR02 LM car with the same motor. Faster motors, it would be a toss up.

The LM cars are so wide, that the mass centralization of the MR015 would definitely benefit the handling without sacrificing the stability. Basically, you could use slightly more rear bias in grip.

I plan to build my Nascar road course car into a Mazda 787 after the season is finished. Should be very fun to drive.

How will the EMU car work out with a pan car setup? Has anyone tried it yet?

EMU
2009.06.02, 01:56 AM
You have to use the Atomic 94mm VDS 2.5 body designed for the MA010. Or, you have to modify the pan body of your choice to clear the battery compartment.

When we had an MR02 70t pan car class, I had left my pan car at home... but had just received my 94mm VDS 2.5 body from the paint shop... I set up the car in about 20 minutes, and finished 2nd in the main. I was only permitted to run it for that race, so no further development went into the car. It is now the Nascar above...

The car had good rotation, and felt good, not quite as good as my MR02 which had been through about 10 weeks of development, but close. Considering that this was a throw together build with less than 30 minutes of work, I would say it was very good. The body sat very low, and rubbed the track on hard corners, so I couldnt push it too hard.

mugler
2009.06.02, 02:57 AM
Yeah I just tried to clip my 015 chassis in a PN pan body and realized the clearance issues. Good to know the VDS option is there though.

I thought i'd chime in now that I've had some good runtime with my 015 to 02 conversions from EMU:

This past weekend I set up a very turny RCP track at my house.
http://i13.photobucket.com/albums/a258/CowboySiR/summerraceseries015.jpg

Right out of the box the 015 was the most agile yet the most planted car of the fleet. EMU's conversion allows me to run 0 narrow fronts on my F430 body instaed of the wider offsets (and possible wheel/suspension jacking issues from said offsets).My setup is very basic yet the combination of aggressive body, soft rear end and EMU's conversion makes for a very pliable yet traction friendly car.

Once I got in the groove of the layout it wound up being second fastest on the day with stock 3010fet and stock motor.:D

-J-
2009.06.02, 07:15 AM
Faster than a MR-02 of similar specs? I'm not doubting you, just trying to finalize my decision for which 2wd mini-z to get, and this is making it interesting. :D

cowboysir
2009.06.02, 07:30 PM
I don't know if I'd call it faster in itself. but the setup combination of the wider front end (thanks to EMU's tower bar) reduced suspension jacking, an aggressive body style (Ferrari f430) and a pliable car setup (medium FRP RM plate and medium kyosho front springs) made the car perform well on the track layout shown above. Responsive turn in with just enough tail release to exit the corners on a good amount of throttle.

It's no doubt that EMU's tower bar improved the car...in combination with other elements it made a very capable competitor to my simliar MR02's on this track.

2009.06.03, 01:17 AM
I had planned on saving for an expansion pack and a couple inside radius turns. In the grand scheme of things my home track for the four or five guys who show up is good enough for now.

You are right though tjay...it makesd driving in anger a bit tight in places.

Back to the point of this thread is that my 015 is better for knowing EMU.:D

mugler
2009.06.03, 03:27 AM
well my tower set is on it's way. I understand you were running the EMU car in RM on that track any input on MM 94 & 98? I guess EMU already mentioned about 94mm with the Atomic 2.5 pancar but was that in MM?

EMU
2009.06.03, 03:36 AM
Mugler, I have all of my 2wd cars setup MM. I like the way that it feels in both 94mm and 98mm, even 102mm... although I cant wait to take off the Nascar body/wheels/tires and get an LM body on it...

TJ, havent been able to hit the Post Office yet, tough to get there before work. And after work, impossible. I am going to make sure to get there tomorrow ;) I have a few packages that I need to send besides yours.

Im really digging my EMU bars. Ive been trying a lot of things out with body slection lately, and have been really liking it in 98mm config, with the Mclaren F1 GTR.

I really liked in in 96mm with the 350Z too. Im going to do some testing with narrower offests in 98mm today, and next week. Ive got the NSX stretched ou and ready to go, as well as a 350Z.

Track is too long and too tight. Open it up a bit... 3tiles wide on some...

I dont know why you west coast guys are all hung up on three tiles wide. The cars are only 3" wide, lol.

http://img.photobucket.com/albums/v618/freekfornature/RCs/tracks/2009-05-07046.jpg

This is our track. Its tight and turny, but there is plenty of high speed action and overtaking going on at our club races. There are a few wide radius turns, but other than that, no blank tiles.

wondering if there were any mr015 specific tower bars made? just in case you wanted to go back to the mr015 track width...

If you mean making your MR02 into an MR15, yes they exist.
I have a pair that I bought 2 years ago from EGR racing (i think).
But they are hard to find now.

herman
2014.08.19, 10:00 AM
Yes I know there are tower bars for the mr02 to convert to mr015 track width.

Actually I'm looking for the regular mr015 tower bar (if it was actually made)... It's for the mr015, to turn it back to mr015 track width. So you have the option of converting your mr015 to mr02 track width (c/o emu's mr015 - mr02 tower bar conversion) and going back to mr015 track width... :D
