IRH Setup
Hi,
i am just finishing my rear motor build to race at island hobbies this fall and winter. i figured id start rear motor and go from there. i got the new alloy hangars for the rear and wanted to know if anyone raced rear motor what was a good setup please? should i do the narrow inserts or wide setup? and with stock rear a-arms or um521-1 arms and with which respective insert for the new version hangars? also a general setup would be appreciated if possible. was concerned about battery placement as well. if any one could help with particular track i would greatly appreciate the help. thanks in advance.

Hey Everyone,
I thought I would provide a quick MM update.
First of all here is the current layout that I've been running for about two weeks.......
Car has been good but I think it could be better.....
I started out with the stock pistons and 30/25 oil just as Hara used at WCRC......car was bouncy.....went to a white AE spring in rear....car had more rear bite on power......but not as much as I had hoped for....I then went to a higher rear roll center and things got better........
Next week I went to 4 hole #55 pistons and UM521-1 rear arms.....and .5 degree hubs...... oil was 35/32.5 and now 35/30. Car has been pretty damn good.....although I'm now disassembling it to go Saddles.....I'm convinced the extra weight is the answer to getting this car dialed on lower bite surfaces.
A few guys at my local track also run very soft suspension packages on their rear motor cars......something in the neighborhood of 4 hole #55 pistons with 25/25 or 27.5/25 and they have had good results......may end up giving that a whirl......
Oh yeah....after talking to Carson Wernimont I decided to add more droop.......MAN WHAT A DIFFERENCE! Made the car fun to drive as opposed to punishing when you land flat bottom.......which CAN be faster in certain portions of certain tracks...........not all jumps are faster when downsided
Oh well....thats it...I should have a video out soon on this car.....so far I'm pretty impressed.

Tech Regular
My current setup for mid motor, waiting on a rudebits lipo tray and will move the receiver to the back of the car so I can shift the weight around a bit more.

What's interesting is he isn't using the KIY radio

I think the interesting part of Tebo's latest mm setting was actually the shorty Lipo. Previously on all his set up he is using saddle, and the fact that the shorty is placed like what you did on a RM is also something we can all think about.
So for MM, shorty or saddle? Hara's method or Tebo's? This is gonna be a very interesting worlds :-D

Maybe I am reading to much into this or just not able to comprehend what is being said. With that said, perhaps IFMAR doesn't have the same or similar battery rules as ROAR as to how they are mounted into the car? Thus his decision on the choice of battery to use has changed.

Does anyone run drag brake....I've only ever ran Stock with no drag brake. I am now starting to run Mod and was wondering what most prefer drag or no drag
