Thanks Eugene. Keep it coming guys. I would share my set-ups but I feel as they are negligible to most people. LoL.:rolleyes:

And Eugene wins the award for broadest use of 3rd-party parts suppliers... :D

I'll never claim he is a corporate shill!

If Eugene and others could also post what bodies they're running I'd be interested in knowing. Body has a big impact on setup.

As far as bodies...
Mod GT I have been using the F430GT at 94mm
Lemans I use the Sauber C9
Hatch I have used R32, Subaru STI 94mm hatch version, and Megane. The Megane handles power best, and is about .1s faster than the STI. R32 is just a little too small and light. Since the chassis that I use the hatch on has a narrow front, I can switch between each body pretty easily. I may want to try the R32 with narrow rear wheels, I think the AW10 would provide enough grip with the power that I have, and due to the low weight provide better acceleration. The main drawback, is that any contact would put me on the losing end of the battles...

Racing for Reflex, I try to use as many of their parts as I can. However, I have many cars for different purposes, and have many parts from before I started racing for Reflex... So I put them to use when needed. The LM car was setup when I was racing for ATM, and has gone through very few changes since its inception. I plan to switch the tower bar out for the Reflex for the next race as I think I need a little more camber and caster.

Take in mind, that the track surface is carpet, so the tire choice is different than what you would want to use on RCP. Although my setups are the same setups that I race RCP on with different tires...

Hello Eugene, Im having a hard time finding speed in my ATM 40T 17mm motor. My gearing is 53/12 64 pitch as per Sai's suggestion but it seems like my 48T 17mm (53/13) is faster all around. Can you give me any advice as to which route I should go. I'm using this in mod class by the way. Thanks buddy.

Try to gear down a little... I know it sounds funny, but I have good speed at 53/9 although I am thinking about going to a 10 to see if it gains any more speed (which I dont think it will gain much). I fear that if I gear up, the lack of torque will slow the motor down, and it will start to get hot. Also the motor will not have the power that I want exiting the corners.

Is your motor hot after a few minutes run? Do you have the fets upgraded? What batteries are you using? How old is the motor, has it been broken in, or just run?

I havent broken in any of the 17mm motors that I have used. I usually dont break in mod motors, besides running them for a few minutes dry... I do not recommend water dipping mod motors, only stock bushing motors. I dont want the water getting in the bearings at all...

One thing that I have been thinking about trying, is using an old stock motor to water dip a new mod motors brushes, then moving them over to the mod motor after they have been broken in on the stock motor. While it wont be a perfect mate to the mod motor, it wouldnt wear the comm on the mod motor, and the bearings wouldnt be subjected to the water...

I'm pretty fast for 2WD Mod but not so for 70T Skinny.

Feel free to ask me a question.

Rather than listing every part in detail. In general I run 10d in the back and 30 / or even 20 AW Groove in the front. My front springs are generally harder for carpet racing compared to RCP. I prefer torque over speed so I use 48T instead of 35T. These are the only motors I use.

emu have you ran the 48t 17mm? if so what gearing do you feel is best on the motor? i ran it with 12/53 and it was a little quicker than 11/53 but i found it to not be as smooth of a powerband. the 11/53 felt better but was a good 2/10ths slowwer.

I had the 48t 17mm motor in my Hatch car (which was actually the f355 that I had raced at the first Carolina Cup with very few changes). The car was pretty quick, but not quite fast enough to face most of the motors that I was going against, which is why I switched to the 40t. I feel that it has a smooth power band... and I actually like how it drives, I just want a little more power for the grip that I had. On a low grip track I think it would be a great motor choice. Or as a spec motor. For gearing on the 48t I used 11/53.

Hello Sai, thanks for dropping in. I'm going to be changing to 48T round can in my mod after seeing my Megane/ Hatch do a 9.5 easily while I barely do the same with my mod car. The 40T just doesn't have that punch I need in the infield but it has a very linear power-band that I am impressed. Hopefully I can find use for the motor.
