All I've run are shorty packs w/ the SP Reventon-S 17.5 fixed timing combo - sensored. Battery is all the way back, with a low profile servo, ESC behind servo, reciever, then battery all in-line.

Only run on carpet though, but dailed. It simply goes where you point it.

Big box from Speedpower due tomorrow.

BTW, I agree with the 17.5 motor for the class. I decided to to with Reventon S and 17.5R with timing motor: max timing restricted to 20*, min at 11*. Tires should be teched for minimum diameter until rubber tires come out. Now if these tires wear like iron due to their unique construction, I won't mind staying on them at all. My CRC WGT was never hard on tires. Once the camber was right the front tires wore evenly. The rears lasted a whole season and the fronts would last 3 to 4 weeks including practice. The LM-1 so far looks to be better on tire wear than that.

As far as gearing, the 17.5 would probably be better at 72/20 to 72/24 on carpet, depending on rollout of course. That's an FDR range of 3.5 to 3.0. I prefer not to let the smoke out of my electronics.

Weight - What are we going to run at?

Everybody that has run the car so far...have you had a chance to weigh your car before going out? I looked up the ROAR rules and for Can-Am/GTP/WSC (the best derivative I could find) and the minimum weight translates to about 1200 grams so Id go with around that as a starting point, but Im curious what the guys that have run laps with it have had for a weight

Stock build, no carbon anything, no alu or ti screws.
Reventon-S ESC, SP 17.5 fixed timing motor.
Airtronics low profile servo.
Airtronics reciever.
Transponder
Peak Racing 4000maH shorty pack

Ready to drop on the track weight:

1263 grams

Should you spec a weight...1200grams seems pretty spot on.

Would probably spec a minimum for both LMP and LM1 just to put everyone on a relatively even plane to start.

Well we would probably only spec minimum weight because everybody would be running different gear.

A shorty pack is almost worth a 100g right there...

1240g? Not bad.
