Hi xsracer, the part of the rules I was concerned about states "kit 5 coil chrome springs" yet the tt02r (from tower hobbies) came with black 5 coil springs. Not sure of the spring rate tho...
I was there last year too running a red m3 tt01r type e. Lotsa fun! Not sure about the motor either. I hope it'll stay together. Definitely not enough gearing to support a 21.5 on that track.
Oh yeah! Getting it ready now, thanks!
