Another one for Speedpassion! I raced this weekend at the GLARC Toys 4 Tots race and ran RCGT. The track is 250'x100. We ran the whole track for 7 minutes. All i can say is the V 3.0 17.5's are awesome! I geared my Cyclone S 75/65. Yes, 65t pinion! You can imagine that lanes were wide open. Motor temp was 129*F. I do have a 40mm fan on the motor and i am running the 312 program as well. I did not play with the timing...i really don't need to. Especially with the super tall gearing, you want to keep the motors as cool as possible. I don't recommend gearing this motor this high in any track smaller. This was geared just for the long 250' straight.
