I'm running the 21.5 SP5 in a touring car on carpet with FD at 3.64. Fairly small track. The other cars seem to have higher top speed with 3.8FD/Trinity Slot Machine. Would you suggest dropping down since this is a torque motor?
I have experienced this where I have actually lowered my FDR and gotten faster. One case was with the Fantom Icon in 17.5T some time ago. I would say try two teeth.
@@telecomandorc This worked thank you! Actually ended up adding 4 teeth to the pinion (3.36) and got within 4 tenths of the fastest lap. I think 3 teeth (3.42) would have been perfect but I didn't have the parts. I know the timing marks on the motor are just a reference, out of the box it reads 40 degrees. When you were testing the SP5, did you find the factory timing was close to 40 degrees on your analyzer?
@@telecomandorc NORA On Road Carpet Racers in Washington State made a public statement on it yesterday. It is legal at club events until our ROAR regional in January. At that point it will be considered illegal. Seattle RC Racers has yet to make a public statement but I think they will follow suit with what NORA is doing. It is a popular motor in this region, its a shame to see the brunt of this mistake being put on the club racers shoulders. Alot of hundred dollar paper weights to be delt. Maybe the bashers could find some cheap speed if they hang around the track long enough.
A bit of a newbie question. Would you prefer a higher torque motor for a high traction track and a high rev motor for lower traction with 2 wheel drive off-road? Back in the day we raced on dirt with brushed motors. I'm back in the hobby and everything is carpet.
great info and cool analyzer
Thank you. I should have another one done soon. I hope I can get some time this weekends.
Looks like they're still wanting to dampen the pinion side of the motor.
Replaced the small rubber o-ring with a spring washer. Pretty nice
That almost seems like a friction point. I may just go nylon on this.

@@forensic_ttv9503 Very nice. Side question, is your track keeping Trinity motors active since they were dropped by ROAR recently?

Pretty much. You are spot on, I would say. Carpet has high enough traction to handle the torque and take off. On low traction, not so much.
