The RC world is changin' (OMG pinions!)
#17
I have a 65 pinion and 76 spur, I run a 56 with an 80 spur on my small indoor track.
#18
guys at snowbirds were trying to run 65 pinion to 65 pinion (on top shaft) at the 'Birds in the sprint class. We'll be seeing more gear reduction in the molded case transmissions soon. i would not be surprised to see a jump to the 4.x range that Associated and Losi (and probably others) already offer in their gas trucks. Just takes a slightly different tranny case mold. somebody will figure it out for the road cars also.

The problem is, the spec motors (10.5, 13.5, 17.5 etc) are of different construction and type to the modified brushless motors. If the companies had stuck with the same format for the spec motors as the modifieds, there wouldn't be this ridiculous gearing. There are ways to make a 17.5 motor rev much higher and not produce much, if any, more power. This is what may eventually happen for these classes to be realistic (especially 17.5 and 21.5).

cmon marcos, we're not much different then f1. get every last bit of performance out of it. that is the nature of competition (and marketing!).

Hey Guys,
We have a few LARGE pinions listed already. We'll have more listed tonight and as the inventory arrives.
Cheers,

Well here is a stupid question ,why make slower motors (17.5/21.5) then make bigger pinions and smaller spurs to go as fast as the motors before(13.5)?
How's THAT for an answer?

If 1:1 gear ratios are the answer might was well just bolt a wheel to the motor.
All to silly, just bump down the voltage and run a proper motor that rev's higher than 5rpm.

I guess the touring and on road side is catching up to the oval side. We've had PRS pinions all the up to 65tooth for a while. It's all about speed with the slow motors.
