8mm Shaft MOD 1.5 M1.5 Pinion Gear for FG/HPI/Losi & More (24T)

I bought this for a rovan 5b electric conversion. It fits the conversion as long as you use a 54t spur. Cant run 21/57 not enough adjustability on the motor plate unless you mill the slots longer.

Fits my hobby rocket motor in my arrma kraton 6s that is now 8s
