So you can use a revo spur and it will connect with a pinion, not worried about gearing, i can get that. thanks, just wanted to know.
My current setup is using a 3096 Emaxx tranny w/gorillamaxx half tranny conversion and a strobe/51 mod-1 gearwith 20 tooth pinion, motor is a 1515/2.5d/f (1700kv) neu on 5s.
here is BrianG's calc of it

here is same pinion using E-mexx/revo (3095) with 40 (revo Mod-1) tooth spur

only 7 MPH difference, so i'll be close. thanks for the info.
if it becomes an issue of power, i can drop a 2250/10t in it, that'll pull any gear i want
Work because i gotta, play because i wanna
People here hate Nitro, I love it. I start it, run it about 50 ft from me and it dies, I go after it. Perfect exercise
