Hi,

I bought a 2nd hand 450xl recently - 430LF motor
Had a 13 tooth pinion in it but looked quite worn, I received the 11 tooth with the heli as spare and have put that on, seems ok?

Was wondering - should I be using a 13 tooth instead and will an 11 make the motor run hotter or cooler ?
What differences can I expect to look for with an 11 tooth vs 13 tooth pinion.

any help appreciated...
