Hello, I'm getting parts in this week to rebuild my 450DFC. The motor arrived today :banana: The esc, main blade, tail fins/blades, main gear and canopy should follow. The motor is an Align 460MX/3200Kv :wiggle:. I was running a Tarot 3500Kv motor with a 9T pinion with HW50a esc on the 450. I loved that ratio but With the 3200Kv, same esc, what tooth count should I start out with? I'm leaning toward 12T. The main gear is the 121T slanted. Thanks in advance.
