Help!
Trying to find a gearbox to fit this motor

I have a Black Mantis BM3650 900kv inrunner motor that I would like to find a gearbox for. I would prefer to not go into why, but if anyone has any advice on specific gearboxes to use, I would very much appreciate it!

It has a 36 mm canister and a 3.17 mm x 15 mm shaft.

More info here:

Thanks!

That's just too vague and open ended a question.

What sort of gear ratio are you looking for, and how much power are you expecting to put through it? You also need to specify the mount pattern on the front of the motor casing, ie 4 x 25mm PCD, or 4 x19, or 2x16 + 2x19. You also need to address any other constraints such as whether there is a boss on the front of the motor that might affect gearbox mounting, whether offset is feasible or inline/planetary is required. Is there a gearbox output shaft constraint?

Why the secrecy? - you're basically asking folks to provide you info on gearboxes when the solutions offered may be entirely inappropriate, thus wasting their time.

Any gearbox designed for a 'Speed 600' or '540' motor should fit, eg:-

I agree with Scirocco...Gearbox choice depends on what power output you want and what size prop you intend to fly with.
