Default have car gear want to teach it to fly :)

Speed control will work but most car ESCs have BEC but not a low voltage cutoff. So you lose motor and radio at the same time, not a good idea in a plane.

As for motors, stock (27 turn) motors are used direct drive (in EFlight we call 'em Speed 600s but they're basically stock Mabuchi 550s), anything much less is better geared. If you're intending to stick to only 6 cells you might get away with going down to about 20 turns DD.

What sort of plane do you want to fly ? You could probably drive a 5-6 ft span glider or a trainer up to about 45-50 inch span or a warbird up to about 40 inch.

It will be the battery that's the problem. 6 heavyweight sub-C cells have trouble generating enough power to get themselves off the ground for any length of time.
