Hi wsx x

Welcome to the forum firstly.

Can you tell us what motors they are (size, brush(2 wire), brushless( 3 wires) and type and size props please.

If you can add a few photos would help.

Yes you can use Lipo's on both types of motors.

Regards

Harry Smith

X: I think once you log on there may be a "create album" box somewhere.

As you have brushed motors, you can use one speed controller, wire the motors in parallel and not series, so each gets the same voltage.

We would need to know the make of motor to advise on likely type and capacity (in amps) of speed controller, also some motors are not suited to 11V. If props have been fitted we would need to know the type and size of them.
