How about a 2 motor push/pull setup with smaller props? Counter rotating to reduce torque. More available power for take off and then you can throttle back once airborne.

I believe you'll need new servos, receiver, and ESC. IIRC, the RTF receiver used 5 wire servos and had the ESC built in. It's worthwhile to replace the motor with a brushless unit and use lipo...

I have a Turnigy G110 195KV in a Hanger 9 Taylorcraft on 8S. LOTS of power! Mine swings a 22" prop so make sure you have room to swing a big enough prop to get the most out of the motor.

Most HV ESCs are OPTO. A battery or a UBEC is what's needed. Plug it in to any open servo slot on the receiver if the receiver doesn't have a dedicated batt slot.

That's not that large. You might be able to get by with smaller EDFs and lighter batteries. It depends on the performance you are looking for.

The red wire is the center wire on the small 3 wire lead. It provides 5v (typically) for the receiver and servos. If you have two ESCs you typically disconnect one of the red wires.
