Luckily, I had ordered a motor and motor mount several months ago for this eventuality. Last night I installed a Turnigy SK 3530 1400kv. Since the Supercub came with all-in-one receiver and brushed motor ESC, I had to add an external brushless ESC. I chose an old E-flite 30A that was left over from my first T-28, RIP. The only prop I had on hand that would be even close to approriate was a 9x6. With a 20c 2200 mAh battery it pulled 36.5A. A little high, but since I rarely fly full throttle for any amount of time I felt it would work until I puchase a more appropriate prop. I think a 10x5 or 10x4 might be a good choice.
As long as I had the airplane torn apart, I used the opportunity to add a water rudder. I had a very nice plastic water rudder left over from the set of coroplast floats I had purchased on E-bay for my old 0.40 gas trainer. While those floats and the gas aircraft are long gone (sold on craigslist), I held on to the water rudder since it looked like a nice piece of hardware. I cut a pocket into the left float for an old servo, used a left-over pushrod and clevis, and we're in business. I'm excited to see how it handles both in the water and in the air now.
