to swap over the Supercub to spektrum you'll need 2 servos and a ESC. the factory radio gear that comes with it uses 5 wire servos and the ESC is built into the RX. you can get a cheap ESC and use the stock plug off the hobbyzone RX/ESC. I'm not sure if the LP cub has the mini tamaya connectors like the regular supercub or if it has the blue ES3(I think thats what they are) connectors like the other PZ planes
