This is my first electric so I need a little help. I just started putting together the E-flight Ultimate tonight. Tommorrow I am going to get the new motor and all the electrics for it. I am planning on getting the new E-flight Hacker 4200 for it. Can I use the gearbox that comes with it or do I need a different one? Also what prop would you recommend for it? I am also getting the CC 25 amp speed controller, GWS 4 channel rcvr, Pico servos, and Thunder Power lipo's. Are these good choices?

Thanks for the help,

Keith
