i just bought an mx 400 (i think its similar to the trex)kit . i have only flown a blade cp before. i need some ideas on what i should put in for electronics. i know theres a million choices but there must be some tried and true methods.i will be using a futaba 7 channel tx i need to get everything else.im looking for some stuff that will work with out too much modifying.servos reciever gyro and motor. thanks for any help

The high end combo would be 401/9650 for the gyro, hitec 65 metal gear for the cyclic servos, medussa 3400 for the motor, and Jazz esc. Since you have a futaba I would go with the 146 pcm receiver. Theese all fit in the t-rex so I will assume they will fit in the mx pro. You could save some money by not getting the Jazz esc they are expensive. Other esc that are popular: cc35, quark 33, and the align 35. I would go with the tp 2200's or the evo flight power for your Lipos.
