Hi. I'm new to the hobby and came here for help. I currently fly 4ch fp heli's. I just bought my first cp which happens to be a trex 450 v2. I got it from a friend who removed the direct drive from the tail and added a brushless tail motor and esc. I will be using a devo 7 and a walkera master cp six axis gyro receiver combo. Will this work or should I reassemble the tail back to original? Thanks for your input, because I'm clueless.
