How fast do you think you'll progress? If you think you'll be flying the new bird in 6 months leave it as is and don't use anything but the transmitter. If you think it'll be longer use the Gyro, maybe the servos. You'll really not need the GV1. If you touch the servos make sure you take pictures, diagrams, etc for the cable routing and leave the servo wheels in the Fury hooked up so you don't have to remember the holes and stuff.
