RE: That's it, I'm selling, I hate the cp pro.
If you're going to get a Trex, then you'll need a computer radio. Try it in your BCPP. It makes a huge difference to have a programmable radio and decent servos. I got mine to where it was a pleasure to fly with the DX7. I think subtrim, which allows proper swash setup and the ability to run a proper throttle curve make the most difference.
I agree that the BCPP is a poor choice for a trainer.
