After getting my trex i havnt flown my cp pro at all, plus the dd tail that was on it finally burned out after a ton of flight so there it sat for several months. I recently crashed the trex and was waiting for parts so i put a new gws dd motor in and did the ics50 esc mod for the tail that eliminates the 3-1. It flies very well now, even after having been crashed a lot and with a few dings in the blades. Im almost afraid to fly it thought because i know if i do crash it, i will never fix it again...maybe i should just sell it now and save the hassel...but then what will i fly if my trex is down for repair...choices choices.
