Hey guys I had a crash this morning that I thought was the fault of one of my emax servos but come to find out it was my left right yaw control on my dx6i. I went into the monitor and saw no movement when I moved the stick. my question is that since I have had my radio I put a turnigy backlight display in it and had to replace my throttle hold switch that I broke with one I got from radio shack. If I sent this radio to Horizon hobby do you think they would work on it or send it back to me and refuse because I tampered with it. Also if I have to buy a new radio what do you guys think about the Turnigy xr9 pro? I have 7 450 class helicopters that all have spectrum receivers on them. Would I have to change my receivers if I went with that radio?
