I just recieved a tqi radio to put in my electric rustler and it seemed to work okay. I tried to do a speed run and once I got to full throttle, I lost all control and it missed my mailbox by an inch. When I went over to it, the servo was as if I was turning. When I lifted the front o the truck up, the servo recentered and I was able to run again as usual until it happened again. I am frustrated because I got the tqi to replace my glitching and interference-prone 27mhz radio. They are fresh batteries, so I don't know what else the problem could be. Anybody have any ideas of what the problem could be?
