I recently purchased a Runner 250 Pro and I cannot get this bird to fly. I power on my Devo 7 and immediately plug in the battery on the 250 Pro. The left rear red LED flashes about 4 or 5 times and then starts alternating with the right rear red LED... back and forth. I taken the advice I've read about and just gave it time but unfortunately no amount of time waiting seems to solve the problem. . At about 6-8 minutes it starts beeping and the motors start twitching in addition to alternately flashing rear red LEDs. This is as far as I can get. Either the IMU heating process is failing, or it's failing to bind with the Devo 7, or both? I've tried 20+ times inside, outside, in the wilderness far away from any interference. I'm at a total loss. Any advice would be greatly appreciated!
