Well guys, the very thing that I was trying to avoid just happened, on my second flight today I had a fail safe shutdown, I could hear the engine spooling down, then nothing....the Boomer was in an excellent position for a runway landing, it made it just fine to the runway.
I was flying with the antenna on a horizontal position for the first time ever and I got into the failsafe, flying with the antenna in the semi-vertical position has never given me any problems.
Never, ever before any of my receivers have gone into failsafe mode, I will be testing the radio with my foamy then with one of my small nitro gas airplanes, if I loose one of those, no biggie.
