I purchased a new Spektrum DX7 about 2 months ago. One of the great pilots at that club said Spektrum receivers have a problem, momentary rebooting, which takes about 2-4 seconds. That's a lifetime in seconds. No control, and 2 guys hit the ground, and one survived. We are talking a 2 thousand dollar aircraft, at a 350 to 400 doller radio system.
I called my local hobby shop, and discussed this problem. His answer was turn on the TX, then the RX, then unplug the Battery or switch it to off, immediatly turn the receiver back on, If you get the orange lights with not hesitation, it's ok, if they flutter then go on, they need to be sent back to Horizon Hobbies. They will check the receiver, and do a firmware update, with a quick recovery??????????? Why , now all of a sudden is this happening.???

So, if you take the time to pack up all the receivers, and wait for 4 weeks, that's ok. My friend asked the question, "Why did they not have this checked out beforehand?" What would happen in a real aircraft????????
If you or your friends have Spektrum Radio's beware.
We need some input on this problem. Thank You
