Quick question on binding, Spektrum...

[Beavis]

Hi. Sort of a noobish question.

I've been flying for a few months now. TX: DXe. RX: AR400.

Is it critical that the bind plug is pulled right after binding? I never figured it was a big deal. But I've had several crashes where there was an apparent loss of control (starting a bank turn, then it never recovers). I thought I might have a bad rx. Today while flying my Scout I had a blackout, causing it to plunge. Control came back just before crashing, and I was able to mostly pull out before a hard landing.

My power pod ripped, so I had to do a quick repair. When I rebound, I pulled the bind plug, and never had a problem through 2 whole batteries.

Is there some known science to this, where I was just slow on the uptake?

Thanks!

After binding unhook power ALWAYS pull bind plug I like to turn off the transmitter and then turn everything on. If the bind plug is not pulled it puts the receiver into bind mode every time power is hooked up.

Thanks, I will make sure to continue this. I guess it leaves the rx open to binding with another signal?

The park where I fly has a big cell tower at the end of it. I wonder if that can cause periodic blackouts?

Yes especially since the receiver was in bind mode.

absolutely an issue and cause for serious concern! one of my close-by "air fields" is a very large bowling alley parking lot with a cell tower at one end. i've flown there for the last few years and finally one early morning (2 months ago) my ship (umx radian) got hit hard within the first minute of flight at about 200' up, lost all control, she flew off into the sunrise, finally spiralled down into the ground a few hundred yards away. radio gear was intact and tested just fine. the invisible cell tower monster strikes again!

Well, I bought a couple of 6 channel Lemon rx's for this plane and other projects, and to see if I was having receiver issues. After binding and pulling the plug, the tx now binds with the rx instantly with every power up, no plug needed. I guess I wasn't sure exactly how all this works, but now I am learning.

Took the Scout out this morning, and only had a brief moment of ??? down at the end of the park with the cell tower. I quickly recovered, and didn't have any more hiccups. With the price point on these Lemon rx's, I might buy a couple more to avoid swapping out receivers between planes.

Thanks for all of the help. I am really starting to enjoy things as I become more comfortable with the tech. Maybe soon I will un-ground my Eflite P47.
