Someone mentioned Spektrum has a policy if you crash due to Rx failure you can send it in for inspection.
I've had an AR6200 cause 2 crashes. I'm certain it was the RX. 2 different helicopters, same symptoms. Total lockout for about 4 seconds then it recovers. 2nd heli caused about $100 in damage. All within 30' of me.

It's not exactly "crash inspection service".

It's called, "I think my RX is bad, I'll send it back to Horizon Service Center for repair".

About what you would do with any electronics under warranty that you think might be bad.

Unfortunatly, I unplugged it right away. I heard a buzzing thinking it was the motor running (teeth were torn up on the maingear)and did not want the blades to engage while I was picking it up. Turned out it was the motors on the servos that had the broken gears buzzing.

Did you happen to read my thread here?
https://rc.runryder.com/t579772p1/

I had 2 crashes that I suspect were caused by my radio equipment. The first crash, I unplugged the battery but I didn't notice any blinking lights. The 2nd crash, the lights were solid. So it wasn't a power issue. Both crashes felt exactly the same (total loss of control, no response to input) at near the same distance from me, about 350 to 400 ft or something like that.

Just read your thread. Did you send it back yet?

Incidently, my Crash #1 was with another DX7. I purchased a backup DX7. So I know it's the Rx.

I had a crash on an AR6100 then an AR7000 and got another TX. Turned out the AR6100 crash was the servos were bad and the AR7000 was the Rx battery was bad due to a failed Landing gear setup that drained the battery.

I haven't sent it back yet. I'm using it to test out my rebuild and for Phoenix sim. I ordered another radio (Futaba 8FG and 8-ch. rx) which should be delivered by Monday. Then I'll send it back and also range test the Futaba under the same conditions which I tested the DX7 and AR6200. I'm curious if it will suffer from the same issue. I don't want to try my 2nd rebuild on the same DX7 gear. I already spent $350 in repairs across those 2 crashes. Here's another thread where I give more details on my 2 crashes.

Please post your results with the Futaba equipment. I'll be surprised if it fails to range test well.

Some new info on my particular situation.
I was rebuilding my 500 and found the servo connector at the end of the UBEC was faulty. I recrimped a new one and it is fine now.
I knew it was faulty when I rebound the AR7000 and it kept resetting on me every time I moved it.

It just so happened that the BEC in question was on my other 500 when it crashed and was removed when I put a CC ICE on that 500.

I'm going to give the AR6200 another chance in a 450 heli and fly it as much as I can in the next 2 weeks to validate what I found today.

BTW, the only time I had issues on range testing Spektrum Rx's was when my heli was sitting all the way on the ground like a 450 and I was at my grass field. Move it up to the height of say a plank antenna would be off the ground and there is a world of difference. Wet tall grass I have found also affects the results of ground testing.
