From the OP's description of his problem, I highly doubt he had a power problem.<div></div><div>Problemoccurredat the exact same spot, twice.
I don't think so, not that what you are saying can't happen....

I've had the same issues as him with the same "Orange" RX he tried. This with the plane no further than 40' to one side of me.
The plane was well within the donut.

The "Orange" RX seems to have been more sensitive to such problems than the Spektrum.
OpJose, Ihad the exact same issue with TWOspektrum 6200 (original)receiver as well. In fact Isent it back to Horizon hobby and they replaced it with a AR7000 and an AR600 after claiming there was nothing wrong with the reciever.
The two most compelling pieces of evidence are :

1. In both cases, the antenna was pointed straight at the plane (I wish Iwere a bit more aware about radio wave propagation shame on me!) and (2) in both cases the receiver was using a 4.8 volt 1500 mah battery (I could swear Icharged them well each time) but your point about amp draw is well taken.

In the latest crash the plane went out of control, came back into control and went out of control again. It appears to have something to do with radio signal OR(less convincingly)about battery. I'll say in the Orange's defence that this is the first such incident after many flights. ( However, one is enough! ) Three incidents are enough to start me wondering about the Spektrum Technology itself although Iam more inclined to beleieve it was my fault if others are having good luck with it.






I can reproduce the reboot/loss of control easily if I use a low capacity &amp; voltage battery pack. It mimics what he and I both saw.


From the looks of it would it suffice to test your battery with a two amp current draw (for how long?) ? Is that being too conservative?Is there a ball park number one can use to test out before going airborne?

(P.S. My inveterate son flies these things Iam his builder, chief financial provider, cheering squad and chief mechanic. although Ihave been making attempts at flying myself and starting to enjoy it tremendously. )
