Spektrum AR8000... two bad receivers?

I purchased a DX8 that came with an AR8000 8-channel receiver. I'm trying to use it for an ArduCopter that was built by jdrones. The first AR8000 wouldn't power up even though it was receiving the correct current (4.95 volts) from the ArduCopter APM. So I went and purchased another one today and tried it out. It won't power up, either!

Is this common with Spektrum? I have read a lot of negative reviews and forum posts about trouble powering up and binding. Is there something I'm doing wrong?

@Aaron,

I have yet to have a bad Spektrum receiver and I have an AR8000 too. You do know that the receiver output pins are the reverse of earlier Spektrum receivers? The PWM signal used to be on the top side of the receiver, but on the AR8000 and newer Spektrum Receivers, it has been reversed with the PWM signal on the bottom of the receiver. Therefore the power connector black lead should be on the top side of the receiver where the channel legends are written.

Just a thought.

Wow, talk about egg on my face. I hadn't realized the new pin configuration and there really isn't much documentation from Spektrum on that. Thanks so much for the info! The AR8000 works like a charm now!

@Aaron,

Don't feel to badly as I did the same thing with my AR6115, but it did not hurt it electrically. It is interesting that Spektrum changed the pinout without really emphasizing that the newer receivers did not have the same pin configuration as earlier receivers.

By the way, I noticed that you live in Texas. I live just north of McKinney off of state highway 75.

Do you use the RX with satellite ? The AR8000 won't work without.
