Radio from Quad

#1
A while back I bought a quad racer 280 RTF. In my opinion it was a nice little drone. It flew very well but had no auto controls like most seem to have now. Anyway, I flew it quite a few times and crashed it a lot. I replaced one motor but then another one died. I decided to just use the parts on other projects. So I took out the receiver and installed it on a test plane set up. I plugged in the servos to 1,2 and 4 and esc to 3 on receiver but couldn't get any response. Sticks had no control over servos or motor. Is this radio system set up for the quad only and not reconfigurable? There are no programming switches on the radio. I was hoping I could use this as a backup.

With a quad only one ESC supplies power, usually. Is it possible that your Rx is not supplying power to the servos on channels 1, 2 & 4. The test would be, see if the ESC can power the Rx on one of those channels. If it can, that blows my theory.

Yes the motor only powers up on channels 5 and 6.

So channels 1, 2 & 4 will not power the Rx, right? Then I’m guessing the positive pin on those channels is not connected. I’m guessing your servos will work, if you supply positive to them.
