As soon as the new motor arrived (thanks again Andy), I eagerly installed it, (minimum clearance, no binds) plugged it in, checked everything out and fired it up. Got about 1/8 of a rotation and then nothing. All servos and the tail motor function as expected.

So I do a resistance test on both the new and old motors to compare. The old motor tests like a diode - resistance in one direction, infinate in the other. I assume either a short or open motor winding.

The new motor gives me varying resistance in both directions - windings and capacitors looking good.

This leaves the all-in-one reciever/gyro etc. 0 volts coming out of the main motor lead at all stick positions.

So I'm wondering if the old motor shorting caused the electronics supplying voltage to the main motor to fail and if so, if this would be covered under warranty.

You are saying that you have a 4 in 1 or similar. What heli do you have? I assume that you have a motor driven tail rotor. dose the tail rotor spin up with throttle? If so just swap the plug so that the tail rotor is pluggd in to the main motor plug and see it the tail rotor spins up then. If it will not spin up than you have a burned out 4 in 1.
When I used to fly a Falcon 40 I had a 10 amp fuse in line from the motor to the 4 in 1 to prevent this problem.

does ur tail motor work? put it into the main motor and see how it goes.

The heli is an Eagle 50. The tail motor does not spin with throttle up.

but you know for sure that your tail motor works right? if yes then it's a receiver problem.

Tail spins with voltage applied yes. How do I go about getting a replacement receiver?

yadac123

what's your order number so I can issue rma and exchange you with a new receiver.

Order # sent in a PM, thanks Andy.
