joebecerra1947,

I never had to separate or even loosen the frame to replace the main motor (3 times, ughhh).

Unsolder it, remove the heatsink and you can "wiggle" it out.

Heatsink compound can be bought at Radio Shack or found on-line.


smoke157,

So when you move either Tx stick nothing happens?

Is the left stick's vertical trim slider all the way down?
This might cause a main ESC arming issue but the right stick should move the swash servos regardless.

Does the Tx have it's crystal installed, are they the same channel # in the Tx and Rx?

The green light on the 3 in 1 should flash for a couple of secs. and then stay on.
That is gyro initialiation but may give other clues.

The orange wire is the speed signal from the Rx to the tail motor ESC.
I don't recall which pin it goes on but if you didn't get the manual with the heli it is on-line.

We can't assume much when dealing with a used purchase.

Pilotlight????

Edit for spelling.
