Thanks to you and to the others who replied. We figured it out at the field this afternoon.

The linkages and geometry were all just fine. The problem was that I had reversed the throttle servo in the wrong manner. (The location of the servo required it be reversed). I set the reverse using the "thrtl rev" menu setting rather than just reversing the channel 3 servo in what apparently is the "normal" manner. There is a separate menu tree to "thrtlrev" and the spot where you can reverse all of the servos as needed.

The way I had done it apparently locked out both the trim and the throttle cut functions.

As soon as we undid my reversal and set it up normally everything was fine.

The plane started, idled and cut off just fine.

Five minutes into the "re-maiden" flight, though, disaster struck. With the instructor flying the plane, straight and level, the firewall separated from the remainder of the fuselage. I'm posting a full account in another thread "Second Flight Disaster". At least it's a manufacturing defect. I would expect to have the plane replaced.

Thanks again.

Bob
