Back to the drawing-board... I've recorded several starts to see if I can see something different when it fails and when it doesn't. I'll report back once I have something more solid.

I think I have found it.. I've finally managed to reproduce it consistenly (but haven't been able to have it tested by anyone else yet). It seems to happen if you enable the avionics too soon after enabling external power. (Basically I've been an impatient idiot...) Try the following: Turn batteries L+R to ON Turn on Avionics L Connect the GPU Enable External Power This is just to make sure that the avionics are enabled before the aircraft finishes switching power to the external supply. The throttle should be "walking" forward continually. If you do Turn batteries L+R to ON Connect the GPU Enable External Power Wait until all the annunciator lamps above the battery switches to finish switching to the external power supply Turn on Avionics L Then everything works as expected, no movement of the throttle.

...aaaand the problem is back again... I've done some testing, and it seems to be tied to the AC power and avionics. I turn on batteries: OK I enable external power: OK I enable any one (or multiple) avionics system: Walking throttles... I disable avionics: OK again I turn off external power: OK I turn on avionics: OK I enable external power: Walking throttles... I disable external power: OK again I start the Left engine (with GPU removed): OK I reset the left generator: Walking throttles... So as soon as I have avionics on and AC power, something happens to make things mess up again. I reinstalled the 340A and still no good, even though it worked fine for a few days. I've had so much fun with this bird, so I'm really frustrated that I have to find a fix for this again, especially since I don't really know what triggered whatever to make it start working again last time. :/

Ah, excellent! I don't really know what I did differently, but I set the throttles up using "THROTTLE 1+2", and they now work as intended! Took the bird up for a spin, and I love it! Need to figure out the autopilot in both VOR-mode and GPS-mode now.

I got the 340 yesterday, and after pulling my hair out trying to map various controls on my Logitech Yoke (why do I have to map power levers to REVERSE 1+2?), every time I get both engines started, the power levers just move full forward constantly. I can jiggle my levers, the levers in the cockpit sync up, and then start moving again. It only stops when I shut both engines down. Any thoughts on what's wrong and what I can do to fix it? It's unflyable at this point. And I have tried to reload the aircraft, reinstall, restart X-Plane, but nothing helps. :/
