I just installed a 9x system in my glider. Removed an old Futaba FM system that was working properly. After binding the rx everything worked fine except the throttle. Motor won't arm. I feel like it's a tx issue as both my old Futaba as well as a DX7i worked fine. I think I have something amiss with the tx as the rudder and ele work fine. I'm getting a complex set of beeps from the esc but don't know enough about esc's nor do I have documentation that tells me how to decode the beeps. Kinda think it's a throttle stick position issue but it's down with trim as well. So therefore I kinda think it's in the 9x tx setup and programming. I'm having a tough time understanding the online manuals for the 9x. Any ideas?
Went to the flying field today and finally figured it out. You were right of course, had to set both end points of the throttle and it saw it. I did find I needed to reverse the throttle in the radio setup and then it all worked fine.
Tossed the plane in the air and it all did wonderfully. Back on the ground and made adjustments with D/R and Expo and tossed it again. Had fun till storm clouds got too close and had to call it a day.
