Hi again, been some time indeed
Holger, have a look with channels at different positions. For example, set throttle to minimum, CH5 centered, move right stick, look at the jitter.
Then set throttle to maximum, move right stick in the same way, jitter will be a bit different. If you have a switch on CH5, set that to 0, set throttle to 0 too, move the right stick towards the "low" side, there will be some jitter on CH6. Now set CH5 and throttle to 255 and move the right stick in the hiugh side region, some jitter reaches CH8. I managed to get some on CH10 too with certain values on CH6-8, don't remember exactly how.
The jitter amount and distribution really depends on the positions of all channels, although CH7 is indeed the most affected.
For now I simply moved the tilt control to another channel and set the manual control speed back to 60, where it's barely noticeable and not disturbing in video. But as we work with a buddy box for the camera operator we need to have tilt, zoom, shutter, yaw on channel numbers <=8, it gets tight...
And if anyone wonders, the reason for setting manual control speed to the fastest is because we programmed the buddy box TX to work in slew mode on the tilt channel for better movement smoothness. When the operator isn't there, I programmed a 1s delay on the mx20 with a flight phase to replicate the slowing down that's done by the FC with the default settings. So with trainer switch OFF -> flight phase ON, pilot has smoothed control, with trainer switch ON -> operator has camera control in slew mode with no delay
I'll check the PPM signal from the HoTT RX next time I go where the hexa is, I didn't have the scope with me yesterday when I found out the source of the problem.
Anyway, thanks for getting that back to Graupner, figured out here would be the best place to report as you have direct contacts
