Thanks for getting back to me!
Things I've tried:
These were all done while stationary and with the hardware set up on a desk.
Initially, I checked the operation of the servos in Manual. I used the virtual joysticks on QGC to move the servos: the right one for moving the two elevators on the tail and the left one for moving the rudder. Throttle works as well, but was removed from the mixer since the glider has no propellers.
Next I checked that the two tail elevators would attempt to keep the glider stabilized (flat, no roll, no pitch). Placing the mode to Stabilized made the tail elevators attempt to correct the glider. Ex, pointing the nose down moved the elevators up and leaning the glider to the left (in a roll) would adjust the left elevator up and right elevator down.
I planned a short mission consisting of:
- Home - at current location, at current altitude
- Takeoff - a small distance away at relative to home altitude of 0
- Waypoint - a small distance away at relative to home altitude of 0
Then I armed and placed into Mission mode. The elevators attempted to keep the glider stabilized while the rudder did nothing. I turned the glider in the opposite direction of the location it was supposed to reach and still nothing.
Then I changed the gain parameters of yaw in hopes of raising the sensitivity of acceleration for the yaw. I ran around for a short time while watching the rudder. It would pin to one direction and stay, even while not running. It seemed very sporadic. However, leaning the glider as if in a roll would move the rudder servo.
Just recently I set everything up in a car and had someone drive around in hopes of providing acceleration and getting the yaw to function properly. Again it would move with the roll of the glider. The test/experiment had to end abruptly, so I wasn't able to try as many things as I planned.
I've added the log files for that test in the car along with the mixer file I'm using.
