I'm at my wits end!! Any help will be VERY MUCH appreciated.
Things I have changed and tested after each change with no results:
1) Level the APM to the center line of X8, re did all "Initial Setup" in MP
2) remove the end point on travel, was 80% now 100%, re-did all "Initial Setup" in MP
3)Changed firmware to V2.76 from V2.78b, and also re-did all "Initial Setup" in MP
4) I have also re-leveled the plane with a 5* pitch up, and still no success.
5) I did a ground check by double checking control surface movements.
a) manual mode..Pull stick back, both elevons go up. Pushed stick forward, both elevons go down. Stick right, right elevons go up, left elevons goes down. Stick left, left elevons go up, right goes down.
b) FBWA mode…. Put nose up both elevons goes down. Put nose down, both elevons go up. Banked to right, right elevon go down, left elevon goes up. Bank to left, left elevon goes down, right elevon goes up.
Every thing "Ground tests" great.
Still, no change, when going into FBWA or Mission, or RTL it will start descending and I have little control if any "Nudging". I have to go into "Manual"
I have almost no trim in MANUAL MODE, if any .....it would be 3mm (1/8") up. It is touch nose heavy.
