Need a little hand holding here.
I’m building a quad tilt-wing. I’ve flown the frame as a quad, using Copter. I have the latest Plane installed now and the Q functions enabled. What I’m running into is kinda strange.
First thing is I don’t have the wings installed due a 3D printer malfunction, so waiting to get that back to fabricate the wing sections. I haven’t flown it in any of the Q modes yet.
My present flight modes, on 2 separate Taranis switches using “replace”, are:
The tilt servo is on Pixhawk 2.1 Servo9.
On the bench, no props and disarmed, I can get the motors to tilt from vertical to horizontal in both Manual and FBWA. If I arm the frame, Manual gets me full down tilt but FBWA does not. FBWA will twitch the tilt servo but nothing more. The odd thing is if I add THR, the tilt servo starts following it, so that at full THR, the motors are horizontal. Let up on the THR and the motors move back vertical.
The other oddity here is if I flip in and out of Manual while the other Taranis switch is in FBWA, the motors will go full down and stay there.
I’ve read about and changed the Tilt_Assist and Q_Tilt-Max functions, etc. along with the “Arspd” parameters and nothing seems to get the motors to tilt when armed and in FBWA. I’ve even used compressed air to simulate air speed thinking that param needed to see something. Nothing changes Re FBWA.
Also, being new to Arduplane in general, I am unable to get a Taranis radio off failsafe to work. I can invoke a manual F/S and the flight changes to QRTL. I’ve set the Taranis custom F/S to the same value but Mission Planner shows me the last flight mode before turning off the radio. Kinda nervous about flying in that situation.
-Frame and arms are Home Depot square 15x15mm aluminum towel bar and Actobotics U channel and bearings
- 2.1 Pixhawk
-Sunnysky X4108S 480KV motors
-Hobby King CF 15x5.5 props
-Lumenier 4 in 1 35A ESC/PDB
-Gopro on a gimbal
-Old DJI F550 gear struts
When I get the printer back, print up wing ribs and skin with 1/32" balsa, using the square arm tubes as the spar with additional 5x5mm CF tube as secondary. There will be a total of 8 wing sections 2 each per arm in and outside the motors. Aerodynamic controls will be ailerons on the outer front panels and elevators on the inner rear panels. Rudder mounted aft. Wing span looks like 42-48" x 2.
Any thoughts are appreciated.
