Hi there I am new in this forum and I have bulit a Tailsitter Caipirinha2 with non vectored dual motor setup.
I am playing around with arduplane,copter,and traditional heli. the last 6 years.
I read nearly all of this discussion here an tested a lot (crashed about 12 times) -
May elevons are about 1/3 of the wing as recommended. Now I exteded the servo throw.
The Plane flies acceptable in the ‘wing’ modus FBWA - but in qstabelize and qhoverI have the following problem:
The hovering is quite stable until a light wind blows or I lean more than 30 degrees to the back or the front.
If this starts …the motors are accelerating- and the plane starts to climb and wants to fly !!! I once hat that issue - switched to fbwa and then flew a round …but It should hover until I flick the switch to fbwa not before.
Now I examined the logfile and the throw of the elevons when starting to lean in either direction are max 45 degrees - although the physically move could be 60 degrees (for example in acro or man mode).
My question now is: which parameter determins the max elevon lean angle ? I went through the Q_ and Q-A parameters many times but could not find a solution.
Maybe one could help me
to My person : I am from Germany, just turned 50, and build about 8 drones, 2 helicopters, 2 planes and now the tailsitter came from the very beginning of apm 2.5 now to pixhawk mini micro and pixracer(like the wlan configuration via ipad )
Thanx for your help in advance ,
