Could you please expand on tail rotor setup?
The wiki page I’ve been pouring over is pretty short and for a first time setup leaves out some things. I’ve been looking at this post and this post and they suggest some different initial setups.
It would be good to clarify when does one need H_COL2YAW? Is this for “UAV” flying or for aerobatic? (the posts above suggest aerobatic, but that is all pre version 4.4)
The threads I linked above suggest that setting the tail rotor pitch to neutral and let the PID loop do the rest is enough. The wiki suggests setting tail rotor pitch (SERVOx_TRIM) to the value needed for hover. What is the current accepted wisdom with newer versions of AC?
Also, on the topic of tail rotors: A comment somewhere on Narrow Band Servos would be handy. In all the airplanes I’ve built I’ve never run into one of these but I guess they’re a thing in helicopters? A search of the forum here shows me the use of these servos is a bit contested and there are various opinions. I’m not too worried about that. What I know is the OMP M4 kit includes one of these servos and MP doesn’t let you just drop the SERVOx_MIN/MAX values that low in the configuration tab until you go into the full parameter list. Not a big deal, but wasted a lot of time on that teachable moment.
