Autopilot sways off course

This has been a pain in my ass ever since I bought the module and this is why I don't use autopilot and have to fly 20 minute flights myself. When you set your autopilot to level flight it doesn't manage to stay on course. It seems that it either doesn't apply rudder at all or applies it not enough and the helicopter goes into a slight right turn. I see the mechanic as giving controls to the second pilot, so I would assume he is capable of looking at the instruments and staying aligned with the right numbers. Also, the transition to autopilot seems a little bit too agressive. Every time i'm afraid of the rotor jumping off from snaplike collective movement or engine stalling from low rpm.

It was not intended to be an autopilot that will fly for you. It was more of a momentary help, while you look at the map, or change frequency. I know about this tendeny, so I go left of required heading before giving him control. It works for quick trip to the loo or to get some snack

I don't know what it was intended for, but right now it looks exactly like a bug. If it was momentary, they could make it disconnect after a certain time. It can precisely fly at an altitude but can't follow a number on the compass

P.S. Expecting a 2-pilot helicopter to have a fully functional autopilot in the absence of a second player is fine by me. Taking into account that this helicopter is so bareboned that it's physically demanding to fly even 20 miles. Especially since the pilots alternate in real life, and the second pilot should be just as qualified, so I don't see the issue

 I always end up flying it for so long on the search and recue server that I run out of fuel...

"has it really been 2 hours???"

 the fix you are looking for is not "autopilot" 

its removing the centre return spring from your joystick.

or if you don't want to do that then trim, trim, trim.

both remove the physically demanding fight with the centre return spring. As helicopters don't have return springs.

Yeah, I too was wondering about that physically demanding part? I believe he means it's hard to trim it so it will fly itself. While that might be so, I remember one instance where my pilot got killed, but helicopter kept flying. I waited to see how long before it crashed. After 10 minutes I got bored and bailed out.

Still not my point. I use trimming, so spring is fine, but you still need to keep your hand on stick and throttle at all times. You don't really in real life, you can just pass it onto your friend to the right for 10 minutes. If it looks like a bug, swims like a bug and quacks like a bug then it is a bug. At least I think that it does, you notice how the helicopter starts turning right every time, with the same amount of turn. I think they just need to tune it better

I agree with you, @Mivina. It needs to be fixed. The argument "it's not an autopilot, it's intended to simulate a co-pilot" doesn't mean it shouldn't be able to keep a compass heading. A real copilot would be able to.

Found this when I was playing around with the output through export.lua

 

With the AI co-pilot holding level flight (AP on):

 

arg(133) [slip indicator] value = average .0051

arg(142) [roll] value = -.0002

 

Doing some manual testing (AP on/off), .0051 for the gauge on the slip indicator value causes a lot of heading/track drift over 10 nm.  With AP on, the co-pilot just holds a positive slip, there is drift in the value over long periods of time, but it is not what you would expect if you were modeling a human pilot.  This seems to be a bug, it just doesn't reference 0 slip or ever get close enough to maintain track/ trim flight (min value observed: .0047)
