mrtube Posted March 8, 2009 Posted March 8, 2009 Hi, I am posting a link to a track, where I am struggling to understand what is happening. i have just taken off, I stabilise in a hover, i am not in route mode, and i have the heading hold button off, just pitch and bank buttons on. I input rudder to point to my desired heading, when i get there i release the rudder, but the helo, slowly goes back round the other way and will then carry on turning slowly round. If you look on the track, you can see me make several attempts to stop this, as soon as I centre the rudders, it starts again. Why is this ? http://www.2shared.com/file/5032857/79799285/rudder_problem.html My rig: Asus P6D, watercooled, Intel i7920 cpu O/C to 4GHz, 6GB Mushkin redline PC3 DDR3 1800MHz memory, BFG TECH gtx 295 GPU.

asparagin Posted March 8, 2009 Posted March 8, 2009 you must fly with the trim. 1. make rudder manuver 2.press trim 3.quickly return to center position (if you turn with joystick) then the heli will stay at the heading you want. check also other posts on trimming and rudder: there is a good and a bad side.

Why is this ? http://www.2shared.com/file/5032857/79799285/rudder_problem.html It's because you have "Heading Hold" off. I think when this is off you are subject to influence from the wind or some other mechanical force. Heading Hold compensates for these and locks you in the direction you want to be going, but you have to trim if you want to change direction. I reckon this is a good example of why its good to keep the Blue button autopilot channels on. With them off your having to compensate all the time with the pedals/ stick. Like in Il2 when the torque of a plane keeps pulling you to one side so you have to constantly input rudder to counter it, or use the airplane's trim.

Like in Il2 when the torque of a plane keeps pulling you to one side so you have to constantly input rudder to counter it, or use the airplane's trim. This is a good explanation. You could have stayed in your stable hover without using the heading channel of the autopilot by using just a small amount of left pedal force. As you have now witnessed, hovering out of ground effect will require a bit of pedal, as centered pedals will put you in a permanent right turn.
