Silly Question: X-Plane 10 PT-60 Pulling to the left

Hi All,

Fairly new to all of this and got my APM 2.5 last week, Keen to test it out I fired up HIL Sim + X-Plane 10 and was having major problems with control, After reading all I could and resetting everything many times along with calibrations etc etc I pull MP and APM out of the loop.

Surprise Surprise It looks like X-Plane 10, Just removing the brakes on the ground causes the PT-60 to pull HARD to the left under 0.030 reported power. Now I understand there is some pull from the forces of the prop but this seems.... odd. Is this legit or an issue? I'm having a hard time with the PT-60 pram file in MP getting it off the ground and in flight I see a salaom type path between way points.

I get the feeling this is going to be something simple or silly I just haven't done but I'm out of ideas right now

  • I'm not understanding this either... the very strong pull to the left... and a slalom (snake path) path in Auto mode... its like its trimmed roll and yaw to the left.  It's not the propeller effect. as you can try the modeled jets and they do it as well.

    I've tried a full reset, reset all the parameters, tried other parameters.

  • Hi -- try one of the param file I have attached.

    Take off in manual -- get it level.  Then switch to stabilize, and see how it works.

    If good, put the airplane back on the ground, set a few simple waypoints in the

    flight planner, take off in manual, get it level, and then switch to auto.  Click 

    the "restart mission" button and the auto button (again) in the flight data / actions screen.

    Good luck!
