This to me means it's not very far away from trimmed. In that case, why not attach a short bungee to the front of one side of the seat, and a jam-cleat to the stick (up a few inches). Then when it's two- up, pull the bungee to the jam-cleat and jam it. It is easily re-adjusted until comfy. When solo, release and pull harder and jam. Yes, it'll fly a touch sideways but if not far from trimmed then it won't be an efficiency problem. I flew a DC9 for several years and then found the starboard wing was 8 inches shorter than the port. It sat right in the middle of the fleet consumption curves.....

Voucher in Pilot - 1200ish. Another place up that way with a voucher is Netherthorpe. I've never been there and it looks a bit tight. Could anyone based there, or who knows it well, comment as to its suitability for a future DOTH?

You say it has an "irritating left turn". It seems you have decided it is primarily aileron/flap (roll) and not a yaw problem, right? What do you have to do to get it "trimmed out cruising straight and level", aileron or rudder or both? If both, which is most effective? Since you have put 29 hrs on so far, have you lived with this for this time or is it an increasing problem? Is the problem consistent with flaps up or down? As mentioned in this thread, a slightly deployed left flap should make you turn right not left, so this wouldn't seem to be the problem or at least not the only problem. Slight adjustments can be made at the flap hinge bolts connecting to the wing, but keep the inboard flap pivot bolt in close alignment with the hinge under the fuse. Slightly more adjustment can be achieved by off setting hinge to wing and re-drilling for 1/4" bolt. When on the ground can the ailerons and flaps be put in the correct alignment? It's not likely to be the ailerons creating roll as you should be able to neutralize roll at the stick. Unless you have a wing leveling servo that's interfering. Does the plane stall level or not? This probably will include as Fred Klein says, taking it back in the shop and do all the trim set up and measurements again. Is the angle of incidence equal? Hopefully the wing washout is right as that would be hard to change. Check measurement from leading edge wing tip to some point on centerline as far aft as possible. Hope this helps. Good luck finding the problem.

Is this to keep the plane from a slight turning to the right? Is the right wing low wi thout rudder ? - The next time you fly, do this for me. Once in normal cruse, take your feet off the rudder pedals. Use your stick to level the plane, then observe whe re the sticks position is. Is it to the left of center or is it to the righ of center, or does it remain centered ? In this position of wings level, w here is the ball? Is it to the right, or to the left, or is it centered? - The monowheel-does have-a tendenancy to turn left a little, when flown solo. - Jim Brown --- On Fri, 3/6/09, Kevin Klinefelter wrote: From: Kevin Klinefelter Subject: Re: Europa-List: Flap position, Flight testing Jim, In cruise I have to hold a little left rudder...
