Jeremy, sorry to hear Dave is giving up

Enricong, Allright, way to go, glad to hear you got her going, Oh man I forgot to post the pics
I was working on covering a T-38 Talon I built. Let me ask you this, your turning left prob, does the left wing tip hang down or is it listing to the left, here's a couple ways to check for the cause, remove you LG of find a way to sit it flat on it's belly with the wing on lay a level on top of the wingand see if shes level, if not it is possible that what you have is a very slight twist in the fuse
also look at your tail from the rear and make sure it is perfectly level with the wing. also make sure you rudder stab is not twisted, it doesn't take much to effect flight, if you trim it right to get it to fly straight how does the plane look in flight, does it look like it's walking sideways. and finaly while it's sitting on it's belly measure from the wing tip to the suface it's on, your dehydrial might be off on one side, if none of the above is found to be wrong try taping a penny under the right side of the wingand see what happens. Good luck, I hope you get it straightend out
