See you at the weekend Tom
Bob - I'm running 10% differential (JR).
With regard to the aileron mod - I should have mentioned the nice people @ Krill have started doing this as standard! I've attached a photo of the hinge the wings come installed with.
With reference to the CG and thrust lines - I'm also running 3 degrees of side thrust and 1 degree of up thrust and it seems very close if not spot on. Originally I planned to balance on the wing tube but after the install it was sitting in front of it and I just thought I'd fly it and see. Now it's further back - but still on the front edge of the tube.
