Ahh h Robert I see what yo mean about the aileron lining up. I dont know the answer but Mike seems to have covered it.

Mikes pic of the aileron brilliantly shows the geo problem, and no offence Mike but a ball link on the horn is not good practice in my opinion. That said, chance of twist on those horns is probably much reduced - they are alu arent they or gfn? and they look like pukka ball links too.

off to bed now... long day and no flying !
