Luke. A small point but the canopy position Q you raised??

I looked at my mk1 and mk 2 I prefer the canopy further forward. Cant say I noticed a jot of differance on knife edge though.

Sprink. Apart from a cock up on rib 8 which had the 1\4" slot at the rear .67mm off line for the first 50 kits!!

I have built several (as you can imagine) and never faced the problem you have just described???

I had one guy tell me the tongues on the former sides did'nt fit the holes in the fuzz. Never had that problem either??????? I think he must have been trying to make space for his epoxy

Phil. I know what you mean about the tabs!! I ummed N arred about it?? Problem is grain direction IMHO. It causes more problems than it saves. If I remember you had NO aileron trim from your first flight?? So where did you have the problem?
