Hi!
You could shorten the ailerons slightly 100mm at the tips ...but this is not necessary if you just are certain to make the aileron linkage sloop free.
What I react too though is your plan to use a 10x6 prop on that pattern airplane...it will not work too well, as it will produce a lot of noice and no peformance.
Better use a 12x6 or 11x8 APC or RAM prop. A 11x8 or 11x7.1/2 prop was size to use back in the "old days".
