Hi,

I've made a 4-star 120 wing and fully sheeted it.

The trailing edge is now 15mm thick. The (kit) aileron is 9mm thick.

I'm considering making up my own ailerons, but before I do, I just want to get some impressions about another option: Sanding the TE (top and bottom) at a taper to bring it down to a 9 mm thickness.

If I did this, will there be any negative effects? Flutter? Reduced stall speed?

Thanks,

BK
