No problem making the aileron trim tab like the elevator trim tab.  Just very 
small area to work in.  The general wisdom is to make the trim tab about 50% 
larger than the original factory recommendation inasmuch as the factory unit 
was not sufficiently effective.  Moreover, the trim tab in the aileron does 
not have as much leverage as the factory one that trails behind the traling 
edge.  I made mine 1.5 in. by 12 in. 

For a hinge, I recommend that you use the El Primo (my opinion) carbon piano 
hinge made by John Barrett (the "2thman@olympus.net" - John is a dentist with 
interests on the side).  John posts here periodically.  Cut it down in width 
by about 50% and bond in place with Hysol and flox.  It is much lighter than 
the aluminum hinge, has Teflon lining in which the hinge pin rotates, and can 
be bonded with confidence unlike the aluminum hinge.  I believe that John 
gets about $25/foot for the hinge material, and it is worth it.
