Pilgrim,

My ailerons also end short of the wingtip...even with the second to last rib. One note is to make sure you seal the hinge lines, because mine had some flutter when i first flew it (ailerons were sealed, but rudder and elevator were not)...i've since changed props and sealed the other surfaces and it is no longer a problem. I only have one servo on the ailerons, but it is beefer than a standard servo.

Thanks for you compliment on the covering...the wing is monokote, the fuse is actually glassed and painted (as an experiment)...liked how it came out and learned a lot in the process...

I have a few more build pictures, and can always take more of the finished plane if you have any questions...i love this plane :-)
