again, guys,
you are all forgetting several things.
1. these are CA hinges, and will bend wherever they are exposed. so if you put 1/8th inch gap in you aileron, they will bend wherever it's the easiest (ie centerline) and there will be no binding

2. while the surfaces may not center perfectly, it is a trainer, which fights being turned, and will resist small mis-alignments. being trainers, they are also built to allow the modeller (presumably a first timer) to make mistakes during the build, and not have them show up in the flight characteristics or interfere with the training ability of the aircraft. trainers are extremely tolorant of elevator mis-alignments, (very common) improper thrust line (again common) and even a crooked wing, caused by a novice getting used to the sensitivity or rc planes and pulling too many g's in the process.

3. the ailerons are too small to really worry about flutter, especially if you seal the gap.

basically, if you want to do it right, shim up the TE of the wing and put the hinge line center with the torque rod. however, it is a trainer and you could get by without it. i would personaly do it the right way, but either will work just fine.
