Dave, you are correct. I got to thinking about that last night and decided I missed the mark with my answer. I always use a single servo per aileron. The single per wing did't pop to mind.
On the speed and such with two per surface. Most guys that go that route want the speed, so they use the fast servos and high voltage to get more power and speed. I just thought this was to big a step from no ailerons. Again, I didn't understand the question correctly and as a result gave a bogus answer.

Unless there is a new release of the CG Super Chipmunk that is a lot larger than the 90 four stroke size one that CG kitted, a single aileron servo is all you need. In fact I have an older pattern plane, almost 90" span with a 120 four stroke engine and it flies just fine with a single "standard" size (50 in oz) servo on each aileron.
The issues of balancing the mechanical linkage and the servos through a match box or the likes is not something to get into for your first aileron plane. In fact, if the Chippie is your first aileron plane, I would get it finished and set it aside for a while and fly a Stick or 4* or like plane for a bit first. Gliders and powered planes are two completely different animals. Iam having issues controlling my glider as it responds so slow.Of course, I have problems controling my powered planes as the respond to quickly also. A powered plane will respond much faster to the sticks.So anover powered dual servo, super fast aileron setup is not a good jump for you yet. That is for the big, 33% planes and above and for the aerobatic crowd.

In part of your statement above ("balancing the mechanical linkage and the servos through a match box"), Imay bewrong butI think you may be referring to having more that one servo per aileron, vs. one servo for eachside (L-R) that I think he is asking about in the original post, but Imay be off on that one, Iwas origianally thinking thats what he was asking about too.That being said- Ithink one servo per aileron simplifies setup and minimizes the chance forlinkage slop as opposed to a bellcrank setup, and reduces the possible flexing you can getin a strip-aileron configuration.
One correction though, the comment on"... anover powered dual servo, super fast aileron setup....". Just to point out, dual servo vs. single servo does not change the "speed" at which the aileron moves, the voltage does that. The servo, whether using one or two, still moves at the same speed, but you have more torque available per aileron. Same thing with using two servos on each aileron per side, no change in speed, only the torque to move (and hold) the aileron in place is what is being increased. Just my $0.02.
