Hi Chad
Do you think you could have someone find an explanation for the second aileron on this model? I don't know.
Friend of mine told me that throw of aileron on tip is larger. So there are 4 servo on ailerons.
Plane is made all in wood. Weight is 4650 g. New Plettenberg (diameter is larger).

Maybe for Snap, Mayr use to fly slowly, so maybe it help the plane to snap with slow speed.
1- It's the typical solution for several big planes (airliners or so): the smallers outside ailerons gives you an excelent roll performance with smaller deflections without increasing drag too much. A combination with the inner ones gives you excellent performance at low speeds...
2- Also there is the flap thing. You can use the entire aileron as a flap too but you risk some tip stall or loose of roll presition (due to close stall condition on wing tips) specially with this type of wing planform.
This is the basic; now it's necesary to ask the plane's owner how he uses that surfaces... may be he focuses only on point 1; may be a combination with point 2 too.
Hope it helps.
