I would like to hear some thoughts about using spades on the ailerons, instead of boost tabs. It is very common on full scalers like Decathlons. The spade looks like, well a spade, is hung horizontally under the aileron, forward of the hinge line, and rigidly mounted to it. Seems rather straightforward to me, plus there are no moving parts. It has the side benefit of giving the modeler a chance to counterbalance the aileron to help avoid flutter.

Anyway, I have been thinking about adding them to my next project, but have never seen them on a model. Hanger rash is my main concern.
