I like to use the booster tabs on some of my planes, especially the aerobatic, 3D if you will. Why not make use of them.for models. Also playing with flying stabs. The smaller foamy are good to experiment with but I do have booster tabs on the ailerons and rudder on a 1/4 scale Corby Starlett. The wing shown below. This Zoombi has a booster tab on the oversized rudder where, before I had a hard time getting around the bottom of a knifedge loop. Now it's no problem at all. Flying stab shown is on a Flash 3D. Will do snaprolls in its own length. I just slow down first The Corsair had booster tabs on the right side elevator and aileron. One reason it was fairly agile for its size.
