Flaperons
Could one of you gurus explain the purpose and benefits of flaperons?
I've just finished building a GP T-Craft .25, and another member described his takeoff problems with this model (excessively long roll, and slow climb) and I thought of flaperons. Is that a good idea to address it? Am I on the right track?
Thanks,
ChuckR

Small flaperon deflections may help to some extent but he could also experiment with different props. A larger diameter and finer pitch by one inch each may help more than the flap complications. He may be starting with an inappropriate prop size in the first place also. Flaps don't do much for the climb. At that point it's power to weight, or more accuratley, thrust to weight. Back to the prop issue again....
If that doesn't help then TP is right and your buddy just overbuilt that model.

Well, I built mine pretty much to stock. The exceptions were in the tailwheel, and I bought fiberglass cowl & wheelpants. I'm using a Saito 30, which I think is a little stronger than the OS32 he used. I'll weigh it tomorrow.
I'll use Tall Paul's feedback and set up exponential on the ailerons, as well as making it a point to use the low rate settings when flying slow.

Keep in mind that a little flaperon deflection ( less than 10 degrees or so) will help with the lift. A lot of deflection (25+ degrees) will help keep the airplane nice and slow and stuck on the ground.
