Flaperons
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.
