IMO if your gonna go 13x4 go 13X4W depending on altitude it may not be enough. The people who dont like the 13 usually fall on the 14 and vise versa. As far as spoilerons and flaperons start them off at about 30% and see how that makes it fly. All of these mixes are secondary to getting the plane up and flying. you may not need any of them depending on how it likes to tumble.
