no not yet still in the build proses the mods that i have done is to take the stock control surfaces and make then bigger. i took the stock ailerons and doubled the area. i took and cut an inch off the trailing edge and made new ailerons that were 2 inches wide. i also am going to be mounting the engine at a -45 so that it fits in the cowling better. i also added about 1.5 inches to the rudder and doubled the balancer area. i also moved the elevator hinge line in about 1.25 inches and added a balancer. it should be lots of fun once i finish it.
