The only cuts I will have to make in the cowl will be for cooling. Everything else will fit with room to spare. I have Hitec Servos for the plane, 5475's for all surfaces except for the rudder which is a 5975. Thats exactly what Kangke recomends in the ass'y manual and I already have them so.......... The wing is two piece with a HUGE wing tube to connect them. There is a hatch in the top of the cabin area that you remove to attach the wings and each wing is secured with one allen head bolt. the ailerons are about 36" long and two inches wide, the horizontal stab. is 35" wide and the elevators are as large as the stab. I CA'd them in place with the supplied hinges and it appears that I will wind up with about 45 degrees of throw. The only complaint I have is the Vert. stab doesn't fit tight to the fuse. When the covering was shrunk to fit it pulled the center of the stab into a small bow. I think you can see it in the pic. The flying wires will probably hold it but I will add some epoxy just to be safe. I think you can fit almost a 5" wheel in the pants. Those things are huge! One other complaint, the tail wheel supplied with the kit is kinda weak. The assembly is good quality, but the wire used just doesn't appear to bew strong enough for the weight of the plane.
