The wheels gotta go. Heavy and junky. The tail wheel dosn't fit the hub. The guide wires vibrate loose. An easy fix is to not use a clevise on both ends, put a Z bend on one end and it can't turn. Also the small nuts and bolts that attach them to the tail feathers must be replaced with bolts with nylock nuts. Or go cable or carbon. Control horns are light but do the job. Say good by to the wheel pants. The light ply mounting block is too small, it should cover as much of the in side as possible to be strong. I replaced them with custom pants. The cowl cracks all over but some how stays together. You have to oversize the holes for the mounting screws and isolate them with servo gromets (fuel eats them) or make them up with pieces of fuel tube. The CG in the manual is not correct. It is 4" to 3/4" For the motor mount placement the horisontal line from the bottom up is 3" not 3 1/2" The control horn placement on the rudder is 7/8" up from the bottom not 1 7/8" A couple of areas of sheeting on the fuse came loose after time but no big deal. Good luck, Joe
