You might want to be careful with the stab position as the elevator mono block stab is not symmetrical!! Both the leading edges and the tailing edges are out from each side. Leading edge by about 4-5mm and the trailing edge by about 3mm from the other side! So expect to be trimming the ailerons depending on your airspeed. As well as the large gap between the gel coat/ fiberglass and the mounting former for the elevator axle blocks. Just a note of caution to all the non builders out there that just assemble and fly.
