I owned their 80" 50cc Katana (yellow version) and loved the plane all the way up to the time the wing tube broke...came in at 13#'s 4 ounces...had a Crrc 40cc on the front....plenty of engine. If I had another chance to buy one I would...Fellow club member has the same plane only in the white version with a DL 50cc on the front and it's way toooo much engine for the plane, but it still flys great..We both did the usual on any ARF...pin & tri stock the motor box area, reinvorce the landing gear area and tri stock on the front & back side of the formers in the wing saddle area..We both also didn't use the hardware that came with them....to our standards it wasn't quite up to snuff for a 50cc size plane..
