I am just finishing a Giant Stiner with a G-62 mine came out weighing 21 lbs even. I sheeted the tail surfaces withf 1/64 inch lite ply made it stiff as a brick. I also made the rudder about a 1/3rd bigger. and made the ailerons 1" wider. Should make it fly nice. I put fiberglass parts for the turtle deck, Canopy cover and tank cover as well as the cowling. Use the supergear for the landing gear instead of the aluminum one with the kit. Also mount the servos in the tail Hitec 5645mg one for each elevator and one for the rudder. Had the G-62 sent to CH Ignition and modified for the electronic ignition should make it transition nice thru mid-range.
