I just finished my version of the Giles 202 : Magnum .61 2-stroke, side mounted, Slimline pitts muffler, GP adjustable mount, 5 cell 6 volt pack next to tank in nose (on left side to balance engine), servos in tail to get CG right. Hitec 475 servos. No extra weight needed for balancing. All up weight on digital fish scale : 6 lbs 9 oz. Here are some pics. May maiden her today depending on the weather.
