I was flying the SD with a Saito .82 and APC 13/8 prop. I installed a 16oz tank with tail mounted battery and servos. I had the same problems with terrible takeoff tendencies, while practicing proper takeoff techniques. While at a fun fly I was told to try towing in the wheels to help with the takeoff issues. To my surprise the more I towed it in the better takeoffs became. I had about 7 flights on it prior to adding tow in, and I was ready to sell it! After adding tow in I was begining to have a ball with this plane. The following day of the fun fly I miss judged some tree tops and damaged the fuse and wing beyond repair. I will be ordering another!
