I've been flying my Shoestring since August and its been a blast. It was the first plane i made the maiden flight on( I've been flying since Oct 2000) and it took off like a dream. I fly ot with the OS61 and at half throttle it's fast enough for me. It lands better then the Four Star 60 I had. Someday I may have build one 1/3 scale. Right now I'm Building the Dare Shoestring, its electric with a speed 400 hundred, hope it flies as well.
