Some interesting pulsejets
And an odd control line speed ship, with a Dynajet on top. Definitely been flown. Odd because it has landing gear and a built-up wing. Most Dynajet models I have ever seen are either scale jobs, or dedicated speed ships, with solid wood or metal wings, and drop-off takeoff dollies. This ship would be an easy conversion to R/C. Just add ailerons and two or three servos. Doubt if rudder or nosegear steering would be needed, you would probably be airborne in ten feet. Check out the welded metal tank/cockpit. Doubt if I will actually DO the conversion, as there are no deserts convenient to here where I could fly the sucker without getting arrested on a noise complaint!
