It is great fun in getting a exotic design to fly from launch to land and by the way, the pilot needs to massage the throttle, control the nose and rudder and really feel the plane to keep it in the air and land successfully.
This is initial flight inside a 400 ft square area(houses behind trees, can't crash or retrieve) and not trimmed.
When a designer moves from prop to EDF's, it takes an additional set of new rules to get it to design, build and fly. Applied that to the Warthog A-10, and I can very comfortable attack at 6 feet and turn and burn if I want.
Got my Dark Star going the same way even made out of Adams foam.
Learn even more as exploring EDF's. Any exhaust nozzle that is not exiting parallel to flight, will cause a pitch up to your plane, especially the rudderless type.
Go to my youtube site to see other EDF planes flying.
