Dan's Mig uses a small OS pulse jet. Smaller than a dynajet. The plane is made from a "kit" that was more a hint than a collection of usable pieces. All major pieces are aluminium. Dan made the wings and stabilizer, designed and executed the control system, devised a way to mount the engine. The fuse may have been usable, I'll check. He devised the controller for the elevator from socket head bolts that key into a ball wrench ends. This allows for the dihedral in the elevator. The engines are very touchy, hyper mixture sensitive and fuel sensitive. More work will be done plumbing the tank. Longest powered flight was 5 laps under power. Fun scale requires a minimum of 10 powered laps, so the plane did not compete. Bob Wilke (not sure of the spelling) helped in sorting the jet engine. More work will be done. The flight of the Mig is an event. A long roll out on the ground as it gets up to speed and fast laps estimated at about 80 mile an hour. The sound of the engine is an attention getter.
