AN EDF STOL---- result of an vtol failure

Failure Equals Success
Seven years ago this project was a result of using an EDF with a VTOL concept which failed and an offshoot that gave me a new STOL project that is really different and also a first. I also submitted this project to FT and I hope it get published where I explain more in detail.

Anyway, look at the beginning of the video and you see the EDF rotate(using the rudder) up 40 degrees max and goes below the fuse 60 degrees max. So now we have a vertical(+ or -) lift and forward component which determines forward speed as the nossle changes angle with respect to the fuse. On takeoff, fuse is fixed while on ground, while on approach for landing, the EDF vectors change when the nose angle are either above or below the fuse that change the drop rate and forward speed. Got the idea? On the second takeoff(maiden flight) you see the result of nozzle angle that is alot lower then the first causing a longer . In a couple of cases with gusty winds, the nozzle was max down to move forward speed.

Nozzle Control equates:
No rudder, the EDF nozzle is zero degrees, rudder right is nozzle up, left rudder left is down.

Flight in video is erratic due to now a NEW STYLE of flying. Regular horizontal flying is no rudder and is the same. Takeoff and landing approaches is like a differential equation:
Result of plane's forward speed and lift/drop EQUALS the angle of fuse(elevator up or down) plus nozzle(up or down) + thrust of EDF(some throttle to max) + add the wind(zero to gusty) and guess what!!! YOU NOW HAVE A DIFFERENT WAY TO FLY A PLANE.

Result:
It now takes off in a short distance(with no landing gear, even) and length of landing is how steep/shallow you fiddle with the nozz/fuse angle, etc,etc.. Definitely a STOL type of plane.


Any questions?
