I decided to start building....

Ive wanted to build a stol airplane for quite a while, Ive got a genral idea what I want, and enough parts to (slowly) start building and Im going for it
The original plan was to copy the channel wing beacuse of its simplicity and awesomness (it made enough lift standing still (no wind) to take off with no ground roll (it needed some speed to fly for the rudder and elevator to work)
this picture was taken in 1953 at 10 mph airspeed

but to make it stable it needs to be a twin prop layout (twin engine or a mess of chains)
those channels are going to be a nightmare to make strong and light
if the engine fails you have the glide ratio of a ford van
so ive settled on a single engine prop in front blown flap narrow wing span, the blower will also suck the boundary layer off the wing near the middle
interesting video 22 min is the idea im copying

it works

Im copying the wing chord, rudder, and elevators off a zenith c701
so the plan is to have the 500 spin the supercharger making a lot of air at 10 psi (40 horsepower worth to be exact)
burn most of that air (if nessesary all of it and water injection to keep temps reasonable)
blast it out the trailing edge at a 45 downward angle (10 psi in an open ended pipe is gonna have some power)
the polaris will be out front making quite a bit of airspeed and hopefully it will lift off without moving
the plan is to be able to fly it while tied to the ground and not going anywhere till i get the feel of how it behaves
im hoping it will weigh under 700lbs, 130hp to the prop, 40 worth of compressed air, not sure how much power burning 30 gallons an hour in the burner is going to add, but im sure it will be plenty
this is going to be a long term project, any parts, input or whatever apreciated
