    The example you gave is a weight-shift trike, not 3-axis control. The pilot shifts his weight by pushing or pulling on the bar (in his hands). Note the joint just below the wing. That is a pivot point. There is no solid connection between the wing and the pod.

    I hope you mean just the seat as an example, and not the whole design.

    Not that there is anything wrong with weight-shift trikes. But some pilots have a hard time transitioning to/from them and 3-axis control since the control action is backward. I, myself, have sometimes wondered about such a structure with a rigid mounted wing and conventional 3-axis controls (like Nickel's Falter 1).

    Trike or weightshift control, I know, I’ve been flying about 700h in such a bird.

    No, it’s just the way the seat was integrated into the structure, as the structure is similar to the AP NG (new generation) :D, without the upper structure of course .

    Herewith we have separated the fuel from the seat, and the fuel tank is at the most sturdy position in this Trike as it would be in the AP NG.

    A similar lower interface between the seat and the lower fuselage spar could be used with the flight controls integrated to it.

    A 60l Tank, but expensive.
    with a B/S you’ll get a 12h range.

    I have a design that targeted specs are:

    Crew: one
    Capacity: one ( 70 kg empty weight class )
    Length: 10 ft 7 in ( 3300 mm )
    Span: 20 ft 4 in ( 6,3 m )
    Weight (empty with fuel ): 156 lbs ( 70 kg )
    Gross weight: 422 lbs (190 kg)
    Wing area: 9 m2
    Fuel capacity: 45 lbs ( 20 kg )
    Powerplant: 2 x 7-10 hp ( 5-7 kw ) jet option
    Propellers: 2 x 27 in

    Performance:

    Maximum speed: 63 mph ( or 100 mph jet option ) 100-160 km/h
    Cruise speed: 62 mph ( 100 km/h )
    Landing speed ( touch down ): 25 mph ( 40 km/h )
    Stall speed: 30 mph ( 48 km/h )
    VNE: 131 mph ( 210 km/h )
    Range: 190 mi (300 km)
    Ceiling: 11 500 ft (3500 m)
    Wing Loading: 4.3 lb/sq ft (21.1 kg/m2)
    Rate of climb: 900 ft/min (4.5 m/s) estimated
    Take off distance: 300 ft (100 m)
    Landing distance: 150 ft (50 m)

    Max pilot size is 6 ft 4 in ( 2 m ).


    It can also be fitted with floats 9+9 lbs (4+4 kg)

    I have tinkered with this design problem about 12 years intesively ( on and off ).

    I assume these numbers would result a real "IKEA aeroplane" that retail price could be 15 000 USD ( without pontoons and batteries).

    I could also sell ( in near future ) a wind turbine to power its batteries at 10 000 usd. Could also charge your Tesla or Leaf etc.

    Something like this would be nice.


    This one says Max 30 min. Neat, but I doubt people would give up Flight Time for Neat.

    I’ve seen the jet powered Mitchel Wing fly, and it produces a massive mental disconnect between the visual and audible senses.

    Electric would cruise around 1 hr 30 minutes on electric..and possibly 20-30 minutes on jet engines. Jet powered could be the first waterborne jet ultra.

    I still like that first Video with good Music. Jets are neat but eat up to much fuel, so short Flight Time. It would be neat to have a Long Ez Jet.

    It had a weak point, just beneath the pilots butt, I believe that it cracked while taxing.
