I have added a power to weight ratio rows on the bottom
    of the Boeing VTOL table.

    Looks like we need to get the empty weight down to 666 pounds.
    13B p-port engine with aluminum end housings is 165 pounds.
    Gear box and rotors are 100 pounds.
    Drive shaft and accessories are 100 pounds.
    That leaves only 300 pounds for carbon fiber structure.
    We will probably need smaller wings with less wing area if not a delta
    configuration. A delta configuration would ease the
    CG, structural problems and high speed aerodynamic drag.
    It would also shorten the drive shaft from engine to gear box.
    A small canard for enhanced control purposes might be OK.

    No room for anything other than an optimized design in carbon fiber.

    Sorry Perry.

    The gross weight needs to be less than 1200 pounds.
    Payload and fuel must then be 534 pounds.
    Two 175 pound people are 350 pounds.
    That leaves 184 pounds of fuel or 31 gallons.
    At 10 gallons an hour 200 MPH cruise that gives us 3.1 hours
    or 600 mile range. Beats a Robinson R22.

I haven't worked out the details yet. I started with a standard Long-EZ
model that has gross weight of something just less than 1500 lbs. and
the current simulation is running around 1200 lbs. gross I think. With
300HP and 12' rotors it is underpowered. I currently have it set to
400HP and it will definitely climb vertically with that power.

I brought my son's joystick to work so today I'm going to play with
rhino rudder and elevator surfaces to see if I can control hover.

Here is the delta configuration. Motor cycle passenger
configuration.

Only 10 foot span. Will fit in a one car garage.

50 square feet of wing area. Wing loading 24 pounds per square
foot. Way less than most tilt rotor VTOL aircraft which average
100 pounds per square foot.

Tilt rotor VTOL aircraft do  not need a lot of wing area because
at 200 mph the dynamic pressure is 100 pounds per square foot so
that is 5000 pounds of lift at a C sub L
of one. 1200 pounds gross will give us a C sub L of only
.24 no problem.

At 300 MPH the dynamic pressure is 234 pounds
per square foot 11,700 pounds of lift at C sub L of one.
The required C sub L would then be only .1.

No problem getting the structural weight under 300 pounds
in a two piece blended wing body female mold. This will be real
easy and quick to build as well.
