This VTOL aircraft totally out of my original imagination was supposed to be a simple chore by modifying my previous one [SNAW TW-108] (https://www.simpleplanes.com/a/rtkF5q/SNAW-TW-108-T-Bird-Tilt -Wings-VTOL) to insert visible mobile surfaces (the original has no control surfaces on wings and tail) but turned out to be a project that required a virtually complete reconstruction. I managed to save only the body and the engine gondola.

The three-dimensional mobile wing can not be changed in any way without permanently welding it in a horizontal position, so I had to delete everything and start again from a bare fuselage. On the other, as in other previous projects with three-dimensional mobile wings, such as my [SNAW FA-88] (https://www.simpleplanes.com/a/rg64Xj/SNAW-FA-88-Variable-Geometry) i two sides must be made by hand, without using the mirror function which in turn blocks any moving part.

It was therefore not a work of a few minutes, but of a few hours that unfortunately I had available due to an influence that blocked me from doing anything else.

• USER MANUAL *

TRIM = Trim
VTOL UP = Wing rotation and aerodynamic braking (with AG8 enabled)

VTOL DOWN = Flaps (They looks great, and they actually works, but the flap's aerodynamic effect is a trick. The "flaps" effect is obtained from mobile surfaces hidden inside the fuselage and not from the parts in the wings)
AG7 = Navigation lights
AG8 = Locking of all devices in normal flight position (Wing rotation, gyroscope and aerodynamic brakes)
B = Wheel and aerodynamic braking, and engine shut-off
Gear = Landing gear up / down together with landing lights

• TAKE OFF *

VERTICAL - AG8 enabled. VTOL all up, 40/50% engines. Once in the air retract the gear, then VTOL centered and wait for the wings to complete the reconfiguration (the movement is deliberately slow). Once in normal flight configuration, disable AG8. No manual operation necessary on the controls, the plane will do everything by itself.

SHORT - AG8 enabled. VTOL halfway up, 100% engines. Once in the air retract the gear, then VTOL centered and wait for the wings to complete the reconfiguration (the movement is deliberately slow). Once in normal flight configuration, disable AG8. No manual operation necessary on the controls, the plane will do everything by itself.

CONVENTIONAL - AG8 disabled, VTOL down for flaps, 100% engines. Rotation above 140 MPH. Retract gear and then flaps. Pilot the aircraft in a conventional way.

The aircraft needs some adjustment using the TRIM in quantity inversely proportional to the speed.

• LANDING *

VERTICAL - AG8 enabled. Approach the landing spot at very low height and speed (the plane during the conversion automatically rises and the faster it is, the more it rises). VTOL all up. Use THRUST to go down more or less quickly and to cushion the contact with the ground. As soon as the gear touches the ground, use B to brake and switch off the engines, avoiding rebounds.

To correct the position in the air: nose down to create forward thrust, nose up to create it backwards. Roll to create lateral thrusts (you will have to compensate with the rudder a certain rotation on the vertical axis due to the ailerons)

SHORT - Possible but hard and not recommended. The operations are complex and are not reported in the manual. A normal landing process is short enought for most situation, where there is not physical space, a vertical one is way better.

CONVENTIONAL - Approach at low speed. Land in a conventional way. Possible with both AG8 enabled and disabled, but it is recommended to disable it.

• COMPATIBLE WITH THE AUTOPILOT *
• CAN TAKEOFF AND LAND IN WATER - But need AG8 enabled *
