SNAW TW-108 "T-Bird"





* USER MANUAL *

TRIM = Trim tailplanes
VTOL UP = Wing rotation and aerodynamic braking

AG7 = Navigation lights
AG8 = Locking of all devices in normal flight position (Wing rotation, gyroscope and aerodynamic brakes)

B = Wheel 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 centered, 100% engines. Rotation above 140 MPH. 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 not recommended. The operations are complex and are not reported in the manual

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 *

Fictional story:

Born to be the charter between small islands using a modify fuselage of a helicopter to be cheap as much as possible, use 4 small engines of about 700 CV each.

    @LiamW as i wrote in user manual, the gyro must be disabled for normal flight 😊

    The gyro gives it trippy flight characteristics though... wish the gyro had PID loops so I could calibrate it like a quadcopter

    Or is it just like that because you were too lazy to make a subsonic airfoil? JK, I almost always use stock wing appearance and sometimes exactly what you’ve done here. This thing is great @Baldovino

    I see you are using a biconvex airfoil for minimal drag at supersonic speed
