This is a ornithopter, which I made for testing and understanding various basic principles related to ornithopter.

Control:
Throttle: flap wings

VTOL: Control the thrust of the wings at high or low speeds (pulling the VTOL to the bottom at low or stationary speeds can generate thrust, while pulling it to the middle at high speeds can increase thrust, but generally should not be higher than the middle unless you plan to invert during hovering)

Trim: Control the pitch angle during hovering

LandingGear: Switch between hover mode and flight mode

Roll and pitch: Control the tilt angle of front, back, left, right during hovering, and their functions during flight are the same as those of a regular aircraft

Yaw: Control the heading during hover mode.

Activate1:Fold wings

Activate2:More stable hover mode

Operation method: Click on LandingGear to switch to hover mode, then pull the VTOL to the bottom, and then increase the throttle. When it reaches sufficient altitude, click LandingGear again to switch to airplane mode. Then you can pull the VTOL to the middle position to increase thrust and speed.
