Paratrike Takeoff. Thrust vector relative to the anchor point

Ensuring that the propeller thrust vector is correctly aligned with the wing's attachment point is crucial for safety during takeoff and flight.

Position the paraglider’s anchor within the specified range (10 cm–30 cm), taking into account the thrust vector, which is parallel to the gearbox shaft. Failure to do so results in a negative rotational force that causes takeoff to occur in the following sequence: first the rear wheels, then the front landing gear. This configuration is critical and very dangerous.

It is important to position two anchor points for both flight configurations: single-seat and two-seat. Position the anchor point further forward, closer to the front wheel, for the two-seat configuration (greater weight), and further back, toward the engine, for the single-seat configuration (less weight). If the passenger’s weight exceeds the usual range (for example, 60 kg/100 kg) on a 15%, move the anchor point back by one inch. The same applies to very light passengers; move the anchor point back if necessary.
