With a model paraglider, just like the original, it is possible to change the angle of attack of the paraglider by shortening the A-lines. With the Hacker accelerator set, you have the option to shorten the A-lines via the remote control, thereby accelerating the wing. This allows for fast climbs with the motor, while during gliding or flying with minimal throttle, the acceleration can be reduced to achieve minimal descent.
