FES Ex-Uni 6 and Uni 8 systems
A very easily removable propeller driver transforms your scale glider from an e-model to a pure glider and vice versa in seconds.
A slight pressure on the locking pin of the prop adapter is enough, and you can pull off the prop and prop adapter. The model is still a pure glider with the option for self-launch. It just can’t get any better. Also perfect for static displays and exhibitions. Adaptable to various engines and models.
So rubber ropes or starting carts are no longer necessary and the small propeller lays flush on the fuselage.
Internationally, the name “FES” (Front Electric Self-launch / Sustainer) has prevailed for this type of drive. Of course Hacker Motor also offers some drive combinations. Usually large gliders from 4 – 5m wingspan and larger are equipped with these drives.
Large gliders of up to 45 kg (99 lbs.) fly with A60-L glider series motors.
