T-PROP & FES
Front Electric Selflaunch/Sustainer
The wish from scale pilots, to start independent from a winch or other models, is omnipresent. Retractable propellers and turbines are used since a long time ? but these solutions are in addition to expensive buying prices, the heavy weight and the different centres of gravity (retracted and extended) also complex to integrate. Settings and maintenance are not to ignore.
The FES (Front Electric Selflaunch/Sustainer) drive was first use for man carrying aircraft. LZ-design was able 2011 to win the first place as part of the `Berblinger Flugwettbewerb` (international flight competition). Of course model-makers, who flew some time with retractable propellers and turbines, discovered the advantages of this drive.
To meet the increasing and different demands, TORCMAN developed three different versions of FES drives.
