Electric starter

Two types of electric starters can be fitted to ease starting
procedures especially in flight.

Electric starter fitted on “E” type gearbox. There is also the
possibility to use a rewind start.

Electric starter fitted on magneto side. However for use on
engines utilizing a ROTAX gear reduction unit, this electric
starter system prevents rewind starter application.
