Starting and stopping the engines
The engines in these aircraft are rather basic (but very light and
powerful). They have very few controls and using them is a matter of
just pressing a few buttons. Both engines are extremely noisy and
cause an alarming amount of vibration. If you are not used to it you
are sure the engine is eating its own head gasket before starting on
ripping the cylinder head to bits. Don’t be alarmed. And don’t try to
use the radio with the engine on.

To start the engine:
1. Keep speed below 100 km/h
2. Retract switch to EXTEND (AUSF)
3. Engine ignition ON (Zünd EIN)
4. Set Static source for engine operation ( MOTOR)
5. Wait until green light is shown
6. Fuel Switch valve to OPEN
7. Increase speed to 120 km/h
8. Pull Decompression lever
Engine should now start. Keep the speed at the blue line to get best
climb rate. There are no throttle controls, i.e. the engine always runs at
maximum power.
