Hi Kevin,
Sorry to alarm you with my crazy behavior, but our Europa is legally a motor glider, and as such, we do on occasion shut the engine down (and feather the prop). The first time was in gliding range of the old Castle Air Force base with a 12,000 foot runway.
Even with the short wings installed, I feel it quite appropriate to explore the power off/on and reserve tank behavior, under controlled conditions, or course. It is, after all, an experimental aircraft, which makes us all test pilots, I believe.
Regards,
Terry

Hi Bob,
One of the reasons Dave and I built the Europa was the promise of a motor glider option, later on. Even before buying the long wing kit, we felt it appropriate to test some important issues. For example, if you run the battery dead while motor gliding with the engine off, can you do an 'air' start with a geared engine, and could you get it to stop wind milling during power off souring. Both questions were answered in a very controlled experiment at altitude over a 12,000 foot runway. We were quite satisfied with the results. It will stop wind milling (at about 55 kts) for souring, and can be air restarted by pushing the nose down a little to get a speed greater than normal for souring (about 110 kts).
The glider pilots out there are probably not quite as nervous about flying REALLY quiet airplanes.
Regards,
Terry

yep as with any vehicle you have to find your range, especially if you intend to tour and in less inhabited areas. 68ltrs is not a huge tank at 17ltrs per hour. Even in Scotland its quite hard to find fuel. I thought I had fuel for 3:45, but I was down to 11 ltrs after 3:10. I thought I would average 115kts but with a stop and taxi etc it was 102kts.
I am also cautious though and had 20ltrs in a can in case I had to 'put down' somewhere.
On the prop stopping, I am sure that on one of the promo videos they stop and start the engine - as if we should all be doing it!
very interesting that it can be started at 100kts.

The same Rotax engine is used in quite a few motor gliders, and these
folks stop and start the engine in flight as normal practice.
