That is true compared to a four stroke piston engine, but the Wankel is
still more efficient than a 2 stroke piston engine. Not that it matters
in our gliders, as each is equipped with an appropriately sized fuel
tank, and fuel cost isn't going to be an issue!

Also I should have mentioned:

There are two Antares 20E and one Arcus E for rent
in Namibia. No problems with temperature !
You often see these gliders on the front page of OLC.

PS: Someone needs to come up with a really good
and appropriately foul acronym for "motor out and
not running".

Guys

Many thanks for your thoughtful comments and insight. I had read most
of the literature of every type of self-launcher and touring
motorglider, but your first hand experience is what i needed to hear
about. Clearly there are substantial tradeoffs and advantages and
disadvantages for every type of motorglider (not even considering
cost!). I will keep monitoring manufacturing developments, especially
for less expensive electrics. Unfortunately i am too tall (6'4") for
the Silent electric (assuming the cockpit is the same size as the
Silent petrol).
