Despite the reported lack of vibration the bolts holding
some Wankel engines together seem to have a habit of falling out?
Assuming all motor-gliders are unreliable seems a safe bet.

The 26E was not affected, so I am not an expert on it; however, my understanding
is it's a bolt problem, not vibration related. Seriously, it has so little
vibration, I can't imagine that it could break a bolt. Vibration is simply not an
issue in our Wankel powered gliders.

It is a bad bet to assume all motor-gliders are unreliable, when so many are quite
good. I have had fewer lost soaring days because I couldn't self-launch than when
I had to use tows, and I'm very glad to be a FORMER owner of towplane!

It is not a good bet to assume the engine will start when it is your only chance
of avoiding a crash. It's not just the engine that may malfunction, but the pilot
might make a mistake.
