Hi Paul,

This Tony guy is one of the owner of the e-Go plane.  This is a brief
description of what they have achieved so far

His intention with the Rotron engine is to push forward the engine and
use a prop extension or shaft.  I told him that this has been considered
before but tortionnal vibration was an issue.  He thinks a rotary engine
has almost no vibration so the extension should not be a prob.

In any case, I invited the guy to the newsletter.

I has no vertical or horizontal vibration but a one rotor like the
RoTron AKA AIXRO has very powerful torsional vibration.

That may have been the cause of the shaft drive Rotamax powered Vampire crash.
