This is an interesting project.  I will be wanting the magnesium parts,
if available, to develop a light weight engine for LSA application.
Will limit cruise RPM to not go over the speed limit of this class.


George G    what are you planning for a PSRU?  I was hoping to talk to
Geared
Drives at AirVenture but missed him.  How about two 3 or 4 rotors into
the PSRU with one output?
I know a guy that will be wanting the HP you are developing for his
"ultimate" 4 seater, to be started in a few years.

A six rotor engine is not going to work. The e-shaft is not strong
enough for six rotors. It has been tried. It will have severe torsional
oscillation problems.

What if you made the e-shaft from unobtainium?

The the six rotor would then be unobtainable :)
