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.
