How much would a single rotor aviation engine weigh?

Matt

165 pounds  125 HP no PSRU... cast iron end housings.
110 pounds  125 HP no PSRU... aluminum end housings.
PSRU is 30 to 40 pounds.
No cooling system.

Can you put me on your newsletter list?

What do the aluminum end housings cost? How fast would a
single spin for 125hp?

Where does one get or make the reductions?
What did the setup in the picture weigh?

You are on.

Racing Beat aluminum end housings are about $1500 each.

The p-port one rotor engines are rated at 7500 RPM for 125 HP.
The red line in the RX8 street car is 9000 RPM so 7500 RPM is
loafing. We don't run them at that for AC use as the common
Tracy Crook PSRU ratio is only 2.85:1. Belt drives and custom
PSRU's built with the Ford gear set could go to 3.12:1 with
the prop rotating in the wrong direction.

Contact Daryl Drummond for a one rotor e-shaft or complete engines.

Pretty close to 200 pounds as it uses a light
weight die cast bell housing, cast iron end housings  and and old
relatively light weight hollow shaft 30 pound Ross PSRU.
