I am thinking of machining a batch of one rotor e-shafts.
If your interested I will put you on the list.

Hi Paul,
Can you provide some additional details around the expected
specs of a single rotor engine? Weight, expected hp naturally
aspirated, expected hp turbocharged, likely engine dimensions etc
Thanks!
Matt Humble.
About 150 pounds plus or minus 25 pounds less the gear box.
Of course that is assuming racing beat alloy end housings.
We should be able to get the gear box down to less than
35 pounds with a redesign. Still working on that.
It would be about 130 HP at 7000 RPM with a P-port
It is real easy to add a small turbo because it can be bolted directly
to the rotor housing. Based on what we have learned with the TTC engine
250 to 275 HP would be available.
One should be able to set an altitude and speed record in
the lower weight classes.

Paul,
Hope this message comes out in the right way for you, it's g-mail which
I really don't like.
I could be interested in a single rotor e-shaft or two depending on the
price and I would also be interested in set of aluminum end plates for a
PP single.
In the last few months there have been some amazing acheivements in
aviation . Electric flight across the Atlantic and then around the
world. Truly amazing feats yet almost completely overlooked by the
media. Your work on the TTC is going to be more of the same, a truly
great achievement but primarily it will only be noticed by us rotor
heads, so it is sort of like singing to the choir, so to speak.
To my mind (which seems to be wrong more times than right) for the
rotary to suceed in aircraft it needs numbers. Turbine beating marvels
like the TTC are great but they are only for a few players. Those that
can afford the fuel can easily buy a PT6 or a Walter that is more or
less bolt on, if not indeed just buy a King Air or Citation all ready to
go. There a a lot more of us little fish who need to find a way to get
the burger back down to just a hundred dollars. We're more likey the
ones to get the rotary the exposure it deserves and a single rotor at
100-150 hp is just the ticket.If the there was an affordable source for
the shafts and light end plates then there should be a rise in the
number of rotaries taking to the air. (and it would make me happy)

I agree with all that. A single rotor Mazda is atomic bomb proof.
For one thing it uses the same e-shaft diameter as the 2 rotor 650 HP time
to climb engine also 3 and 4 rotor engines putting out well over a 1000 HP.
You could easily turbo a one rotor and get well over 250 HP.
Not bad for a 99 pound engine.
Those electric airplanes are spectacular but impractical. Zero pay load.
Perfect weather only.

I would be really interested in this eshaft.
I would want to buy one.

The procedure is this you buy the e-shaft and send it to me.
Check E-bay. Or buy an engine and take the shaft out.
When I get ten shafts I will start machining.
Paul Lamar
All good info Paul, it just seemed like you wanted to boost the engine
back up again ☺
There is almost no penalty in it. If your going cross cross country it
is a good way to get there faster and less fuel at high altitude.
In my experience the only practical cross country aircraft is one that
flies 200 MPH. All too often you will have a head wind. In that case with
a 100 HP airplane you could get there faster by driving. I have had my
C182 back and fourth to the east coast and down to the tip of Baja
many times and twice up to Alaska.
