I have a lycoming, but I would prefer to build a rotary firewall
forward system. I think I can work the engine specific items, but in
looking for a psru... HELP. Most of the sites I have come across are
dead. Does anyone build a reliable PSRU?

If we can get 5 orders we will build a batch of the Ross copies. No
surprises. 100's have been sold. 10 pounds lighter than Tracy's. I'll
test fly it it on my RV4. Silicon rubber coupling. $3000 each. Billet
housing. Fit Jeff's adapter plate. Same bolt pattern as Tracy used.

I'd be interested in that. Probably next year before I can order
though.
Chad Peterson.
Once we have five commitments it will take a while to complete the
order.

I'll be needing one in 12 - 16 months, Have purchased my kit plane,
it is about to be shipped from US to Aus..
Regards Keith Bennett
Contact Neal he might as well be making more than one. Neil Unger

I would be interested. Could I get a look at the general construction
of it?
Diagram? Pics? Good for 300 hp?
Rod Bingham
Are you in Oz Rod? If so Neal, got any 3D's yet?
Here are a bunch pictures of Tracy's stuff.
It depends on how you get the 300 HP and the RPM you get it at.
If turbo that implies more torque than a normally aspirated
P-port rotary putting out 300 HP at 9500 RPM.
It has been used on a 3 rotor turbo that puts out
more torque than one can get with a 2 rotor engine.

Paul,
Today I had the drawings done for the "flex coupling" so once
that is finalised the initial prototype can be made for testing. I am
calling it an improved RWS PSRU as it will fit exactly where Tracy's PSRU
exists. Now attempting to ascertain the weight to compare. Will definitely
be lighter but how much will be the surprise. Once the prototype has
lasted
the 50 hours I will aim to produce them in batches of 5 for sale. Now to
build an engine mount ready for the test bed based on an RV9.
Neil.
The 3D drawing program will tell you the weight of the parts.
If it is solid works you can export an IGES file and I can load that into
Rhino and determine the weight of the part.
