Anyone have more pictures of the water pump outlet block, standalone
and installed on plane? Trying to see the clearance with a side
throttle attached. From the picture online, it looks like 2 tapped
ports on the side. The top one for temp and/or pressure sensor and
the bottom one for the coolant overflow bottle return? You'd almost
need a 90' bend on the bottom tapped port to clear the side I'm
guessing.

I see some people have nice metal welded overflow tanks, anything in
particular to look for regarding aviation?

I attached a little coolant flow diagram I found on the web. Gives
you an idea on flow direction.

Here are a few.

I have some dwgs in IGES or STEP if you have Rhino or Solid Works.

I have come to the conclusion it is possible to move the slide
throttle out far enough to clear a tubing bend. The RX8 p-port idles
much better with the side exhaust ports so no need to keep the slide
throttle so close to the block.

Some Corvettes had nice metal over flow tanks.

Paul,

I sent some pics of the H2O block with slide throttle on my 20b in a
separate email.

Mark S.

I think I have them. They are on the bottom of the front page of the
website. I assumed Matt saw them.

Paul Lamar



Hi Mark, yes I saw the pictures on the website. Thank you. Paul,
when you say to clear the tubing bend, are you talking about the
stock housing ?

Matt Boiteau

The stock is too difficult to use in an aircraft with slide
throttle.

The bottom hole is the main problem.

Burns Stainless has 1.25 OD 2 inch center line radius tubing that
could be tig welded to a flange.

The 2 and 3/8th OD has a 2.5 inch center line radius.

There are some other options depending on what kind of airplane you
are building. If you tell me I can work up a 3D and see what fits.

Tango 2, same as Alex M. I have solid works to see the drawings. I'll start on the plane in a few weeks, just doing the engine planning right now during my down time.

I'm also hoping in a few months, someone might have another PSRU system ready to go. And ignition system ;)
-Matt

If you move the slide throttle out about 4.5 inches from the block you will have
room for a 2.5 inch center line radius 1-3/8" OD  180 degree bend.

I' send you some IGES engine files that will load into SW. Can you receive zips?

Where are you Matt? People are working on gear boxes all over the world :)

Paul Lamar

Sorry for the delay response. Yes I can receive zipped files.

I'll be building the plane onsite in Williston, Florida, just outside Gainesville / Ocala.

Actually this might be a good question for anybody in the area. I'll be living there for a few months with limited tools (I can only pack so much of my shop to travel with me) and will have to build my engine there in Feb. Any newsletter members here live close and could give me a hand / supervise? I'm confident in building engines but I haven't done a rotary before.

Paul, hows the ignition / fueling system going?

-Matt


I am on a push to deliver a couple of the latest generation ign to a racing
buddy in  Fort Lauderdale. A long drive from Williston. I am also taking
one to Germany in January to demonstrate.

As I recall Lyn Hannover winters some where in central Florida. One cannot find a
more knowledgeable  guy on rotaries,

The EFI may not be ready till late spring.

Paul Lamar


Matt,

You can use my tools in the hangar if you need to supplement what you've got, anything on the left hand side while standing at the entrance is mine, the stuff on the right side doesn't belong to me, Denny has a key.
