Paul, just curious if I might be able to speak with you regarding
the powersports aviation re215 rotary engine? Respectively, Scott
ingoldsby


Can we do it by email?

Paul Lamar


Sure, I just wanted to know your thoughts on the fwf package? I have
  aquired a new one and just looking for any advice, do and don't s
etc pertaining to this package.  I am very intrigued by what I have
read so far.

Scott ingoldsby

Send us some pictures Scott and I will try to identify the engine.

Paul Lamar

I do know that it is the powersports aviation re 215 rotary engine.
Just not much info on them out there...

Scott ingoldsby

From whom did you buy it from? Did you buy the air plane shown in
the pictures as well? If so the cooling system shown did not ever
work well. It violated K&W rules as outlined in my book "How to Cool
Your Wankel". The book was written partially due to the trouble the
new Power Sport company had trying to cool it.

The 215 refers to the HP. It is lower than what we obtain today due
to two reason. The gear box ratio is lower limiting the RPM to 6200
and the intake tubes are smaller in diameter.

Here is a HP comparison chart.

We have a lot of info on this engine. It is a second Power Sport
company engine. Not built by Everett Hatch and Steve Beckham.

Paul, I bought the whole package.  I wanted to use this engine as I
am quite impressed with it as well as it being a rare find. I will
order a copy of your book and would love to have input to a solution
  to the cooling problem if there is one. I am looking forward to
getting the plane in the air,  however I definitely want it trouble
free if possible

You can get the book from http://www.rotarpower.com/

Move the rad under the engine or on the cool right side.

As in this Glastar 3D.

No I is a vans rv8 also has the James cowl with bottom duct.

Scott ingoldsby


Is this the cowl?

Do you own one of these air planes?

Paul Lamar


That appears to be it, my plane is not quite finished yet. I am new
to the vans and rotary world! I currently own a saratoga

Scott ingoldsby

Do you have the RV8 cowl or the James cowl?

Paul Lamar

It has the James cowl.


Scott ingoldsby

So it probably came from the crashed rotary powered RV8.
The one that ostensibly crashed due to a failed ignition switch.

It had the radiator mounted against the firewall.
That goes against logic and reason.  The air must travel down under
the engine and make a 180 degree and go up through the core between
core and firewall and then forward.

The core  "see's" all the heat radiated from the engine.
Then the hot air must flow down around the inlet duct and out
the bottom of the cowl.

A totally illogical arrangement.

It can be fixed by mounting the rad horizontally under the
engine and using a Kays & London wedge diffuser between
the core and the hot engine. This isolates the hot engine and
exhaust from  the rad. A one degree F increase in cooling
air temp results in a 1% reduction in cooling.

BTW Please Magniflux the pinion gear in the gear box as it has failed
at least once.
