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

Move the rad under the engine or on the cool right side.
As in this Glastar 3D.
Paul Lamar
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.
Paul Lamar
Paul, the engine has been factory rebuilt to zero time, it could be
the one that was in the crash. Was the ignition problem corrected.
do you happen to know the serial number of the engine that was
involved in the crash?
Scott ingoldsby
That is strange. The Mazda factory never sold
P-port engines like that. I find that hard to believe.
I was lead to believe it was an off the shelf after market ignition
switch.
When the switch failed the engine stopped because there was no
12 volts going to the engine.
No I do not have the serial number.
Paul Lamar
I believe it was rebuilt by powersports themselves. I read a bit
about the ignition failure,
is this something that I should be concerned about now?
Scott ingoldsby
Spend a little more and put a aero space quality ignition switch in
there.
That is a single point of failure.
