Paul,
Can you run aviation fuel in a rotary?
Ed Moreno
LEZ 97%
100LL (lots of Lead) is no problem. Just cuts the spark plug life
to about 50 hours from 100 hours burning auto gas. First sign is
a noticeable drop in power.
Ed, are you related to Fred Moreno the thermodynamics's or
the cooling guy?

Paul,
The reason I ask is I'm a little concerned about using auto fuel in my Long
EZ because RAF warns about it possibly damaging the fiberglass. However,
the RAF statement was written a long time ago. Some recent info I've read on
the subject said there was little or no effect. The tanks were only sealed
using the old safety epoxy. Has there been any research on this?
Also, are you saying the spark plugs should be changed every 50 hours if I
use 100LL? If I use auto fuel, how often should I change the plugs?
You can see my project at;

would be appreciated.
I have an Uncle Fred Moreno in the air conditioning business located in
Sulphur, LA. Do you know him? If so, small world huh?
Ed
Most of the composite guys we hear from are using auto fuel
in their rotary powered airplane with no problems.
I would change the plugs every 100 hours using auto fuel.
Every 50 hours using 100LL.
I think Fred lives in California.
Your airplane is looking good.
IMHO I would forget the two A/C cores and use one modern 2 inch
thick rad about 18 by 19 under the engine. Will make
the plumbing simpler and more reliable. Don't forget to
use blue silicone hose and constant torque hose clamps.

Is that a dynamic chamber intake plenum? If so I think
you would get more power with a simple plenum. The intake
runners look about the right dia. and length for your 2.85:1
psru. Is it street ported?
Be careful with that Andair valve. Some models can
be moved with very little force. The engine will quit
if its half way between left and right.
