I am new to be reading this list and I seem to be terribly uneducated and
stupid.  I know that this is true because I am seriously considering putting
a rotary in a Lancair Legacy Fixed Gear. *Not a sign of stupidity, but one of expermentation*

I wish someone would clarify some things for me.

What is the difference in the 4 port and 6 port Renesis, and why should I
choose the one that I should choose?

What does P Port mean and how is it different from the normal port?  *P port stands for peripheral port. The 13-B exhaust port is a peripheral port.

the Renesis (either one) have a P Port *no* and should it be modified to have one
put in it? *You are getting into research to do that*

It seems to me that some of the mods needed to put the rotary in a plane are
pretty well figured out by you guys...Intake, Exhaust, EC2, Etc..  Some
other things, cooling for oil and water, still being invented but with some
idea of what to do.  Other things that seem to be pretty basic and should
have been solved by the certified industry 100 years ago, like how to run
gas from the tank to the engine and back, are still being debated like we
just realized we needed to consider it.

I would really appreciate some help here.  I would like to build a plane and
fly it.  Low on the build and high on the fly part.  *Alternative engines ALWAYS take longer to install than a standard aircraft engine* I am not interested in
doing R&D or starting a business building parts.

There is a lot of discussion about the gentleman who died as to whether he
had his fuel system set up correctly....How can this be?  How many different
CORRECT ways to do it are there?  Is the fuel system for the rotary totally
different from a REAL airplane engine? *The fuel system for a rotary requires high pressure electric pumps for the injectors. Gas (excess to what is burned) is returned to the tank. This results in added plumbing. Some builders try different systems to get around the added plumbing and the need for a 'duplex' valve. All designs have various 'features' and shortcomings.  Apparently small changes from a given system can have unexpected consequences, and this _may_ have been contributing to Paul's problem ( used a 'sump' which has been used on hundreds of Cozy's successfully, but changed the design to be shallow and wide rather than deep.)

I know that this sound really critical, but I don't mean it to be.

Please help!!
