Paul,
I have only recently joined your newsletter so bear with me if I am
revisiting subjects that have already been discussed.
I am in the process of designing and building an experimental amateur built
airplane and am intrigued with the possibility of using a rotary engine.
My initial observations at this time are that the Renesis engine holds
significant promise as an aircraft engine but in order to achieve that
success the engine must weigh approximately 80 lbs. less than currently
configured. In order to achieve that weight reduction it is necessary to do
away with three large pieces of cast iron. Mazda has found a way to replace
those pieces of cast iron with aluminum alloy in their 16B engine. It can be
done. With all the brain power available on this site, we should be able to
solve this problem. Perhaps the answer is in hypereutectic aluminum alloy. I
do think that none of us is as smart as all of us.


The Eltings

You have a lot more to deal with than just the engine.
There is the cooling system the gear box and the prop.
The big question is how much HP do you need?

Or.................

What airplane are you building?
