Bill, not quite certain how it do that. I can understand that the
rotor being coated would tend to lessen the amount of heat the rotor would
absorb and therefore keep the temp of the oil ,which cools the rotor,
down. But, it then seems that heat has to go/do something. I agree
there should be some increase in overall efficiency by keeping the temperature
of the combustion chamber elevated. However, I believe that heat has to go
somewhere and I think you would see a rise in coolant temps.
Interesting
thought. Two things have happened with the recent engine, one of
which I've only mentioned to Tracy. First, the low oil temp, but
that's only partially due to the ceramic coating. The other is a rise in
EGT's. I've had a problem keeping EGT's below 1750 in climb since
the rebuild. It never dawned on me that some of this might be due to heat
that didn't go into the oil. Hmmmmm
As for the
balancing, I already chimed in on that over the backwards plastic plane
site. I've heard tale that the Renesis rotors aren't nearly as consistent
as the 13B rotors were in weight. I know that Bruce was not really
suggesting balancing in the past, but maybe the Renesis can make
better use of a balancing job. Mind you this is pure
speculation. For $350, and no inconvenience, there's no doubt
I'd get any engine balanced.
Cheers,
Rusty
