Paul,

Does it really run at 4300rpm?


Yes (no offense, but in what hole have you been hiding all those years?
;-))

It is geared down. It is a very, very quiet engine, much quieter than
any Lycosaurus or TCM. Thanks to water cooling which also ends the
shock cooling debate. Welcome to 1990s technology.


Actually,there's nothing on it that wasn't on some airplane engine by the
end of the first world war.
They're good engines, but I wouldn;t have one.
