Had a conversation with a fella in Tassie this afternoon.
He has a LYC O-320B2C engine for sale, professionally overhauled and then pickled in Adelaide in 2004, it's still in the box.
Was out of an R44 helicopter, but I see with some research some do use this B2C in aeroplanes.
It has the conical engine mount, not the common dynafocal. It does have the oil sump for horizontal installation in aeroplanes.
LYC manual shows B2C takes a fixed pitch prop. (seems it was destined for R22 though, or perhaps just not used in any other type certified aircraft)
Would ideally suit an experimental aircraft. He was going to put it in a Baby Belle, that project did not proceed.
The price seems real good to me. I'd buy it myself but my project is already set up for dynafocal mount and I have an engine.
I have his phone number and email, but I won't post those here. PM me for that.
First to ask "how much?" here will face the firing squad. I'm just trying to help the fella a little, you can talk turkey with him.
