I just purchased one of the 140 hp 4 cylinder engines from Hibshman... I need to get in line to get your kit for a redrive. This application will be a tractor configuration.
Hasn't Ernie got a four cylinder Yamaha running with a gearbox? I think he fly's it every other day for rotor test flying.
We have a three cylinder Yamaha engine here ( NZ ) that's been waiting a while for a gearbox. At last we have the time ( if not the money ) to finish this project. This is a gear drive bolted directly to the engine, not some sort of adaption.
Like our EA and EJ series gearboxes they look as part of the engine. These will not be " project managed " to be sold before we are happy with long term tests.
Pardon my knowledge or lack there of, but what is a YG3 and YG4?When I google them, I don't get images of this particular engine. Thanks in advance.
Perhaps I jumped to the worst conclusions after becoming frustrated running Google & Yahoo searches then quit trying. All apologies, have edited the recent post, much thanks to you for taking valuable time to research and find these. Still trying to become a better citizen.Post #76 updated from original post by me. Yamaha build threads have not disappeared. Were not found using the forum "Search" feature, but they turned up in a simple (Non-Google) internet search.
