Hi I am building the 1/4 scale Merlin from a set of castings I purchased from a guy that did not have the equipment to make it.
I need some help withe the gears in the gear case as some of the plans are missing.
I am a new member and have been making engines for several years my last engine was a 1/3 scale LeRhone rotary. I am looking forward to seeing other builder work.
