This aims at creating the first Ultralight engine for LSA/ultralight use
Will keep builders informed about the evolutions ( modifications : flywheel removal?... , hub adaptation ,engine mount)
running 18hp (22 on takeoff) continuous for 58kg (estimated mounted engine) can fit many applications (including my project )

it should fit into an Enfield frame if you strip down the front tube. As you can see in the Video.Those enfields are running the 836cc version of that engine which was a desaster.The 812er seems to be more relieable.
