Hi everyone! Happy belated New Year to all the kitfox family!


Looking to rebuild a kitfox mk2. Has the grey head rotax currently that needs to be over hauled. Just from sitting more then anything.. I do want to put something with more hp because the plane will be used on floats. I heard of the 618UL(74.6hp)
But cant find much info on it. I have read about the 670 rotax on here but I must admit I'm a bit wary of the 670. I have not had any real success with that engine in sleds.. understanding that there is some difference I'm sure when getting into the 670ul(if it is a true ul670..

Any help would greatly appreciated!

This build is all about power to weight and reliability!

Thanks!!!
