Hi folks! This will be my 1st post on any kind of forum so i hope i do this right. Im pretty new to the home built aircraft scene. My question is, I have a rotax 618 ul that i plan on using for my 1st build. I plan to build the air bike tandem. What reduction drive do i need and where do i get said reduction? Next question would this engine be good enough? Its around 75 hp engine. I also need to know what a good size prop for the 618 is. The air bike tandem calls for a 64x36 prop but thats for a 50 to 60 hp engine. Could i use a groung variable pitch prop to tune it in for a 75 hp engine? Thanks in advance
