Oooooh the Hardly Ableson II .........I like it
In all seriousness......I have to ask why one would pick one of the worst engine designs out there for an aircraft engine???? Power is going to be close to 70 ( probably closer to 60 ) if you expect any kind of durability, they vibe levels are going to be horrific ( yes even the balanced one ) etc etc. The crank design has some severe torsional issues if you add a whole lot of mass to it ( i.e. direct drive ). Like I said.....im curious as to why???
