hks is very good engine but just the part is
not easy to have ....japon is not rapidly

but with a good engine, you don't need a part

Some have used the GEO conversions with a raven redrive

Im waiting to see if someone is going to use the new ecoboost fiesta motor, 3cylinder 100 hp plus motor that will fit in a suitcase

Ive only seen one, but it was a smaller harley motor mounted on the nose of a plane (ultra light)

Maybe we can get him to do all the research for us... But seriously, it depends on whether you want to spend a lot of time doing a retrofit or get back in the air quickly. The HKS has a lot more support than any of the other 4 stroke options except the 912 and will get you back in the air quicker. Engine mounts and cowling issues aren't as big a deal.

Possibly George he wanted options, just throwing some out there, the bigger the " box" of options, the better chance one has to meet their needs, financially, time, ability, as for research boeing uses inline 4 cyl. auto 2 liter motors on one of their hydro planes, experimental yes and of course Boeing has allot more in their " experimental fund" then we do, it's no different then the geo conversion with exception to injection is more common now then when the geo's where first used

There is another option i just remembered, Larry Smith uses an industrial motor with his own redrive and his own prop ( culver) on his " backyard flyer" i havent followed what he has done as for engine options on heavier then ultralight planes, but he can retro fit a redrive system on just about any option you choose
