Its definitely different than flying a glow .60. not better/worse, but different. You'll see what I mean when you fly it.
The discussion has been that the 10gx is equivalent to a hot .46 sized engine. I think that is on the modest side, its definitely stronger than a .46. It will fly your .60 size plane... but think scale flight, not 3D.
as for the backwards running engine interest.... Im interested. This engine would be a perfect match for all the old royal twin kits. Which probably means realistically there is at least 4-5 people in the U.S. with an interest

I doubt the interest is high unfortunately... but I'm wishing I had one.
