Hey Ed, if I bought a JBA 0.56A and shipped it to you new in the box, would you write up a review (just a new post here in the glow forums) and then just send it back to me when you're done with it? I'm not looking for "War and Peace," maybe just some comments about break-in and flying along with some rpm readings of a few different popular 11" and 12" props.
I think a lot of engine enthusiasts would love to hear more about the JBA engines, and I'm sure I could find an airframe for it once you were done playing with the engine.
Of course, there is this review out there:
