Chuck,
I'm liking the stabs in the rearward position a bit more than forward. Feels like a slightly longer tail moment. It's been windy so haven't had a chance to really wring it out with some 3D. I can tell that the rear position would be much better for IMAC style flying and the plane feels like it tumbles a bit better when the stab is in the forward locaton. I'm sticking with the rear position for now as it feels a bit better. Time will tell as I get more flights on it... Honestly - it's not a drastic difference between the two, but I'd probably recommend the rearward position as a start and if you want to experiment - try forward later... So far - it hasn't hindered or improved my flying - just a different "feel" to the plane that is subtle.
