Thanks MarK!

I have the same types of problems that Ed has. I haven't done any inverted snaps yet, and I haven't been able to get it to spin at all. I have only been flying the model 1 season, though. I have noticed a lot of coupling in stall turns and generally as the plane stalls and pivots I have fed in full opposite aileron to keep it level. Mine flys hands-off inverted. Knife-edge is terrible because of coupling. I roll in and add rudder and it tries to pull to the top. I push in down elevator and it tries to roll upside-down. That's usually when I give up!

I just got a new Futaba 7 CAP and am planning to try mixing some of the rudder-aileron coupling out. The manual does make some suggestions about this although I can't recall the exact numbers. I'm hoping it works.
