Great job Andy. Do you have the tray attached to a servo? I've been thinking that our pattern planes are so stable that when it is time to do a stall turn into a spin. I'm sorry but after flying RC and pattern for 30 years I have not yet to seen what I would call a stalled tip true spin performed by the planes were flying today. I would even say that when watching one of our F3a USA team members practice here at our field and he flys a biplane. Maybe by setting up a servo to the tray you may be able to set the position of the tray into a more unstable condition thus creating more of a pronounced spin and not so much of a spiral dive, then switching back to stable. Just an idea I've had in my head and you actually came up with what I also envisioned.
Beautiful plane and you have done an excellent job of setting it up.
