I did a sustained turn test with it, on the deck, with fuel for 20 mins.
Does a full circle in 13.6-8 seconds without flaps and around 16.0 with full flaps. Its pretty much between the a6m2 and the a6m5, a bit closer to the later model, but it depends on pilot, the difference is as little.
Turns better than the brewster, rolls really well around 200mph, loses a little bit at real slow speeds but still remain nicely controllable even with flaps out. Its a huge improvement over the a6m2. Its easy to perform the hammerhead reversal with this ride, and it can do the tailslide too. Remains controllable til 400mph without adjusting the trims. The climb performance is excellent, around 3400 ft/min on the deck. What you have to watch: unlike the a6m2, it loses a lot from its turn rate at real low speeds if you dont use the flaps.
I would take this ride against any other zeek, brew or hurricane.
