"It sounds like a classic 'downwind turn stall'. It happens in full-scale as well"
Just not so, not at all. If it were so, every time a boat is turned "down stream" it'll get swamped. Relative wind is relative wind, ground speed and airspeed (true, indicated, or calibrated) are not.
Sounds like your DB was too slow in the turn with an increasing load factor leading to a stall, a great classic pattern ship, hope you're able to put together another one.
