Bobby,
The Dyke Delta, like most delta wings, does not stall.
Although, most Dyke Deltas have a minimum controllable airspeed of about 90MPH, more or less depending on loading etc.
If they get below this speed they will tend to start to Dutch roll like a falling leaf and rapidly descend at up to about 1800 fpm.
