I flew a flight test of the Balerit for a flying mag years ago. It was the nearest thing to a foolproof aircraft (if there is such a thing) that I ever met. Stick back in your gut, boot in the pedal (no ailerons) and it just went round the turn nodding gently but impossible to stall, and I tried! Anybody trained on it would have been lethal on anything else.
It's only problem was crosswind landings. Couldn't yaw it straight as it immediately rolled away from the wind. Couldn't use wing down technique as no ailerons, so just had to put it down and let the undercarriage take the strain, which to be fair, it did. It was just a microlight with tandem wings and therefore lots of drag with all the struts etc.
