It always fascinates me the number of continental microlights where the stall speed is always exactly 65 kph.
I have heard "reliable rumour" that there are two French microlight types approved in the UK, both of which only when properly checked are only microlights under the British 25kg/mē definition and not under the French 65kph definition - but the French do have a track record of looking the other way to benefit their domestic industry.
