Just my twopence worth...
Many years ago I owned & flew a Pegasus-XL flexwing microlight.
Approach and landing were easy in good conditions. At the right point in the circuit the engine would be brought from cruise to idle, simultaneously the bar was pulled in, the target airspeed was 45 to 50 mph on the approach to give plenty of energy for the flare and landing. Keeping the airspeed up also made roll control just that bit more positive.
Due to the low weight and high drag the float was very short as was the ground run. The stall speed one-up was around 25 mph so I was usually doing 1.8Vs to 2.0Vs on the approach right up until I flared for the landing.
On one flight my ASI failed which was pretty much a non event.
The point is that the approach/landing technique on that aircraft was very different to that from heavier aircraft such as a PA28-161 which I also flew.
