P.S.
G, Not my heavy old S6-116: I was referring to my miniature Cub 'look alike' Rans S4. Now that is a real microlight, max AUW with fuel and driver is 587 lbs.
e.g. On take-off, if not held down to nearly 30 mph, it can float off far too slow to be safe & where any light side wind component has a disproportional effect. Much the same as when landing.
A glide approach is of course possible, but means quite a steep dive & isn't so easy to make the desired touch down spot. In all instances with a ridiculously short landing roll a regular powered approach offers much better aerodynamic control and the rudder/directional control.
In fact all I'm saying is that for the P1 to operate safely & in the sweet spot of best control there's no sense in discarding the benefits of power.
