I like small, minimalist airplanes designs, but you keep referring to your designs as "microlights". Unless Romania has some very different rules, none of these designs would fit into any microlight category I know of - way too little wing area/too high a wing loading. "Microlights" or whatever they coose to call these types of aircraft in most European countries are limited to wing loading of around 5lbs/ft or around that figure. Yours are more like 8.75 and would never meet these criteria. Still nice design ideas, but firmly outside the "microlight" area. Like the Cri-Cri, which many people refer to as an ultralight or microlight - way too fast and too much wing loading to qualify.
