They microlights fligh over my house all the time (lesmahagow) i so need to tray it some time
Well my dad flys microlights but it all depends because different microlights have different fuel tanks some bigger than others and wind speed as eastkilbo mentioned flying into wind will use more petrol but flying with the wind speeds you up using less fuel
Sorry to disappoint you, but I was just a passenger, so I don't know how far these can go, but I suspect the distance over the ground depends heavily on the windspeed as they're not desperately fast. You should visit microlightscotland com if you want more details.
ive seen you guys fly over airfield where we fly model planes near netherburn (hamilton radio model club) it must be great views up there
