Lofty, I don't know how it works state side, or Europe for that matter, but here in
we have a max all up weight of 600Kg for any compliant gyro, single or 2 place..... with floats, it can be 650Kg. That is a blanket MTOW, nothing heavier (gyro) can be flown here in Oz. The BS to go thru to make anything conform to full registration would be astronomical.... so factories can pump out heavy machines, they just wont fit in here in
unfortunately
I reckon the average Aussie pilot would be 110Kg, ideally about 90L of gas would be good, so that is about 63Kg, so really, any 2 seat machine needs to be no more than 320 (ish) Kg or else it is just a long range single seater, a short range (joy flight) 2 seater.... or just flown illegally like all the rest are at the moment
