Sky Rangers have just had their seat loading increased, although I forget the exact figure. It's something over 100kg though.
They are a very capable microlight and can be picked up for around £20k with a Rotax 912. Running costs around £15ph wet and performance comparable to/slightly better than a C152.
I saw a Samba at the weekend. Its just a bit too heavy to make the UK microlight register at the moment and the one I saw was on the Irish microlight register. What a stunning looking aircraft.
