I actually learnt to fly ML when I first returned to flying they are not really any different from an SEP just require a bit more attention on energy management and the AX3/2000 are very low to the ground.
I learnt with Flylight who are actually a first class set-up and and what Paul Dewhurst does not know about ML flying is not worth knowing hence why I wanted to do a course with them.
PilotMike I will look into what you said, very usefull.
