Dragonfly Microlight

Came across this the other day, while looking for something on the interweb...
Flylight have taken advantage of the rule changes for Microlights in the UK, and have produced a small lightweight 1-man trike and mated it with an Aeros hang-glider
I wont bore you all with any more 'techy' details, about engines etc etc
Great video though...and yes, it is fine to switch them off occasionally as long as they restart OK!
