Good for you ozzi.
For sure you never say "ultralight" because if you do!
They get scared and they'll refuse to sell you anything.
By the way! I fixed one of my leading edge very easely. It took me like five minutes to get it right with the carpet methode from Dale.Thanks Dale!
But the other leading edge was much more complicated.
I could not get the bend right where I wanted it. and ended up folding it too much so I had to bring it to a friend of mine that as a break to get it flat again. But than we maid some creas in the sheet metal so I still have to try it again.
But I am sure that with new sheet metal it would be very easy to do, once you have located where you want you radius.
I was looking at a frensh site it is called APPULMA.
On their link there's a site that was talking about an electric back pack for paramotors and these guys get fouty minuts for 90lb of trust for sixty somme pounds weight of total equipment. So! You know we don't need the big hoop around the prop and the motor weight is wayyyy!!!!! less which lives lots of over for battery weight.
fourty minutes is a lot.
Bob Bouche is an expert at electic systemes of this type. He ownes a conpany called astro flight which sells high performence motors and controler for big models. he would know what controler to use on that type of rigg.
Thanks!
