This dvd was released by Foot Flyer (powered paragliding people) but nonetheless it can be a good addition to any pilot's collection.

It was the fifth year of the crazy action wich is called "Flight over La Manche canal in Slovakia". It flew 33 machines. It is very funny adventure for MLtrikes and powered paragliders pilots and it flew on Slovakia only :) But we have all...and rescue boat too :))
How about a trike trainer on a string? This one is a wind powered trike, the string might not be included :-). Anyways, I want one too. I bet is a lot of fun and cheap to fly, as long as you don't have to pay the "string guy". Fly Safe!
