It was interesting to check out their technical specs and safety info on their site. I originally thought that the ballistic 'chute was to help quickly clear the apparatus. But apparently it is helpful for quick deployment at low attitudes giving it a wider range where you don't have a lot of time to let it unfurl unassisted. Cool.
I see the entry of "Useful (Pilot) Load 280 lbs ". I'd like to know what the pilot weight consists of, equipment-wise.
It looks like the FAA maximum amount of fuel that you can carry is 5 gallons, and still be considered an ultralight. It would be nice if they could change legislation to allow for more.
Current range is 31 miles with a load of 5 gallons. Gasoline weighs a little over 6lbs/gal. So, 100 lbs of free weight would give me 16 gallons, which would translate to 496 extra miles of range (minus whatever the extra tank would weigh).
