I was wondering if anyone was doing a heavier setup on a trike or quad frame with additional battery packs for longer flights. The Ozone Triox wing is rated for up to over 800lbs. You can be up to 254lbs for a 103 ultralite. That gives you around 500 plus pounds worth of people/stuff you can take off with.
I figure a trike frame of around 40 pounds, the new SP140 is 31 pounds, so that leaves around 180 pounds for batteries. Each 4kwh battery pack is 40 pounds, so you could have 4 of them on the trike.
Is anyone doing something like this already? Or am I missing something that makes this not work? Obviously that much battery is kind of expensive, but other than cost.
