I don't know what frightens me more - the cheap, supermarket-style, plastic fuel container, that obviously has passed muster as a fuel tank (please tell me, it's fuel-rated plastic) - or the frightening multiple-belt tail rotor drive system that reminds one of a flat-belt-powered machine shop, of pre-WW1 vintage.
I reckon the life of the whole unit, including the operator (I wouldn't dare call him a pilot - a circus daredevil, would be a more fitting term) revolves around the life of the plastic fuel container - which I would estimate at 3 weeks maximum - and possibly even considerably less, if subjected to strong UV light .....
