Hy.
Im sory to crush your drams of EZ flying.
but it seams like re-run of some old tec.
But thouse aircrafts where scrapt in the 60.s
fuel eficiency is ****.probably just made up too.
Reason they are ther for a while is that they
didnt do anything yet.(test flight video . Haaa...)
all you see is an fast lo quality video from 60s?
, **** made web page.
,no prices.photos,who? what? why?....?sitem? who?
milatery would made an sistem already if it works.
gaskets had to be changed every flight .
no way in hell.
you have more chance of making an helicopter
out of your own concept.and make it air wordy
out of your garage
Im planing to build my own for 10 years now.
RotorWay International - Premiere Kit Helicopters
and gave up on it.
for reason :
experimental,home build .... have flight restrictions.
if you can fly it only over desert -Why bother.
easier to by normal one.(eurocopter,bell,...)
good luck
