SASless,
With the greatest respect to old bones... Have you looked at the latest generation of factory manufactured gyrocopters like the ELA-07 and MT-03?
Both these types have approval from the various authorities and have redressed all of the problems of earlier designs. Training on these modern aircraft is far more comprehensive (in Europe) and better regulated and as such, much safer than before and I think the stat-heads out there will willingly back that up.
The cost alone of these new era gyrocopters has kept out a lot of the idiots that used to blight the hobby with crappy and unsafe second hand homebuilt ****
OK thread creep over... I have'nt got a clue what the original question was
