Good point, but nope, nothing like that going on

Very good point, but probably blunted by the lack of detailed regulation
over here... basically if the public used it it would be illegal for them to do
so
anyway and any pro's buying it would have to make their own assesment
before using it in any situation where the public are exposed.
Nothing to stop them claiming lack of safety and trying to stop sales by
reputation
though.

I must leap to their defence here :)  the reprogramming service is only provided
for those who want non standard timings on the sequences (it comes pre
programmed
with IMO rather boring equal times between firings from 100ms up to 1s, with
my mod you can do some nice accellerations etc) The reliability of the stock
product is fine.

We've only had one 'show stopper' and that was due to an igniter wire not being
tied down and the whole lot got launched into the air with a shell that decided
to
take it's match with it, that pulled out all the other wires and made the
battery fall out
so at least it failed safe :)

I suspect you are entirely right... it's great fun though :)

Cheers,
            Robin.
