Hey triple x again yr dreaming there buddy more HP, cheap operating costs pale into insgnificance when it all stops mid flight, that's when you wish you had paid a few dollars more for peace of mind
Safety costs when it comes to a man in a plane/coffin & you could even get the cost almost down to zero using just a rubber band for power but what happens when the turns run out?
By the sounds of things the Jabarubberband can't keep yr world turning 4ever
