Hi!
Reminds me of some of the movies from the thirties in which persons was trying out new inventions.
Remember one "helicopter thingy" powered by a big V-8 or was it a Gnome Rhone rotating engine with a big parasoll flapping above...

Hopping and jerking around tossing the pilot out before it shook itself to pieces!
Hope this will work out better...!
Regards!
