I'm glad to introduce Super Jello Killer.

DadHav has been my main source of inspiration:

Plates are hard wood, 50x50x10mm for version A and 60x50x10mm for versions B and C.
25mm long 3mm carbon fiber rods are glued in 3mm holes.
60mm long pieces of 5.5x2.5mm silicon fuel pipe are slipped on rods on versions A and B.
50 and 70mm long fuel pipes are also tested. Version C shown has 70mm fuel pipes.
Cameras attachments come from Mobius Helmet Mounts.

Version A: 75g - with Mobius: 125g
Versions B and C: 90g - with Mobius: 140g

It has been tested on a much used quad with worn bearings, one bent motor axle and no balanced prop, giving a lot of jello with rigid camera mount.
Super Jello Killer effect was clear, there was no more jello.

My previous device, made with rubber bands, was also working well but it was larger and lacking fast setting of camera's angle.

Hoping this could help users of less than perfect multicopters.
