Hi there....what did you do to the hinge pin of the lid? Did you cut it off entirely?

The Shz is a flight helmet for wear with or without a bonedome. The big rubber pad is to align it with the inside of the bonedome's shell or to act as a head protector. Pilots who flew MiG 17s and 15s and smaller jet and piston engined trainers and transport aircraft used the helmet with no bonedome, whereas pilots who flew supersonic fighters such as the MiG 21 used the full bonedome. The helmet in the lower picture is a tank helmet, for use by the crews of all Russian-made AFVs. It comes in summer and winter models (more or less internal fur). It has more ribs on top of the helmet and is always black. The green helmet with ribs on top is the canvas parachutist's training helmet.

How much does it weigh?

I did but the shower curtain was too thin for the power being delivered so I used a trailer cover for the second craft, which did work, lifting my daughter easily but is a bit too bulky and not as flexible as a shower curtain. I have seen hovercraft that used two battery powered blowers inside a gymnasium. have lots of fun!
