Re: [460] Rapid ascenders
There's a gas-powered civil version. 3000 ft on 1L of fuel (unlike the electrical version which does 900ft on a charge)
http://wesspur.com/ascenders/wraptor.html http://www.actsafe.se/.../pme-power-ascender/ I think that there is really no reason for quietness in a civilian version, that's why they're all gas-powered.
I would be awesome to hook one up to an A and make an A-boogie, it can lift 2 people at a time!
edit: Oh, and for the really sneaky people, the battery powered version with remote control
