o.k., so we can ignore the gyroscope. it's basically zero-grav football, with the addition of foot-rockets. I can tell ya right now that won't work. ya put rockets on an human, in zero-g, that far from the centre of gravity and it will just spin around the centre of gravity at high rotational rate, whilst bouncing off the walls at high speed, with serious damage to itself. absolutely no control whatsoever. instead, you gotta put weights on 'em and let 'em use their legs to push off the walls. no rockets.
