Flying in your lazy chair
Imagine a drone with eight motors and fitted with a chair. That is a succinct description of what a Swedish designer has published on his YouTube channel. Eight gasoline engines are attached to a light-weight frame onto which is mounted a light-weight chair with seat belts. He hasn't dared flying higher than 5 meters, since the control is rather difficult. That is because the motors don't react as quickly as electric motors and that makes fine control very awkward, witnessing the various crashes that the vehicle has already experienced.
