I feel like my fence is not tall enough all a sudden

It uses a disposable fuel cartridge for the jump ability, which kind of turns me off, but I'd love to get under the hood of the propolsion system and the gyros that keep it stable enough to maintain video mid-jump.

Pretty darn cool for such a small package.
