One of my very first ships, the Ribcager was originally intended for precision transportation of cargo, but has been used instead as a convenient way to dispose of little buggers, as a small infiltration vehicle, and a parasite of various planes (take me for a ride!) A prominent downside of the Ribcager is that the fuel capacity is sub-optimal (to fix that, just add extra fuel tanks on each end of the VTOL engine or avoid having it on full blast all day,) but it is not intended for long-ranged missions. Use [2] to deploy the parachutes and [1] to allow manual override of the gyroscope for when you feel that the RCN just isn't good enough.
