I wanted to build a gps-guided missile with the new physics sensor. It was supposed to be 1 Block thick only. However it is not possible to controll the roll of the missile via the rocket fins block. I expected that the 3rd composite channel to be for roll but none at all. Now i need to put on extra fins to stabelize the roll wich means it`s not 1 block thick anymore.

A third channel for the roll is probably not too hard to add but it would really help with building small missiles.
