I have a small recording of what happens http://youtu.be/M3Mz_owN1tA It's 4 atomic engines, connected to a 4-to-1 adapter, on the bottom are 4 decouplers and then another 4-to-1 adapter When I hit spacebar to start the atomic motors, they simply separate from the ship, what did I do wrong? edit: Answered, the solution was to rotate each engine
