Builder ship will not engage travel drive when piloted - Resolved, misunderstanding

[Airc777]

I can't tell if this is a bug or a game play feature that I'm just not understanding but when I try to manually fly my Heracles Vanguard and enter travel drive it just doesn't. Or rather, what's happening is I push shift+1, the window changes to the travel drive color, the audio que plays, and then the ship continues to sit at a maximum speed of 107 m/s indefinitely. The ship is fully crewed and I don't really know what could be wrong, it has Argon travel drives. I then tried standing on the bridge and giving a dock-at order and then it worked properly, one of the crew npc's said 'engaging travel drive' which is an audio que that did not happen when I just tried to hit shift+1. I know flying the builder ships is probably not the most fun thing to do but this was my first L or XL ship and I was excited and I wanted to manually move it from Sacred Relic to Argon Prime where I was going to buy escort fighters for it. Now I'm kind of sad.

Edit: Never mind, I'm stupid. I was confused by the long travel drive charge time, the amount of time you have to have the ship pointed in the same direction for the travel drive to start charging, and the lack of and audio que to let me know the drive was still charging.
