Sorry about the confusion, I know I said earlier I have power problems but I actually have mass problems. I was able to find a Thruster upgrade now that I could fit but most of them says mass exceeds limit or something.
Edit: I think you are right MrTact I was probably looking at the wrong class thrusters which is why I couldn't find one that fitted the ship
Vall I will upgrade the power distributor as soon as I find one at a station that is better than what I have installed. All the stations I've been to tonight sells the small class 2-3 stuff.
