I tested the weapons and did not find any power problems firing missiles, cannons and moving at the same time. As Omega said there is a high initial drain, but the ship never loses power completely, and recharges fast.
The raptor’s weapons need to be improved, and a little more detail on the wings would be nice; however, this ship is agile and has a stunning interior. majQa'!
The torpedoes drain the power of the ship when they are fired even when the ship isn’t moving; this ship depends on its manoeuvrability to survive in a combat situation, and when firing a torpedo drains all the power, this is a major problem.
