Oh, about afterburners (Combat movement)... you got one big problem with them, only the higest value is used... they DON'T add together (unless this was changed in the Last patch, but I don't think so)... so if you got 5 Tactical Engines each with a combat move of 2, you'll only get a combat speed of 2 NOT 10. Sorry for the bad news.

P.s. You should know that the ability used for solar sails can be added to other things, their are two values given for that ability, one is the speed bonus the other is a unique identifier... you only get the highest bonus from EACH identifier, thus you can make several componets with that ability and their effect can add together (but only 1 is effective for each type = identifier)

just a FYI
