And one other idea What do you say if you can ask researchers to design your own ships based on known researched weapons and technologies Exm: you know about level 2 turbo blasters and Ion gun level 4, shields generator research is on stage of future research of level 3, hulk material is on level 2, power generator is on level 5, hyperdrive on l2, cockpit type on lv2 etc - you ask your shipdesigners to prepair a new type of ship - let call it X-Wing Model 3 Even more interesting will be if you can make a model by yourself
