This is a better version of my original SCA, in which you can actually control the shuttle after detachment (if you want that one, just got to Switdog08 > View profile > View posts > then click NASA 747 SCA). The differences & improvements are numorous. I made some changes to the gear, re-scaled the engines to be more like the real plane, several esthetic changes to the shuttle, I moved the shuttle farther up on the plane's back to be more like the "Piggy Back" position of the real shuttle. And for those of you who didn't like the complication of controlling plane and shuttle at the same time, I deactivated the shuttle's airlerons. You can still have fun watching the shuttle climb instead of glide, (last version) since I added a main rocket to the back (dont worry, it doesn't activate until you detach. For best results, turn on autopilot before detachment. Comment for more ideas, and have fun!
