Lol yeah it took a while to make.. Mostly due to the small amount of space inside. If you dl it have a look inside the orbiter and you will see what I mean. And it was done without those new gizmos. It would be a bit easier now. Thanks man, don't give up trying! The Mk.3 parts are a bit big for an X-37b, try the mk.2 parts, they glide very well.
