Ok we did a quick shakedown flight of the ZoPL Endeavour, and it still needs some debugging... but here's the flight. The primary problem was Lack of RCS and not enough Oxidizer. The lack of RCS made re-entry... interesting... and the range is limited to Minmus (for now). Also a problem are lack of landing legs, making (survivable) touchdown on minmus impossible. ALso interesting was that the ship was launched in 0.19.1 but landed in .20.0.... so not sure where that fits. Also it landed with plenty of jet fuel to spare so it can be easily flown to KSC. It also has two refueling ports on the sides for land based refueling ships.
