I've had pretty good success with basic ship design and getting my landers to Mun and Minmus with enough fuel for the return trip to Kerbin. But I'm having trouble building ships that have separate landing and return stages. My goal was to build a ship that used a Command Module (CM) as transfer/return stage for the trip to and from my target. Once there, I want to separate a lander for trips to the surface and back. I am using single Kerbonaut command pods that I will transfer between lander and CM as needed. I was able to get my transfer vehicle and lander to Munnar orbit and separate the lander. As I was controlling the lander all the controls and NaviBall were reversed. ???? Any help or suggestions are appreciated. -m
