Not sure if this challenge has been done before, but I've been fascinated with Duna lately and stalked these forums long enough. So hello everyone, Rockytop here... nice to meet you. Challenge is simple... who can land the heaviest space plane on Duna. Rules: Horizontal take off Horizontal landing All stock parts. Mechjeb allowed. All parts that you start with must remain on your ship throughout the entire flight. No disconnecting any parts during flight. Jet engines are allowed. No parachutes! No engines pointed vertically... (basically point your main engines horizontally) Props if your plane can take off from duna and come back to land at Kerbin. Regular Ranking system based on weight of craft once it lands on Duna. Secondary Ranking system based on weight of craft once it lands on Kerbin if you are so inclined. I realize I am new to the forum, but I have done this before on Duna, never taken pictures though... gonna try out a new design and see if I can land it today. Ranking: Weight on Landing/Name 1) 12.34 tons - Rockytop00
