Hello fellow Kerbals! I'm new to the forum but I've played KSP since 0.9 and picked it up again with the launch of 1.0. I've never showed any of my crafts anywhere and this would be a good place to get some feedback! I've designed quite an efficient lander in career mode (early/mid-game). The lander itself has 2500m/s delta-v and weighs 6.6 tonnes. The middle stage: Consists of 9 mk1 liquid fuel tanks (since oxidizer is not needed for LV-N engine) and an LV-N engine. It makes for a very efficient transporter in space. The first stages consists of 6 large tanks with strong thrust to easily get it into orbit and out of Kerbin's gravity. The first manned mission to Duna went great and reentry to Kerbin worked without anything overheating.
