  1. Like I've been able to take kerbals to Mun, Minmus, but I've been struggling to build a spacecraft that is able to take Kerbals to other planets. I wanted to build like a modular spacestation/craft like the Hermes that has its own farms and is self-sustaining to a point. But can be very difficult and it falls apart. I also worry that cutting down on my mods will destroy my relay sat infrastructure. 

  2. Update on my Lunar Basecamp. Unfortunately don't have screenshots and will send them later. I landed the green house, rover, and habitation model. Used some of the external experiments from Breaking Ground. Currently I have two crews at the basecamp, both landed with the soyuz-fregat lander. I want to slowly faze it out with the new LK-700, but I don't want to have to leave the landing stage. It creates for obstacles while landing and contributes to trash near my basecamp. I hate SSTOs, but I'm unsure on how to proceed. Any advice?

    I've got this design working a couple of times, return and all, I will try grab you a craft file :)
    IIRC you must double up the fregat, and use the first as a "crasher stage".

    Thank you! I appreciate it. I really do appreciate the Lk-700 Design, but I want to the use the command module as an orbiter and later lander. Want to try to challenge myself. Any thoughts on the disconnected lunar base camp idea?

  4. Okay okay okay, sorry for  bothering everyone put I'm building like an international Mun base camp? Not connected buildings but a bunch of like smaller buildings with some of the new Breaking Ground Parts. I'm having a lot of trouble finding a way to land more than just two people on the moon without using one of the stock command modules. I REALLY to want use the three-man soyuz module and build something like this. However, every time I try, I never have enough fuel to get the craft back to Kerbin. Any suggestions? Also, does the base camp design of the base sound bad? I wanted to try something different than Planetary Bases. Also Ik about LK-00, but I wanted to use the Soyuz first.

    @RaiderMan The design of the spaceplane may objectively be very bad. Answering someone's query for design help with an autopilot mod is not the way to go. It does not help the person to design their craft better, and if the design is poor enough then the autopilot will miserably fail.

    @Callistoan Your spaceplane design was objectively bad. I removed the forward service bay as it contributed the most to omni-directional body lift (see light blue aero effect lines in album) and replaced it with a down-facing extra deployment bay. I raised the main wings to raise the CoL to fortify the plane against flying upside down, and added some loaded Ore tanks to control the CoM (since these wings are heavy). I then added some down-facing stabilizers to increase very badly needed yaw control (see omni-directional lift problem), and I removed the elevons from the underside of the aerospike as they lower the CoL and make the plane want to fly upside down. Also, flaps around an aerospike sounds wrong to me-- especially when the aerospike rightfully has gimbal and lots of it.

    Finally, I added some stabilizers (as canards or forward flaps) to increase the plane's forward pitch authority which is also needed very badly. Note, I keep these wings dry. I don't like clipping things into loaded tanks, and the wet mass CoM offset is not worth the dV. Pitch authority lies equally in an aircraft's ability to force its tail up, and its ability to force its nose down to resist flipping out at high AoA. Either have canards or (preferred) have lots of rear control surface area near the CoM. I no longer needed to empty my RCS to guarantee a stable reentry.

    It's no longer the shuttle you may dream of...but it's a stable one and not that much bigger. You could skip the down-facing yaw stabilizers and pack more RCS fuel or more sideways RCS thrust to compensate.

    Thank you so much omg! This is my first spaceplane (since I wanted to use the pack with it), and I really appreciate the constructive criticism. Btw, how do you add the ore tanks to the wings? I'm still not sure how you do that? Also, how much fuel do you suggest I keep in the tanks.

    So I built this spaceplane and I've been having difficulty during reentry. The vehicle starts to go all willy-nilly and turns over and I can't pitch it back correctly.I have three vertical stabilizers, one on the main body and two on the wings. There are control surfaces under the aerospike. Should I launch it with a rocket or by itself? Every time I have tested it I just used the cheat. Please help.

  8. I am very confused about Polyus. I know it had an FGB module to dock with, but what was the purpose of the larger black module. In some pictures, I've seen it as some sort of laser cannon while other show it as habitable space. What was at the end of the polyus spacecraft. What were the two radial tanks on the side for? Where are the engines that they had to use? Like the little engines on the Salyut?
