Piramic

Duna bound to meet up with the lander and station that was sent that way earlier... I modified the adapter piece to work without the LV909 and removed the decoupler functionality. The main engine is a NERVA that has been clipped into the 2.5m fuel tank for aesthetic reasons (I hate how long they are) Weighs 23tons on the launch pad and has almost exactly 5000dV.

I have a very small probe and am trying to figure out of it is more efficient to use a small RCS tank and one of the linear RCS thrusters vs say the ant engine and an oscar B tank... If you dont know, perhaps you can help me figure out a way to find out. Edit: I answered my own question. Small probe body + 50 unit RCS tank and single thruster delta v = 1767 Small probe body + two toroidial tanks and an ant engine delta v = 2283 Both weigh about the same 0.400 for the RCS setup and 0.402 for the ant engine...
