Question: ksp must have mods reddit?
Answer: Hangar extender really made my building process run smoother! "Kerbal Engineer Redux" "Better Burn Time" "Maneuver Node Evolved" "Better Time Warp" "Kerbal Joint Reinforcement" Those are probably the most useful mods that i've used so far. Later on you can get "MechJeb 2" if you're getting tired of planning maneuvers.
