This is a really nice pack, thanks. I would like to add a few suggestions though that i think would benefit this pack and the game. - A 4 socket to 4 socket coupler (for center rocket reinforcement) - A single 1 to 1 coupler or mini fuel tanks the same thickness as your couplers to keep the rocket parts at the same level. - 2, 3 to 3 couplers ( one in a row the other in the normal tri shape) - A 4 socket to 1 (like the first one but for connecting to large parts) - longer fuel tanks (double, triple or quad the size and do the same for weight, just in 1 model) - if doable a thruster module to put more force on turning the rocket in the desired direction. - a longer radial decoupler (like 2 connected with a beam maybe?) that would attach and keep things more ridged.
