Hello, everyone! I have been wondering, what's the cheapest thing, that can go to orbit. I have tried a few designs myself, but I want to compare them to others. The challenge is to spend the least funds to go to LKO (low kerbin orbit). It must be at least a bit over 70 km on periapsis. Recovering parts doesn't count. I would like the vesels to be from 1.11, but other versions are accepted. There will be two main ctegories: modded and stock.  Stock:  1. 690 by Dvader
