I'm fairly new to this mod but, is there a way to use cranes/wenches to get >1t parts into place and then use scaffolds to get a kerbal in position to weld it in place? I am hoping to manually build vehicles on other planets part by part. Rather than Konstruction's option to pre-build the part and pack/unpack it... Also, does lowered gravity increase the weight a kerbal can move? (ie. can a kerbol lift >1t on the Mun?)

Hey, noob question, but, is there not a way to plot between a planet and a moon? I can get a plot between moons or between planets, but not from Kerbin to the Mun...
