Replica Launchers [New Atlas V and Proton for 1.0.4]

[pTrevTrevs]

Just use thrust control in the right click menu, as well as fuel level. I also use RCS build aid to figure out very exactly at what percentage everything should be, as this plugin has an engine balancer as well.

For example: When I balanced the 551, I started by divinding 200% (of two boosters) byy three (for the boosters on the other side). Thus I set the three boosters' thrust and fuel level at 66.5%. However, this isn't perfect yet, and that's were RCS build aid comes in for finetuning.

Ah, ok. I think I should try building a series of launchers with asymmetrical boosters.
