ChillLander

Hi, i love this game, i played the demo and now i bought it, i´m trying to get into orbit and to the Mun, but when i finally get to it i realize that i need more batteries, anyway, that´s not the deal, the thing is that now i cant get into the orbit with heavy lifters, i wanna get first into the orbit so i can get into the Mun with enought fuel to come back, just a flyby, not really trying to land there yet, any advices?
