I believe thats what they are called... I'm pretty good at making rockets, and complex structures but I cant fly them! I can barely get into LKO, but its terrible and uneven (I didnt use nodes). Trust me, I've watched alot of videos and I cant figure out how to make a node to tell help me get to the mun, or LKO. If anyone can help me it would be appreciated. Thank you very much Cheers!
