Hello! First post here. I started attempting this before reading all the info here. After reading, the tip of going full throttle at start to 100 m/s was a big boost. Here is my very un-scientific way of getting max alt, I just kept trying different things. Full throttle to 100m/s hit x and immediately hit shift to increase to the 6 mark on the throttle hold throttle until 10k at 10k, give it a quick bump in throttle repeat for 12k, 14k, 15k and 15.5k gun it to full at 16k This method will always get you to at least 33,400 and sometimes more. The controls aren\'t precise enough to control much more than this. Heres a video! I started recording near the Ap of my best attempt yet (33,513) and then a few more attempts afterwards. <iframe width='640' height='360' src='[url]http://www.youtube.com/embed/4pWdlWBC8CE?rel=0'[/url] frameborder='0' allowfullscreen></iframe> Kerbal Space Program - Goddard Challenge
