I have been kerbaling a few months now, and LOVE IT. But I feel I cheat a little to much to get to the MUN. Because when I download awesome packs like Kerpollo and White Monkeys able class rocket I have to add big boosters and sometimes swap out engines. I assume the packs are designed to get there as is, so what is my issue? I have tried the slingshot around kerbin, doing short bursts of heavy burns and 'leap frogging' but I just cant get it. HELP PLEASE Bob and Jeb want more of a challenge. Thanks, Subfreq
