¡Hola! KSP is amazing by any standards, and I have done a lot so far. Some good advice? Well, don't be afraid to build huge rockets; I know I was at your time. The Kerbodyne tanks and engines, if you have them, are amazing in every way possible. Also, in 1.0 a new "Engineer's Report" button was added to the VAB and SPH in the bottom right-hand corner. Trust me, this thing works wonders, and after fixing all the problems on your craft you will fly safe. Welcome to the forums, I hope you enjoy it here!
