SSTO runs out of fuel.

[Barrrrry]

Hello all!

I am new to the Kerbal forums, but have been crashing rockets since April 2015. I have recently been working on flying a SSTO, and have been having problems. I generally will get to a 70-80km orbit with no fuel left over. I use either RAPIER engines or a mixture of Ramjets and aerospikes. I generally fly a flight profile with a 30-40 degree climb to 10km, then I throttle up to full and go at about a 2 degree AoA. Once I hit about 1km/s speeds I pitch up to about 30 degrees, raising apoapsis. Can you guys/gals help? I don't know what I can do to save more fuel. 

Thank you in advance!

Also, sorry if I placed this in the wrong area! If I have, will somebody please inform me as to the proper place to put this?

Moar boosters. They solve everything.

Yeah, this should be on the "Gameplay questions/tutorials" board. There are a ton of people willing to help with SSTO's.

Thanks Kerbonaut

You are pulling up too early and too violently.  Just fly at you angle of 2* and you should get up to 1400m/s and only switch rockets when you are losing speed.  Pulling up adds huge amounts of drag and 1km/s is rather slow for jet mode.

Thanks! I'll make sure to apply that.

Since this is asking for in-game help, the thread has been moved to the Gameplay Questions subforum. Good luck with it.
