SSTO Space Plane Designs

[TheGrim]

I am designing an SSTO Space Plane to travel to different planets but I believe I am putting too much thrust because when ever it gets off of the runway, it flips end over end. Is there any way I could solve this or any design ideas?

Without seeing your design nobody knows. There are dozens of possible reasons why your 'plane' won't fly.

Upload a screenshot with the CoM and CoL markers visible and perhaps we can diagnose what ails you.

No such thing as too much thrust!

If you're flipping, then you almost certainly have the CoL ahead of (or on top of) the CoM, which will make it most aerodynamically stable when flying backwards (or in all directions).

Post pics, then we can help. Too many variables to guess.

Either eddiew's suggestion (bad CoL placement), or you have a hell of a lot of aerodynamic drag ahead of the CoM.

Off-axis thrust is also a potential cause, but a less likely one.
