Defkaunta

Hey, thanks a lot! I will try it out right away! One more thing. I cant seem to find an adapter part which connect the circular "tetragon projects" elements with the hexagonal "tetragon projects" parts. Is that normal? Or maybe i missed it. How does the part look like? Thanks!

This might be a very stupid question but i recently added this pack to KSP. I am building a spaceshuttle now with the Tetragon Projects "Sabre S" & "Sabre M" Engine. I have added fuel tanks and air intake. So far it starts without falling to pieces but as soon as i reach the stratosphere (border to space) one engine after the other switches off and my spaceshuttle falls back down to the ground. Did i forget something? Are the engines not made for space travel? Any help would be great! Thanks!
