More spaceplane questions.

Hello all, I'm trying to build a space plane that actually works again with no luck. Seems that all of my planes flip backwards uncontrollably when i attempt to take off. Is this solvable?

Yes, Dont pull up too much, Dont have too-much weight at one end, Use SAS for the 1st few seconds of flight and winglets and control surfaces are your friends.

Thanks, I would go try and do that but I somehow got into making boats...

And don't put the lift too far forward, don't have too many control surfaces and make sure you've got at least as much drag behind the centre of gravity.

It's basically too much force pushing the nose up, either temporarily or persistently but there could be a few things providing that force and it's hard to judge without seeing the specific designs.

Balance seems to be your issue. For jets, the most important thing you can do, is place your Center of Lift, JUST behind your Center of Mass.

If your Center of Lift is BEHIND your center of mass, the more stable and slow moving it will be.

If your Center of Lift is ON TOP of your Center of mass, your ship will be twitchy and extremely maneuverable (and easy to throw into an uncontrollable spin.)

If your center of lift is IN FRONT of your center of mass, it's unlikely you're going to get off the ground at all.

along with what everyone else has said, always put an avionics package on your planes. its a world changer.
