Help?

I haven't played since .90 Now ever thing I design teeters up and down after take off and crashes. I turned on infinite gas and rcs, designed a bomber. Take off and the plane goes up and down violently and crashes. Any suggestion?

1.0 overhauled the aerodynamics so atmospheric flight is realistic. You now need to make your crafts aerodynamic and sometimes add fins near the bottom to keep your ship stable. No more boosters without nosecones, that also means .

Aero has changed drastically since .90. I suggest building a rocket that looks like a rocket, starting your gravity turn at 100m/s and taking it slow. Planes should look like planes. Post some pics of your cafts and We can give you a hand.

Try checking your Center of Mass (CoM) and Center of lift (CoL). The CoL should be either just behind or on the CoM. If it's not, it's either going to flip over or not lift off at all.

If we're talking about planes, try turning off the engine gimbals. They could be screwing with ur SAS steering instructions if they're mounted near parallel to the CoM.

What the hell is Gimble?

[Ten Key]

It means the thrust vectoring on the engines.

The engines in KSP can move, and SAS can adjust them to try and hold your plane steady. But in certain configurations, this can actually make things worse. If you right click on the engine, there should be a "lock gimbal" option. This will freeze the engine in the "centered" position, and may correct the problem.

It could also be that you have an excessively flimsy structure and/ or too powerful control surfaces. Both can cause an excessive control oscillation.

This just reminded me that the engine gimbal problem I suggested is very similar to another problem caused by pitch control surfaces being mounted too close to parallel with the CoM. Make sure all your pitch control is coming from a tailplane or from canards near the front, and not from anything on the mainwings.
