Help with MechJeb, wont limit my ascending speed...

[OptiSTR]

Im trying to set ascending speed to 200ms, but no matter what i do it still goes above 200ms and maintain 100% engine thrust.

Help please

Problem is that im trying to fly a pretty big rocket, with a space plane attached to it, and at high speeds withing the atmosphere it tears my plane appart

If you used the "Ascend Guidance" autopilot then there is no function to limit the Ascend speed to a specific value. You can use "Limit to terminal velocity" but that would be around 250 m/s for the first kilometers, then there is "Limit acceleration to" X in m/s² that would limit how fast your rocket accelerates, you could decrease that value until you are out of the thickest part of the atmosphere, try setting it to 14 m/s².

Other than that I can highly recommend the Kerbal joint reinforcement mod, it sets the strength of the connections to more realistic values.

What if you limit the acceleration to 0m/s or 0.1 when your at your desired speed. SHOULD hold your speed then
