I decided to mess around with spaceplanes; but no matter what I do, how many different control surfaces and winglets I add, as soon as I pull up even a little after getting to speed, I loop around and impact the ground at fatal velocity-if I'm not doing cartwheels on the tarmac instead. Help!

Is your center of lift too far away from your center of mass?

[tryrar]

nope, I made sure to match my center of lift and mass

[forsaken1111]

I get best results putting my center of mass forward of my center of lift actually. Not FAR forwards.

can we get a screenshot of your spaceplane?

[jocan2003]

Center of thrsut AND lift has to be well placed, if your center of thrust is *under* your center of mass you will flip up

[Girlinhat]

Also be sure you have enough speed.  Trying to take off too soon can result in a flip, you generally need 150-200 speed before you can safely lift from the ground - usually at that speed, the plane starts to lift itself.

I tried to make a VTOL with rotating motors.

It ended badly.

a mod that gets you out of warp before soi changes or nodes. changed my life

Wow ok i think im a good aero engineer then... i made a plane that take off at 50m/s, is stable empty or full and weight about 45 ton i think when full? the TWR is about 2ish ( when full with kethane).

Yay, just had my first successful interplanetary flight. I decided to build a design to be very simple, rather than overcomplicating it, and I managed to get to Duna after some Maneuvers of Dubious Efficiency.

Having a little trouble orbiting my Munar lnder to the return vehicle.
Guess two poor Kerbals have to remain in Munar orbit until the space agency is done with it's Minmusmission

[tryrar]

Goddammit I was all set to match orbits with my station core for try 1267 at docking, when suddenly one of the engines cuts out. I inspect it and notice the fuel line for that engine that goes from the main tank to the smaller secondary secondary tanks the engines are attached to, isn't actually attached to the engine, but to a radial mono-propellent above it.

You can transfer it manually.

BEST MOD EVER!!

With that no more fuel line between tank, choose what tank is use first even if it doesnt respect stagings etc. Fuel management? Thist does the job.

A tail with tail fins really help a lot with stability: It's very much like feathers on an arrow.

Also, pictures! even failed designs are fun to look at!
