Space plane wing area and hard to rotate


Recommended Posts

My CG and CL are close together, I have 120 ton takeoff weight+23 wing area. I have two regular elevons+1 standard canard on each side. My space plane flies well, but I am having a hard time rotating it. Is it because my landing gear is too far back, not enough pitch control surfaces, or I don't have enough lift?

  • Landing gear looks to be in a good location, but try moving it forward if you can.
  • Move the canard pitch surfaces farther forward, closer to the nose.
  • The elevators should be larger, and mounting them farther aft would also help.  For a plane that size I would use the Big-S elevators.

You seem to have zero AoA, meaning that your wings are producing no lift on the runway. That will make it very hard to lift the nose up with just the force from the elevons.

Try using the offset tool to raise/lower landing gear as appropriate to that your nose points up a bit when on the runway. Also consider just giving your wings some incidence,
