Another STO question

[legion1202]

Build my first space plane and having good and bad luck here. I am using far and a few other mods. I `ve built a pretty solid ship so far. It takes off and can fly so so. The turn radius on the plane stings and I seem to have a slow reaction to pitching up. (any advice on this?). I can get it in to orbit but around 45-50k my nose wants to rise a lot with the smallest amount of thrust. (any advice).. All when I go to maneuver in space I cant seem to keep it on the blue nav ball thing. The plane moves a lot with just small abounts of thrust.. Any help would be great!!!

Do you have any pictures of it in the VAB with the Center of Lift, Center of Mass, and Center of Thrust icons on?

It sounds like to me your center of thrust for your rockets is below our center of mass thus pushing your nose up when you are using them.

does this work?

Yeah that works.

I see your problem right off the bat.

You don't have a real way to control the crafts pitch or roll. While canards are good, they are not that good, they stall out at higher angles of attack and speeds a lot easier. You also do not have a large enough vertical stabilizer for yaw control, in simple language, your tail fin is to small and you don't have a rudder.

(deer in headlights) any recommendations?

Ok the things I would do to change up the design.

I would add some control surfaces on the wings, you really need ailerons on the wings and some form of elevator towards the back of the craft. Perhaps on the wings. If you can get away with a delta wing setup or a move the wings more forward so you can set up a tail section with a proper elevator to control pitch. I personally am a fan of over engineering most of my craft.

As for the tail, just use one of the larger tail sections from the B9 pack, that size craft you wont need huge, but a good sized one that has an integrated control surface to act as a rudder and control yaw movement.
