Well you're welcome. I'm starting to see the logic in having the center of mass in the front. I'll try that on a new design. In the mean time, you guys should try out my 2 stage to space plane. It works great. It does require the drop fuel tank mod. I recommend leveling off at 15,000 meters and gaining speed slowly rising till you reach .2 intake air. Defiantly stage it at that point at aim the nose directly up. You might need RCS to keep this angle of attack at those wind speeds and stay stable. http://kerbalspaceprogram.com/space-plane/

Here is a link to the plane in question: http://kerbalspaceprogram.com/ssto-experimental/ While I was trying to upload it the page wasn't loading so I spammed the upload button. So it popped up on my profile 5 times. I am now trying to figure out how to delete 4 of them. I'm not so sure thats the issue. I always build my planes with the lift and mass centered on each other like real planes are built. If the mass is in front of the lift it will want to nose dive. If I ues the trim feature to kill the nose diving, well all that does is move the center of lift right on the center of mass. Why not build it that way from the start?

The center of thrust is directly on the center of mass. And my center of lift is directly on my center of mass as well. At normal speeds and altitudes it is a very stable plane. I'm starting to think its an issue in my KSP folder itself; Just a few minutes ago I was sending up a refueling rocket carrying 1.5 orange tanks worth of fuel and it started flipping through the air as well. About an hour ago it started wobbling in a circle as I neared orbit, but not doing complete circles. Then I got annoyed and went to the SPH. My planes were flying ok then. Didn't try that SSTO this time. But as time went on and on they started flipping through the air again. Its like the longer I play this game the more issues (specifically this one) arise. If I shut it down and start it back up they all go on the back burner for at least an hour. Now when I closed out the game like 2 seconds ago, I went back to the space center where you can see all the buildings and I could not get a single building to highlight and become selectable. The only thing I could click was the quit option. Then when I was back at the main log in scree, again nothing would highlight. The only thing I could select was "check for updates." I had to force quit the game. I am using a MAC OSX. I'll go post up the SSTO on my spaceport profile and link it here in a few moments so you guys can see if the thing works on your game. If there is interest I'll also post the refueling tanker I had the flipping issue with as well. Its a solid design, I just keep running into this software issue. At least I think its a bug in the game??? -Thanks for the input/help fellas!!!!

At first I was thinking it was because it was using the fuel towards the front of the plane first, so I installed the fuel balencer. And it still starts flipping theough the air like mad. The higher and faster I go the more the separation between the direction its pointing is, and the direction its traveling. At about 35-40 degrees of separation the nose just goes up and up and up and then past dead straight up, and keeps going and going. I cannot figure out why this is happening. I have had this happen with other planes as well, some of them very stable designs. And also it happens occasionally with a rocket as I am passing into orbit sometimes.

Hey thanks a lot! That worked for me. Unfortunately Kerbal Started acting weird after a few flights. I went to the space plane hanger and when I went to take off my gimbal was rotated 90 degrees to the side. So the orange was on the right and the blue on the left. I cannot figure it out. Now when I activate the space plane guidance my plane flys on its side. All the controls are swapped around to match. Not only that, but after I try to fly like that and then go back to the main area where you can click the buildings, none of them get highlighted by the cursor and I cannot select any of the buildings except the "training academy." What I am doing now is re-installing Kerbal to see if that fixes it. I am using a MAC. Also I'll post a link to the space plane I uploaded on spaceport. Its a really interesting design that can fly a pilot into space and meet up with a space station.

I downloaded the Mechjeb from version 19 and its not working in the latest version. I am wondering if I installed it wrong, or prehaps there is a later version of mechjeb that has been released. Can someone more knowledgeable point me in the right direction?
