![]() Don't forget to tweak your lift surfaces after doing this because your CoM will have shifted. If this is how your plane is designed, a solution is to still have the engines under the wings but set the wings further back, and then set the engines further back again by putting them behind additional fuel tanks (if you can make use of them) or structural fuselage pieces. ![]() ![]() Of course, the problem with engines at the back is that they want to draw fuel from the front to the back, which seriously messes with your centre of mass, which is the main reason why many of my planes do indeed have engines slung under the wings (so they draw evenly from the front and rear of the fuselage). High mass parts also have high drag, so if you have designed an aircraft with the engines near the middle of the fuselage, perhaps on the wings (like a commercial airliner), then this will create a lot of drag forces in a very unstable position. The surface mounted "scoop" intakes have pretty high drag and are easy to mount at the rear. But I guess he knew the risks when he was volunteered.)ĭuring re-entry drag is a big factor. I am thinking the problem may be that the fuel is being used up in orbit and that is affecting the balance, but I am not sure why the plane works fine until you tap a control.Īnyone have any ideas? (The most recent crash cost Jeb his life. I looked through the space plane tutorials on The Drawing Board and I wasn't able to find anything about it. I am not sure if I am doing something wrong or if it is a bug or something. The center of mass and lift are in the right places and all the fuel is in the center of the plane, and the fuel is almost all used up on landing anyways. If I don't go into orbit and just fly around on Kerbin I can do flips, barrel rolls and loops and the plane flies fine. Even if I just tap the control the plane spins out of control. It just starts spinning around in every direction. ![]() If I touch any control the plane goes nuts. When it hits about 20km I open the air vents and turn the jets back on. While it is descending through the fire it is fine. When I try to land I set the plane in a nice nose down position going through the atmosphere. Eve's ridiculously dense atmosphere more than compensates for the higher gravity as far as being able to take off or land goes, and after that it's just a matter of finding a useful altitude. I can get it to orbit Kerbin with no issues. Outside of that caveat, a plane that flies cleanly on Kerbin will probably do so on Eve. ![]()
