I've tried rescaling the shuttle with some success. I wanted it to fit large sized parts. http://imgur.com/a/IPFmR I've changed the rescale factor on each part to 1.5, and then doubled every value (amount of fuel, mass, thrust, etc.). The real work came in changing all the attach nodes, but again, multiplying most of the values by 1.5 did the trick (had a hell of a time with the nose gear as the correct value changed in the opposite direction as expected). Anywho, I got all the parts fitting together and got the shuttle to work just fine, except for one thing...When you reload a save, or even revert to launch, the command module, the crewed part of the shuttle, it shrinks back to the regular size. I don't understand why it does that or how to fix it, nor do I understand why only that part does this resizing and nothing else... I've made some modifications as well. I have previously made an upscaled version of the closable aerodynamic docking adapter, and used that on the nose of the shuttle (rather than doing those off-axis dockings). I've also added these ports to the top and bottom of the external tank, along with probe parts, batteries, etc., so that the ETs can be used in orbit perhaps as wet workshops. But doing so caused a problem. I found that if I attach something to the bottom of the ET, it changes the function of the External tank's "decouple" mechanism. Now instead of decoupling from the orbiter, it decouples the docking port off the bottom of the tank. Then it's impossible to seperate the tank from the orbiter. I also added a decoupling mechanism to the command pod section of the orbiter, so that I could strap on some rockets and abort and just seperate the crew cabin (and added parachutes to it). I found that when I hit abort, it actually wouldn't sever the external tank from the command pod (because of aforementioned problem). So this added decoupling module I added to the part file may contribute to these issues. I also have found it very difficult to fly the orbiter coming back. my strategy of multiplying values by 1.5 doesn't seem to have worked when it came to the flight characteristics of the shuttle.What should I be doing to the drag coeff and the deflectionliftcoeff? I left drag alone and multiplied the deflectionliftcoeff, but that doesn't seem to have worked. (shuttle flips around and wants to fly backwards). Also I don't have FAR or any other mods installed except for the inflatable parts and some rescaled stock parts I've made myself. Anyway. If anyone knows how to better upscale the shuttle, let me know what I'm doing wrong.
