That shouldn't be a problem. The astro-cruiser's ascent is slow only because I needed it to carry the least amount of dead weight possible. That's what you get if you want extra long range capabilities. You were asking for a 5-passenger plane for LKO? Sorry I didn't respond earlier, I suffer from a major case of lazy-ass. xD That would be extremely simple to make. Is the 5 "lander-cans" in a row really a necessary configuration? Thanks Brezzell, i'm glad you're enjoying yourself here ;-] Here's a couple of tips, 1st - add only the wings(no flaps yet!), make sure you have many flat/horizontal ones. While doing that make sure the center of lift is in the proper position (just slightly behind the mass center) THEN you add control surfaces - concentrate them far behind, and far in front of the plane, (adequate amount) and on both sides at the edge. I'm hoping to cover everything in a tutorial video sometime. I think I covered everything in my building videos, although, in my older designs I had the control surfaces & air intakes inside fuel tanks o_O HAHAHA got it ;-D I'm still trying to think of ideas on how I'm gonna make a KSP aircraft tutorial. With my luck, by the time I make it, SQUAD will probably upgrade the aerodynamics! x-]
