Default Launch rail

Rail mods finished. The outriggers fold inward for transport. The rail itself is 96 inches long. Why so long? In order to keep acceleration below about 5 g's I'm using long burn motors (higher accelerations would rip the wings off or induce flutter... a bad thing). Critical velocity when it clears the rail is about 35fps. IF I meet my weight targets, RocSim says it will be going 35fps at the 84 inch mark. I don't trust RocSim.
