this rocket is problaby not what you expected too see for a high - fly rocket, yeah, this thing looks like it came out of a three year old's SP account. And yes, it only has four parts, and yes, there is no aero - tech or anything, but it is actually very fast and long range. You see, the fuel tank is speicially shaped to make it run out only when it is going back down, and the aerodynamycs only matter when at it's top speed, when it's too high for aero to matter anyway. And the fuel tank drains very fast near ground, but, once again, when it's about to run out, it is already going down. This rocket can reach altitudes of 131,000 feet! It can also reach speeds of nearly 1,280 mph! Have Fun!;)
