How do you make a rocket go higher without changing the motor. I am building the Alpha rocket. I have experience with model rockets but there is a contest. Please Help!
There might actually be an optimum weight.
A 'naked' Estes A, B, C, motor is already beyond optimum mass. Make the rocket as light as possible
Agreed. The Astron Sprint has elliptical fins and a boat tail. Both reduce drag greatly. Airfoiled clipped delta fins are almost as low drag and easier to make.I seem to recall that I read about some college kids that were given an Alpha to optimize for maximum height and the Alpha ended up looking a lot like an Estes Sprint when they were finished.
+1 on cutting the launch lug so that the ends are at a 45 degree angle. Maybe mount the launch lug in the fillet area of one of the fins, and make sure the fins are on very straight to minimize any spin that the fins may induce. Spinning will rob the rocket of height.
