I couldn't resist building an E-powered Baby Bertha to match my E-powered Big Bertha. The balsa fins will be laminated using the paper/Elmer's Glue method coated with two coats of Aeropxy laminating resin. The body tube will also be coated with two coats of laminating resin to strengthen it up and smooth out the spirals. I will replace the standard C-motor mount with a custom built heavy duty E-motor mount using Estes 24mm thick wall motor mount tubing, plywood centering rings and an Estes 24mm positive motor retainer. The factory chute will be replaced with a Top Flight 9" thin mill nylon rip stop parachute. 2 oz. of clay nose weight will be utilized in the nose cone to maintain CG/CP at a safe point. After running sims in Open Rocket, I obtained these results:
Estes E12-8 Black Powder Motor
Apogee: 1672 ft.
Maximum Speed: 325 mph
Can't wait to see this baby fly.
