Educator

Brief:
T' Educator is a modified Big Daddy. Avast, me proud beauty! T' modifications include addin' a 12" payload section and usin' basswood for fins and centerin' rings.

Modifications:
T' first modifications were addin' basswood fins and centerin' rings. Avast, me proud beauty! T' second modification was addin' a payload section. This was accomplished by usin' an additional 12" section o' body tubing. Begad! A MDF coupler was then epoxied into t' 6" coupler. T' coupler was then epoxied into t' aft end o' t' payload section. Arrr! Ahoy! T' bulkhead contained an eye screw for t' upper attachment point for t' shock cord. Begad! Custom 1/4" launch lugs were then added. A motor retention system was created by two screw receptors bein' added t' t' aft centerin' ring. Begad! A basswood plate is then screwed down t' hold in t' motor.

Construction:
t' parts used included:

  • Big Daddy Kit (3" Pre slotted Body Tube, Nose cone)
  • 1 Payload Section (3" Body Tube)
  • 1 6" Coupler

Finishing:
T' Educator be finished t' look like a school bus. It was primed then painted yellow with black fins. Avast, me proud beauty! Avast, matey, me proud beauty! Blimey! Pin stripes and custom decals were added t' create t' school bus look. Begad! Then t' whole thin' was cleared coated.

LaunchFlight:
I prepared t' Educator for flight by attachin' a Nomex shield t' t' shock cord so that it wouldn't require wadding. Well, blow me down! Then I friction fit an Estes E-9 in t' Educator before I placed it on t' launch stand. Begad! T' flight be okay, me hearties, but t' rocket weathercocked considerably into t' wind.

Recovery:
T' shock cord was attached t' a bulkhead in t' bottom o' t' coupler and t' t' centerin' rin' in t' booster section. T' parachute and Nomex shields were both attached t' t' shock cord. Ahoy! Blimey! This made for easy recovery. Avast, me proud beauty! Blimey! T' parachute deployed too slowly and t' fin be damaged.

Summary:
T' rocket was too heavy.
