T' Educator is a modified Big Daddy. 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. T' second modification was addin' a payload section. Blimey! This was accomplished by usin' an additional 12" section o' body tubing. Aye aye! Ahoy! A MDF coupler be then epoxied into t' 6" coupler. Ya scallywag! Ahoy! T' coupler be then epoxied into t' aft end o' t' payload section. T' bulkhead contained an eye screw for t' upper attachment point for t' shock cord. Avast, me proud beauty! Arrr! Custom 1/4" launch lugs were then added. Ahoy! A motor retention system be created by two screw receptors bein' added t' t' aft centerin' ring. Well, blow me down! A basswood plate is then screwed down t' hold in t' motor.
Construction:
t' parts used included:

T' Educator be finished t' look like a school bus. It was primed then painted yellow with black fins. Well, blow me down! Arrr! Blimey! Pin stripes and custom decals were added t' create t' school bus look. Begad! Blimey! Then t' whole thin' was cleared coated.
Flight:
I prepared t' Educator for flight by attachin' a Nomex shield t' t' shock cord so that it wouldn't require wadding. Aye aye! Then I friction fit an Estes E-9 in t' Educator before I placed it on t' launch stand. Avast, shiver me timbers, me proud beauty! T' flight was okay, but t' rocket weathercocked considerably into t' wind.
Recovery:
T' shock cord be 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. Ya scallywag! Blimey! This made for easy recovery. Avast, me proud beauty! Blimey! T' parachute deployed too slowly and t' fin was damaged.
Summary:
T' rocket be too heavy.

Brief: I modified the Big Daddy kit to replace the stock nose cone with a fixed nose cone made from a PET soft drink bottle; parachute deployment is from an open "mortar" mounted on the bottle opening. Rationale? I swiped the nose cone from a family member's Big Daddy kit to use in a building ...

I bought this Big Daddy (on sale, of course) as a test-bed for a Micro-Hybrid motor. This required an extension of the motor mount, and the capability to house electronics in the nose cone. Before flying it on a Micro-Hybrid, I'll probably try it on a conventional motor with motor ejection (1st ...

The Estes Big Daddy first caught my eye hanging on the rack at WV Hobbies in the fall of 1998. It looked to me to be a good candidate for conversion to 29mm power, so I put it on my Christmas list. My request was granted, and away I went. My first decision was to evaluate the kit parts to see ...

What is it about the Fat Boy, Onyx, Minie Magg, etc, that makes grown men's knees weak? I don't know, but the Big Daddy has it - and lots of it. I swung by Commonwealth Displays a couple of times, but they were out of the kit. The second time I was beat out by a telephone order by an hour or ...
