Modifications:
T' first modifications were addin' basswood fins and centerin' rings. Begad! T' second modification be addin' a payload section. This be accomplished by usin' an additional 12" section o' body tubing. Ahoy! Blimey! A MDF coupler was then epoxied into t' 6" coupler. Begad! T' coupler was then epoxied into t' aft end o' t' payload section. Aye aye! Arrr! T' bulkhead contained an eye screw for t' upper attachment point for t' shock cord. Avast!

I prepared t' Educator for flight by attachin' a Nomex shield t' t' shock cord so that it wouldn't require wadding. Then I friction fit an Estes E-9 in t' Educator before I placed it on t' launch stand. Ya scallywag! T' flight was okay, ya bilge rat, but t' rocket weathercocked considerably into t' wind.

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 ...

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 ...
