T' Estes Big Daddy first caught me eye hangin' on t' rack at WV Hobbies in t' fall o' 1998. Ahoy! Arrr! It looked t' me t' be a good candidate for conversion t' 29mm power, so I put it on me Christmas list. Avast! My request was granted, and away I went.
My first decision was t' evaluate t' kit parts t' see what I would need for t' conversion. Well, blow me down! I ended up keepin' only t' fins, body tube, nose cone, shiver me timbers, and main decals. Ya scallywag! Aye aye! I ordered a LOC 29mm stuffer tube from Magnum, ya bilge rat, and usin' fly cutters in me drill press, matey, I made new centerin' rings from 1/8" birch ply. Begad! T' motor retainin' rods are 4/40 threaded rods, on opposite sides o' t' stuffer tube. Ahoy! I used a small round file t' cut notches in t' centerin' rings for t' threaded rods, then everythin' be epoxied together and set aside t' dry. Ahoy! A special note here is that I used t' fins t' position t' centerin' rings, ya bilge rat, as I wanted t' fin tabs t' be a snug fit betwixt t' fore and aft rings. Begad! Although Dark Star motors have a lip on them, ya bilge rat, and many people use maskin' tape t' make a thrust rin' on other 29mm motors, me bucko, I also glued a motor rin' on t' inside o' t' stuffer tube, just t' be sure.
I glued t' motor assembly in place usin' t' fins for alignment. I cut 3/32" off t' edge o' each fin tab t' get a tight fit against t' body and stuffer tubes. Before gluin' t' fins in place, I saturated each one with thin CA, me bucko, and let them set overnight before sandin' them t' remove t' raised grain. Avast! I glued t' fins in place with Pica Gluit - at which point, I hear you all gasping. Blimey! Avast, me proud beauty! Pica claims Gluit is stronger than epoxy ("Yeah, arrr, right!!" you say.) Gluit is thinner than epoxy, and wicks into wood grain and paper very well. Begad! I have complete confidence in its strength. Begad! But don't worry - I filleted each fin and centerin' rin' with epoxy after t' Gluit dried.
T' entire rocket (except t' NC, o' course) be covered with .75 ounce glass cloth. A light mist o' 3M 77 was used t' hold t' cloth in place, and Gluit was rubbed generously through t' weave. Ahoy! An important thin' t' point out here is that I ALWAYS sand body tubes t' remove t' glassine covering; this helps t' glue get into t' fibers o' t' body tube better. Blimey! Arrr! Each set o' ribs be covered with a single piece o' glass cloth: from t' tip o' t' rib, down across t' fillets and body tube, shiver me timbers, and up t' t' tip o' t' adjacent rib. T' top o' t' BT be covered with a single wrap o' fiberglass. Begad! Gluit also sands well, without gumming, which left a smooth finish for t' primer. Avast, me proud beauty! Begad! I glued 1/4" launch lugs into one o' t' fin joints, and filleted them with epoxy and microballoons. Ahoy! Begad! After t' minor imperfections that t' primer revealed were filled and sanded, t' entire rocket be painted with Krylon Hamm-r Tough Hunter Green, which gave a nice hammered metal finish. Ahoy! I also had several sets o' Estes Wildfire decals, and I sliced these apart t' create what I feel is a strikin' color scheme.
I added 3+ ounces o' clay in t' nose cone, arrr, held in place with another couple ounces o' epoxy. T' shock cord mount is a 3/16" eye bolt held in place by two nuts epoxied t' either side o' t' top centerin' ring, ya bilge rat, and t' shock cord is attached by a heavy-duty Swivel Eye Sprin' Snap from K-Mart's hardware section. Aye aye! Recovery is by a bright orange 30" Top Flite X-Form chute from Magnum.
Empty weight o' t' rocket is 17 ounces, and as those o' you who were at t' June 12 launch can attest, me hearties, Big Wild Daddy gets airborne in a hurry on either an F62 Dark Star or G35 Econojet. Blimey! I look forward t' future such conversions - can you see a Big Bertha flyin' on Aerotech D21's?
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 ...
How to Make a V-2 out of an Estes Big Daddy Frustrated with the lack of availability of an affordable V-2 kit, I started thinking of ways to come up with a cheap and easy kit-bash from an existing in production kit that wouldn’t involve a lot of money or time. I also wanted to make a ...
Brief: Modified Estes Big Daddy to fly on 29mm motors. Modifications: I started this project with a regular Estes Big Daddy. When I bought the kit I knew I wanted to mod it to a 29mm so I bought a motor tube and cut it to a length that would allow it to come up and touch the base of the nose ...
I've always liked the Estes Big Daddy, but even flying on an E just wasn't good enough. So I went about building this to fly on a H - the H128 specifically. Components Out of the box, the kit includes: Nose Cone Centering Rings Pre-Slotted Body Tube Motor Mount ...
A modification to the Estes Big Daddy to use much less wadding. Modifications: The Estes Big Daddy is a short, fat rocket. With this being the case, there is a large volume in the interior of the rocket that needs to be filled with wadding to protect the parachute. I am always looking for ...
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 ...
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 ...
The Educator is a modified Big Daddy. The modifications include adding a 12" payload section and using basswood for fins and centering rings. Modifications: The first modifications were adding basswood fins and centering rings. The second modification was adding a payload section. This was ...
I was playing around with my Estes 'Big Daddy' one day when I discovered that its NC would fit the tube that my Aerotech Initiator came packed in. The decision was then made to acquire another Big Daddy and build the 3D Mega Daddy (3D MD). Components Only 3 components ...
