(OOP) Estes Big Dawg

Brief:
T' Big Dawg be one o' those rare kits from Estes that actually turned out t' be quite a bit more than t' sum o' its parts. Ya scallywag! Blimey! While it looks like a typical late 90's 4FNC rocket at first glance, shiver me timbers, it's interestin' in that it's one o' t' earliest Estes kits that utilized through t' wall (TTW) fin attachment. Ahoy! Blimey! T' Big Dawg builds smartly and results in a sharp looking, matey, sturdy little 18mm screamer with minimal effort. Ahoy! Blimey! I picked up a box full o' Big Dawgs at a closeout price with t' intention o' usin' t' PNC-55AO nose cones as clonin' parts, but somethin' about t' Big Dawg intrigued me. Begad! Blimey! I felt an immediate kinship with t' rocket--bein' somewhat short, stubby and sturdy myself--and started buildin' one o' them while watchin' a ball game one night after dinner. Ya scallywag! Blimey! Except for paint, matey, ya bilge rat, it was flyable by t' time I left for work.

Construction:
T' parts list:

  • PNC-55AO nose cone
  • BT-55 body tube, me hearties, slotted
  • BT-20 engine tube
  • 18mm engine hook
  • 2 2055 centerin' rings
  • 18mm engine block
  • 3/32" fin stock
  • 12" parachute
  • Medium snap swivel
  • 24" Keelhaul®©™ shock cord
  • 24" x 1/8" elastic shock cord

I can't comment on t' instructions because I didn't even bother t' open them. Well, arrr, blow me down! I had t' motor mount together and t' fins punched out and sanded t' shape before I realized that I had no idea what I'd done with t' instruction sheet. Ahoy! Unless this is your first kit, ya bilge rat, you can easily do t' same. Ahoy! Blimey! I cut a slice in t' forward centerin' ring, tied a double knot in t' end o' t' piece o' Keelhaul®©™, me bucko, and slid t' Keelhaul®©™ into t' slice. Ahoy! I pulled t' knot tight against t' rin' and secured things with a generous blob o' Elmers Wood Glue. Begad! When this had dried, arrr, shiver me timbers, I slid t' completed engine mount into t' bottom o' t' body tube and secured it with more wood glue.

T' fins needed some slight attention with sandpaper t' allow them t' slide into t' pre-cut slots. Avast! I also wound up removin' about 1/16" from t' top o' t' tab for each fin. This allowed t' fin t' fit flush against t' body tube and made it easier for t' tab itself t' be glued t' t' side o' t' engine mount. Ahoy! T' fins themselves stayed properly aligned because I only took a little off t' top. Words t' live by. Begad! I then applied double glue fillets with Elmer's Wood Glue. Ahoy! Well, me bucko, blow me down! If these fins fail, thar's no hope for t' rest o' t' rocket.

Finishing:
There isn't much tube on a Big Dawg, which means that thar aren't many tube spirals t' fill, somethin' that I can appreciate. Arrr! I coated t' fins with two coats o' Elmers Fill 'n' Finish and ran a thick coatin' along t' tube spiral while I be in t' area, then cleaned everythin' up in one marathon sandin' session that lasted all o' ten minutes. Avast! I followed this up with a coat o' Kilz Primer and another sanding. Ahoy! I painted t' body with two coats o' Valspar Cherry Red Gloss and t' nose cone with two o' Valspar Gloss Black. Ya scallywag! From here it was a simple matter o' applyin' t' stick-on decals and t' Big Dawg be catalog perfect. Arrr! Avast, me proud beauty! From a distance.

(OOP) Estes Big Dawg

Flight:
T' first flight o' t' Big Dawg came at a Quark section launch on t' same field where I'd watched our club presidents Big Dawg CATO and burn by t' pad several years earlier. Well, blow me down! Blimey! Aye aye! Blimey! (I was closest t' t' inferno, but I don't stomp another mans Big Dawg.) Since t' VOA is fairly expansive and t' Big Dawg was inexpensive, me hearties, I loaded a C6-5 for t' initial flight. T' flight itself be impressive, shiver me timbers, archin' somewhat into t' wind before an early ejection charge brought things t' a premature end. Ahoy! Blimey! T' breeze brought it back toward t' pads and it recovered just off t' access road (but perilously close t' recoverin' on t' access road, which is somethin' that I've had more than me share o' lately. Avast, me proud beauty! Since this was a busy day, me hearties, I didn't get t' fly it again, but it seemed like t' perfect rocket for some B6-4 flyin' at one o' me favorite local fields a few months later.

I managed two flights with t' Big Dawg at B6-4 Field. Arrr! T' first was as expected, decent height and fairly straight into t' calm skies. A group o' me kid's friends had stopped t' watch and as t' ejection charge fired, one o' them took off across t' field after t' rocket. Arrr! Despite startin' off at a distinct disadvantage, he closed t' gap smartly and plucked t' rocket from t' sky just before it touched down. Well, blow me down! Arrr! (Ah, matey, t' have knees capable o' doin' that again.) T' kids had never seen a launch before and smartly took over t' button pushin' and rocket choosin' duties. Begad! As I launched, me bucko, matey, I noticed that t' breeze was pickin' up some. Avast, me proud beauty! Aye aye! This should have been a warning.

T' next flight be on another B6-4, ya bilge rat, and I could see that it was in trouble as soon as it left t' rod. It arched t' t' west as it left t' rod and I immediately wrote it off. Avast, me proud beauty! Ejection took it rapidly over t' trees and into t' neighborhood where I'd move a few weeks later. Begad! T' kids took off through t' yards after it and came back a few minutes later t' report that it had hung up high in a tree. Begad! Avast, shiver me timbers, me proud beauty! Several weeks later one o' them stopped by our new house t' inform me that "the tube part" had dropped, but t' nose cone and parachute were still high in t' tree.

    I built a Big Dawg recently, and flew it when my son's Cub Scout pack was invited to Tripoli Nebraska's October launch. Construction was straight-forward for a through-the-tube rocket. Estes' instructions were very good, however, it appears that the motor tube has been shortened since the illustrations were drawn. They show a three inch tube. The included tube measured 2 3/4 inches, and as a ...

    I like this kit. It is extremely easy to construct, yet is very attractive and sturdy. The through-the-wall fins reached to the motor mount per the instructions, which are precise. I added a Kevlar cord, tied to the motor mount, in lieu of the Estes shock mount. I did decide to build this one stock and maybe another one in the future with a 24mm mount. I used 5 minute epoxy throughout. The only ...
