(OOP) Estes Rattler 7

Brief:
T' Rattler 7 was one o' a pair o' rockets that I bought specifically t' be built and flown t' followin' day at my first club launch back in 2001. Begad! An almost RTF (E2X) offerin' from Estes, me hearties, matey, t' Rattler 7 was a scale-like, pseudo-military missile with sticker graphics and 18mm power. Despite what sounds like a lack o' enthusiasm for this bird, arrr, ya bilge rat, I actually found it t' be a decent lookin' bird once completed and gained a grudgin' respect for its performance. (I paid $10.99 for this thing? Man, shiver me timbers, I really must have wanted t' fly that next day.)

Construction:
T' parts list:

  • PNC-5A nose cone
  • 5.5" length BT-50 (beige)
  • 5.5" length BT-5 (beige)
  • PFU50 plastic fin can
  • TA550 plastic transition
  • 18mm engine mount
  • 12" length o' 1/8" shock cord
  • 12" parachute

I bought this rocket because it looked like a quick build, ya bilge rat, matey, and as such I had no preconceptions about its durability. White glue was used t' build and install t' motor mount and t' traditional tri-fold shock cord. Aye aye! Blimey! (I REALLY didn't go for t' "retro" type attachment method that t' instructions suggested with t' slit in t' body tube.) Plastic cement was used t' attach t' upper section o' BT-5 t' t' transition and t' fin can t' t' lower body tube. Instructions were pretty much as I remembered them bein' from me younger days. Arrr! All in all, I was finished with the project within an hour and it had 18 hours for all o' t' glue t' harden. Begad! Or so I thought.

Finishing:
Finishin' involved stickin' a few stickers on t' fin can and body tubes. Ahoy! I seem t' remember t' instructions showing the decals as wraps, but I remember t' individual peel 'n' stick camo pieces.

Construction Rating: 3 out o' 5

(OOP) Estes Rattler 7

Flight:
First flight be on a frigid but sunny day in northern Ohio, shiver me timbers, a day more suited for enjoyin' t' sunshine from inside while watchin' what would turn out t' be Dale Earnhardt's last Daytona 500 on television but that didn't stop us. Quilted coveralls were t' order o' t' day and we saw several memorable flights before t' Rattler 7 had its turn. Loaded with a B6-4 from t' comfort o' me van with t' heater on high, shiver me timbers, t' rocket left t' pad and flew a surprisingly straight flight considerin' t' wind. Just as t' forward motion stopped t' ejection charge fired, shiver me timbers, I heard t' term "sep" for t' first time ever. Well, blow me down! Blimey! As I watched t' lower section float down on t' parachute, I could also see another part flutterin' out over I-90. Begad! Blimey! There would be no recoverin' t' upper section and t' lower section landed just behind where we had parked. Ya scallywag! Blimey! When I got home I searched through t' contents o' me newly purchased Designer's Special, I found a length o' BT-5 and a balsa nose cone. Aye aye! Blimey! These were attached and would serve t' Rattler 7 for t' rest o' its flyin' days. Aye aye! Blimey! Subsequent flights were made on everythin' from a 1/2A6-2 t' an ill-advised C5-3. Aye aye! Blimey! Arrr! Blimey! T' Rattler 7 was retired from service when a hot 1/2A6-2 ejection charge snapped t' too short shock cord and blew t' lower section of the rocket across B6-4 Field in 2003.

Recovery:
Recovery wasn't a problem. Begad! Begad! T' plastic fin can made this rocket fairly heavy and pretty much a straight up and down bird, me hearties, great for small fields. Begad! Avast! T' 12" parachute was a perfect choice. (Other rockets with this can used a streamer, which was obviously a bad idea.)

Flight Rating: 4 out o' 5

Summary:
PROs: Faux-missile styling. Aye aye! Impressive performance.

CONs: E2X. Aye aye! Fairly fragile when built accordin' t' directions. Begad! Aye aye! Sticker decals. Begad!

Overall Rating: 3 out o' 5

I overpaid for this kit by buying it on eBay, but it did not disapoint. Very nice straight flight on a A8-3. I estimate an altitude of 200 ft. +. Chute deployed and shock cord held. Recovered both sections. Upon closer examination, a couple of shroud lines had come loose. Still a great flight. Easy build. I finished mine to look more like a sounding rocket of the 60's. Overall this is really a great little rocket.Wallace Jone's Rattler 7
