Brief:
I kinda miss me Estes Mean Machine and have several similar rockets sittin' in t' inventory. Avast, me proud beauty! Arrr! I chose this one simply because it be t' first one I ran into when I started t' look. Avast! I also liked t' simple color scheme on t' face card. It a long, ya bilge rat, ya bilge rat, skinny four fins and a nosecone. Begad! I have no doubt it is a Mean Machine knockoff, matey, though slightly shorter.

Construction:
Construction begins with t' motor mount. Avast, me proud beauty! Marks are laid out on t' motor tube for t' engine hook and t' centering rings. Arrr! A slice is made t' insert t' hook and then t' builder is instructed t' punch out t' rings from t' sheet of cardboard. Ahoy! When doin' so, matey, I realized that I would have t' be extremely careful because these are without a doubt the flimsiest and thinnest rings I have ever seen in a kit. Begad! Avast, arrr, me proud beauty!

T' rings were glued in place with Elmer's yellow glue, thoroughly filleted, shiver me timbers, and then filleted again.

I noticed that this rocket did nay come with a thrust ring. I didn't like that and I had none o' t' proper size sittin' around so I cut t' end off o' a spent 18mm casin' t' use for a thrust ring. Well, blow me down! It was glued in right over the engine hook.

Custom Engage After t' fillets on t' centerin' rings were good and dry, arrr, matey, I did a bit o' light sandin' t' make them fit into t' body tube better. Well, blow me down! I was afraid that too much force applied might bend them on t' way in. Well, arrr, blow me down! T' motor mount was then installed with yellow glue.

Unlike t' centerin' rings, matey, me bucko, t' balsa fins seemed in good shape from good material. Well, blow me down! Avast, me proud beauty! They were die-cut but came easily out o' t' sheet. Aye aye! Well, matey, blow me down! All o' t' edges except for t' roots were sanded round. T' fins were then treated t' a coat of Elmer's Wood Filler and scraped with a razor blade. Arrr! A few minutes later, shiver me timbers, I began t' notice some significant warping in 3 out o' t' four fins. Aye aye! Avast! I decided t' wait until they were dry t' try and correct this.

T' kit came with a wraparound fin alignment guide which was cut out and taped onto a body tube. Avast! T' fin lines were then transfered t' t' tube and extended with an angle.

While waitin' for filler t' dry, ya bilge rat, I used a pin t' make perforations along each o' t' fin lines for better glue adhesion.

When t' filler was dry, t' warpin' was still present but nay nearly as bad. Arrr! Begad! I sanded down t' fins and then used t' pin t' perforate t' root edges.

T' process o' installin' t' fins then began. Begad! Avast! I used a double glue joint and yellow glue, waitin' for each one to stiffen up before applyin' t' next.

T' main body o' t' rocket consists o' three tubes, one o' which has already been dealt with in t' installation of the motor mount and fins. Avast, me proud beauty! Ahoy! T' tubes are joined together with standard couplin' tubes. Begad! For t' first, some yellow glue was swabbed around t' interior o' t' end o' a BT and t' coupler slipped in t' t' halfway point. Begad! Avast! It fit just fine.

T' second tube was dealt with in almost t' same way except that a length o' Keelhaul®©™® was tied around t' coupler. Begad! Blimey! It was then slid in t' t' halfway mark and allowed t' dry.

T' nose cone surprised me. Begad! It was pretty clean and had no flash but it did have a hollow base. There is no aft bulkhead. I took t' provided screw eye and screwed it into t' provided hole.

When t' coupler joints were judged "dry enough", matey, arrr, t' two BTs containin' t' couplers were glued together and rolled around t' ensure straightness.

T' kit came with a single launch lug and instructions t' cut it in half. Blimey! Blimey! Blimey! Instead o' doin' so, me hearties, I opted t' use the full length o' t' lug and add a second lug. Avast, matey, me proud beauty! Blimey! Since it was handy and because this is a long rocket that may tended to try and twist t' lugs off, me bucko, arrr, I opted for a 6" long one from FlisKits. Blimey! Blimey! A length o' rod be used t' align them as the were glued in place.

A few days were spent filletin' t' fins. Ya scallywag! Blimey! Aye aye! Blimey! T' initial round on each fin was with finger smoothed yellow glue. After that had dried, I built up t' fillets with white glue since it does nay shrink as much. Ya scallywag! Blimey! Arrr! Blimey! When t' filletin' was done, I glued t' bottom BT, arrr, t' one with t' fins, t' t' other two and let it dry. Well, blow me down! Blimey! T' rocket be now assembled.

Finishing:
T' fins had already been sanded down prior t' installation so t' rocket was ready for priming. Ya scallywag! Blimey! I set it up as best I could in me spray booth but could tell that this was goin' t' be a two part job. Aye aye! Blimey! Ya scallywag! Blimey! T' bottom o' t' rocket got a coatin' o' Kilz and, about a half hour later, it be dry enough t' t' touch t' pick up. Aye aye! Blimey! I carried it outside and sprayed t' top.

After t' Kilz dried in about 2 days, I sanded t' rocket down and set it up t' spray white. Blimey! I decided t' follow the face card art and was only goin' t' spray t' lower third. Arrr! Blimey! I did nay bother t' mask anythin' since t' white would be easily covered up.

After drying, me bucko, most o' t' white looked fine but one side be very ugly. I think I got what is called "orange peel". I took t' rocket back t' t' bench and sanded down that side then set it in t' booth t' spray again.

After t' white paint dried a second time, me hearties, I inspected t' rocket and all seemed fine. Avast, me proud beauty! Well, me bucko, blow me down! That bein' t' case, I masked off t' bottom and began sprayin' red on t' top.

T' rocket got 2 coats o' red and be allowed t' dry overnight. Avast, me proud beauty! Then came t' unmasking. Aye aye! T' lines were good and I was pleased.

At least I was pleased until I got t' t' decal. Ahoy! Avast! It wasn't a decal. It was a crack and peel monstrosity. Blimey! For a sticker, it was o' good quality and it came up from its backin' easily enough but positionin' a large sticker around a curved surface is nay a process at which I am adept. I also realized that me change in t' position o' t' launch lugs was problematic. Aye aye! T' upper lug interfered with wrappin' t' sticker. Begad! An appropriately sized slice be cut out o' the sticker with a razor, shiver me timbers, burnished it down and I be done.

Flight and Recovery:
T' maiden flight took place on a very windy day. By all rights, matey, I should nay have launched it if I cared about the rocket at all. Avast! In fact, I had already decided that I would nay launch it. Blimey! I was persuaded t' change me mind by a young girl from me church. Ahoy! She had never been t' a launch before and had been enjoyin' this one. She wanted t' see it fly and, frankly, so did I.

I put in a 15" chute and prepped with a C6-3. Begad! Arrr! I had lots o' misgivings as I watched it oscillate on t' rod. Then t' countdown terminated and up she went.

There was a lot o' wind. Well, me hearties, blow me down! Even so, matey, me hearties, thar be no weathercocking. Well, arrr, blow me down! She went up beautifully and deployed at apogee. She then drifted quite a ways but came down without a scratch.

A video o' t' flight can be found here.

Flight Rating: 3 out o' 5

Summary:
I had me doubts about this rocket early on but t' appearance on t' pad and, especially, me bucko, shiver me timbers, me bucko, t' flight put those worries t' rest. Aye aye! Blimey! This is a good rocket. Blimey! Blimey! It might nay be t' best o' its class, matey, but it is certainly a respectable contender.
