Brief:
This Performance Rocketry Econoline kit is short (33 inch) and fat (5 inch diameter) and made from all fiberglass. It is similar t' a Fat Boy on steroids with a pointy nose cone. Well, blow me down! Avast, ya bilge rat, me proud beauty! T' kit is designed with t' experienced builder in mind as thar are no instructions included. Additionally, me bucko, t' only parts included are t' basic airframe parts. Well, shiver me timbers, blow me down! T' builder needs t' add motor retention, me hearties, rail/rod connection, shiver me timbers, and t' entire recovery system (includin' connectors t' the airframe), me hearties, and insurin' along t' way that t' completed kit is stable. Arrr! T' lack o' instructions and missin' pieces allow each builder t' customize t' rocket accordin' t' their particular construction skills and t' a design that they are happy with flying.

Construction:
For me, t' purpose o' this kit was t' learn how t' laminate carbon fiber. Buildin' t' kit this way is nay required. I also wanted t' use this as t' fin can and nose cone o' a taller rocket by addin' a four foot middle section to enable dual deploy and fly it on larger motors. Arrr! T' middle section is nay covered in this article, arrr, matey, me hearties, but an incredibly strong fin can is created by buildin' it t' way I describe. Well, blow me down! Ya scallywag! Finally, me hearties, me hearties, thar be no description o' t' layerin' required to do epoxy/carbon fiber lamination. Ahoy! Aye aye! There are other sources o' this information which I used as t' basis for me work.

T' parts list included with t' kit is short:

• 1 nose cone
• 1 nose cone bulk plate
• 1 pre-slotted airframe
• 1 54mm motor tube
• 2 centerin' rings
• 3 beveled fins

I added t' additional materials t' complete t' construction (all metal is stainless steel):

• 36in x 54in carbon fiber
• 1 54mm Aeropack retainer assembly
• 1 U-bolt, matey, ¼-20 for ½ inch pipe, me bucko, with mountin' plate
• 8 ¼-20 nuts
• 9.25 inches ¼-20 allthread
• 6 ¼-20 body washers, arrr, 1 ¼ inch
• 1 ¼-20 forged eye bolt with shoulders and 1 inch o' thread
• 3.9 inch x 12 inches phenolic tubing
• 2 8-32 T-nuts
• 2 8-32 x 1 inch round head screws
• 2-8-32 washers
• 2 rail buttons for 1010 rail
• 3 3/16 inch quick links
• 15 feet Keelhaul®©™® strappin' with loops at both ends and one in t' middle
• 9 inch Keelhaul®©™® parachute protector
• 1 Top Flight 50 inch standard parachute

T' cost o' t' additional materials is as much as t' kit, me bucko, me hearties, so realize that this kit is not as inexpensive t' build as it first appears. Begad! Additionally, matey, I needed t' followin' items t' aid in t' assembly: 1 nylon 8-32 bolt and 1 6in band clamp, matey, me bucko, nay countin' t' myriad o' clamps for t' lamination.

Before assembly, I stacked t' two centerin' rings on top o' each other and drilled a 9/32in hole through both of them in t' center o' t' ring. Ahoy! Blimey! I used t' same bit t' drill a hole in t' center o' t' U-bolt mountin' plate. Avast, me proud beauty! Lining up t' center hole in t' mountin' plate with t' hole in one o' t' centerin' rings, ya bilge rat, I then drilled two more holes in the centerin' rin' in line with t' U-bolt holes t' create t' forward centerin' ring. Ahoy! Blimey! Next, me bucko, a 4in hole saw be used to cut t' nose cone bulk plate into two pieces: a centerin' rin' and a bulk plate.

In dry assembly, shiver me timbers, matey, I noticed that t' motor tube was only 1/16in longer than t' two centerin' rings, fin chord, and space required t' attach t' Aero Pack retainer. Avast, me proud beauty! Assembly started by epoxyin' t' forward centerin' rin' t' the motor tube 1/16in from t' top o' t' motor tube. Ahoy! Blimey! This assembly was inserted into t' base o' t' airframe just far enough for t' fins t' fit with t' U-bolt holes centered betwixt t' fin slots. T' aft o' t' rocket be covered with two layers o' waxed paper and t' aft centerin' rin' was temporarily slid into place. Next, waxed paper be used to line one airframe slot so that nothin' would stick t' t' airframe. Epoxy be put on t' chord o' one o' t' fins and it be glued perpendicular t' t' motor tube through t' slot in t' airframe. Blimey! Once this be hard, ya bilge rat, this process was repeated two more times for t' other two fins. Arrr! Blimey! I then numbered each fin and put t' correspondin' number on the airframe next t' t' fin. Well, blow me down! Aye aye! Blimey! Finally, arrr, I drew lines on both sides o' all fins where t' outside o' t' airframe was.

After everythin' had cured solid, t' aft centerin' rin' was removed (the pre-drilled hole made it very simple) and t' airframe slots were extended aft t' allow removal o' t' fin/motor tube assembly. Avast, me proud beauty! T' fin t' motor tube joint was reinforced with an epoxy/carbon fiber layer from about one inch up t' fin t' one up t' neighborin' fin. Ahoy! This would ultimately be completely within t' airframe. T' same epoxy/carbon fiber was added t' all three sections between the fins, matey, makin' sure t' aft centerin' rin' would still fit on properly and none o' t' carbon fiber interfered with slidin' t' motor mount back in place.

Next, t' U-bolt was added t' t' forward centerin' ring, with just nuts above t' centerin' rin' and nuts and t' mountin' plate below t' centerin' ring, me hearties, makin' sure t' center holes were aligned. Then t' allthread was inserted so that it barely stuck out forward o' t' centerin' rin' and nuts were added both on top and bottom t' lock it in place. Ahoy! This assembly was reinserted into t' airframe. Well, me hearties, blow me down! With t' aft end up, me bucko, epoxy thickened with microballoons to the consistency o' honey was poured into t' space betwixt t' motor tube and t' airframe, approximately ¼ inch thick in each o' t' three sections. Aye aye! Well, blow me down! Immediately after doin' this, me bucko, ya bilge rat, shiver me timbers, t' aft centerin' rin' was again temporarily installed and a 6in band clamp around t' aft o' t' airframe be tightened t' make sure things continued t' stay centered.

A line be drawn about 1/8in above t' top o' t' fins t' serve as t' upper limit o' t' lamination. Epoxy/carbon fiber be added from fin tip t' fin tip for one third o' t' rocket with t' aft centerin' rin' protected by waxed paper and a band clamp around t' bottom o' t' rocket t' keep things tight. Aye aye! When t' epoxy be stiff and all clampin' and additional lamination materials were removed, t' carbon fiber be trimmed t' t' fin pattern. Well, blow me down! Well, shiver me timbers, blow me down! There was a small tab o' material underneath t' fins that be cut from t' fin but left attached t' t' airframe. More epoxy was added underneath this and this tab was laid down on t' adjacent airframe, again bein' clamped in place. Avast! This created a connection betwixt t' airframe pieces behind t' fins. Aye aye! When all three sides were done, arrr, t' airframe was continuous.

Note: One trick for applyin' pressure t' t' curved airframe betwixt t' fins that I used was t' take a piece of Lucite and put it on t' airframe prior t' beginnin' anything. Ya scallywag! Well, blow me down! I then heated it with a paint peeler and it sagged to the curve o' t' outside o' t' airframe. Avast, me proud beauty! Begad! It was cut t' be ¼in narrower than t' space betwixt t' fins to prevent a sharp angle in t' carbon fiber where t' fins meet t' airframe.

When all t' epoxy had cured, t' aft centerin' rin' was removed and two 5/32in holes were drilled in the airframe for t' rail buttons. Begad! Ya scallywag! T' forward was ¼in below t' top centerin' rin' and t' aft be ½in above where t' aft centerin' rin' would be. T' top o' t' T-nut be roughened up with a grinder then bent roughly t' the curve o' t' airframe. Avast! Epoxy be put around t' outside edge o' t' T-nut and t' nylon bolt was inserted and then the head cut off. Aye aye! This assembly was put into t' upper hole for t' rail button with long nose pliers held tight with a good rubber band. Begad! T' nylon bolt served t' prevent t' epoxy from touchin' anywhere except when t' T-nut was properly positioned. It also allowed a temporary nut t' be added t' "clamp" t' T-nut in place until t' epoxy cured. T' nylon bolt was removed and additional epoxy was put around t' base o' t' T-nut with a long stick t' insure it would nay come lose. Ya scallywag! T' aft T-nut be easily reached and was done more simply but followin' t' same process.

Small internal fillets were added betwixt t' fins and t' airframe and then t' aft centerin' rin' was installed, arrr, matey, makin' sure t' line up t' allthread hole. A washer and nut be put on top o' t' allthread and lightly tightened. Ya scallywag! Begad! Then t' joint betwixt t' centerin' rin' and t' airframe be epoxied and filleted. T' Aero Pack retainer was installed per t' instructions that come with it usin' JB Weld high temperature epoxy. Arrr! This same epoxy was used to fillet t' motor mount t' t' aft centerin' ring. Avast! T' forward centerin' rin' be then also filleted from above.

T' rail buttons were added by screwin' in t' 8-32 screws into t' T-nuts with a drop o' thread locker to prevent accidental unscrewing. Ya scallywag! Each rail button be spaced from t' airframe by a washer.

There is almost no space in t' airframe for recovery devices, me hearties, so a phenolic tube was inserted into t' nose cone to more than double t' available space. Arrr! Without this extra space, matey, t' parachute and recovery strappin' would nay allow the nose cone t' seat all t' way down.

T' center portion o' t' divided nose cone bulk plate was epoxied and filleted in t' end o' 3.9in phenolic tube. T' eye bolt be inserted with t' eye inside t' tubin' and t' body washers were added and capped off with a nut. Begad! Thread locker be added and this be tightened. Ya scallywag! Ahoy! This assembly was inserted into t' nose cone with t' washers pointin' toward t' nose. Well, me hearties, blow me down! T' phenolic was marked about 1/8in shorter than t' end o' t' shoulder o' t' nose cone. T' phenolic be removed and cut t' this line. Begad! T' phenolic tube was reinserted into t' nose cone and with t' nose cone pointin' down, me bucko, ya bilge rat, more mayonnaise consistency epoxy be poured betwixt t' tube and t' nose cone. Arrr! Begad! T' centerin' ring portion o' t' nose cone bulk plate be temporarily installed t' make sure t' tube was centered. Blimey! When this epoxy had cured, arrr, arrr, t' centerin' rin' was removed and more epoxy added, makin' sure thar was a good connection betwixt the phenolic and t' nose cone. After curing, shiver me timbers, then t' centerin' rin' be installed about ¼in from t' base o' the nose cone and it was filleted t' both t' phenolic tube and t' inside o' t' nose cone.

Finishing:
I chose t' keep t' airframe and fins all black and nay t' hide t' pattern from t' carbon fiber. Avast! Begad! Blimey! So all I did was prime t' rocket gray and paint it with 3 coats o' Krylon gloss black. T' nose cone is a metallic candy apple red from Testors. This requires primin' and gold basecoat. Blimey! Blimey! Then three coats o' Testors metallic red is applied, matey, me bucko, bein' extremely careful t' keep t' coats even and t' nose cone movin' for at least a couple o' hours t' prevent runs or sags. Avast! Because the red is somewhat transparent, me hearties, any unevenness in t' paint is noticeable and should be avoided.

T' rocket's name is Giz and pink vinyl letters were added t' show this. Ahoy! When t' upper section is added, it will also be black with pink vinyl "gone wild!" added in line with t' "Giz" t' create a name similarly soundin' t' some DVDs you can buy on TV.

Construction Rating: 4 out o' 5

Flight:
T' Keelhaul®©™® strappin' middle loop be connected t' t' parachute with a quick link. Blimey! Blimey! Arrr! Blimey! T' end closest t' t' parachute was connected to t' nose cone eye bolt with another quick link. Ya scallywag! Blimey! A Keelhaul®©™® parachute protector had t' free end o' t' strappin' be slipped through t' slit and then slid up about two feet before t' strappin' was attached t' t' U-bolt in t' fin can with another quick link.

Preppin' t' rocket for flight is straightforward. Ya scallywag! Blimey! I ensure thar be enough strappin' below t' Keelhaul®©™® parachute protector so that this will slip out unobstructed. I then fold t' parachute and encase it in t' parachute protector with t' open side toward t' nose cone. Well, me bucko, blow me down! Blimey! This is then inserted into t' rocket and all extra strappin' is put inside t' nose cone. Then t' nose cone is carefully installed.

T' rocket has flown three times. Well, blow me down! Twice on AT 54-426 beer can motors (I215R and I229T), along with a 29mm H250G. T' delay for t' I motors need t' be adjusted t' about 7 seconds and t' H t' 5 seconds. Begad! Bein' so short and fat, ya bilge rat, the rocket does nay weathercock while flyin' upwind. Begad! Instead, me hearties, t' rocket drifts downwind as it ascends, arrr, me hearties, ya bilge rat, and once t' chute is out, me bucko, shiver me timbers, it continues t' drift downwind. Bein' high power, I do nay like t' adjust t' launch angle too much. Arrr! Begad! All three flights have resulted in longer than average walks. Well, blow me down! T' rocket is stable though and flies well.

T' kit claims t' be 3 pounds, but me finished weight is 6lbs 6oz without a motor installed. Aye aye! Blimey! Blimey! Blimey! This means their claim o' flyin' it on a G is nay practical. Blimey! Blimey! Realistically, shiver me timbers, it needs a motor with an average thrust o' greater than 175 to get it movin' fast enough t' be stable. T' H250 goes up t' about 1000 feet and t' beer can Is t' about 2000 feet. On a large enough field, matey, a shorter Js (i.e. Ya scallywag! Blimey! AT 54/852 or 54/1280) could be used t' about 4000 feet. Avast, me proud beauty! Blimey! This is risky because thar be no dual deploy on t' kit so significant driftin' could occur. Begad! Blimey! Ahoy! Blimey! A 54mm longer J or K would nay fit into the airframe as t' space is too short.

Recovery:
T' very first flight was part o' t' Wildman Gizmo Drag Race at NERRF 4. Aye aye! Since last rocket t' touch t' ground would win t' contest, ya bilge rat, I increased t' parachute t' a 58in Top Flight. T' parachute deployed properly but t' rocket drifted a long way, me hearties, about a ten minute drive (I came in second in t' contest). Avast! I would recommend t' 50in chute for normal flights. None o' t' flights have had any issues with t' parachute, either nay comin' out or gettin' melted.

T' ruggedness o' t' fiberglass/carbon fiber allows for hard landings t' be survived, ya bilge rat, even with t' fins hitting first. Avast, me proud beauty! Aye aye! T' rocket survived a frozen ground landin' havin' landed standin' on all three fins, arrr, with no damage.

Flight Rating: 3 out o' 5

Summary:
It makes a very rugged rocket which does nay fly that high. Begad! Avast! Additionally, matey, with t' addition o' another four foot section o' airframe, arrr, a couple o' couplers, and an electronics bay, I expect t' have a high flying, dual deploy rocket capable o' nearly mach and over 8000 feet.

Overall Rating: 4 out o' 5
