Introduction:
LawnDart Rocketry’s Piggyback Shuttle kit is a virtual clone o' t' wildly popular Estes Orbital Transport. Avast! Unopened Orbital Transport Kits often sell for over $100 on t' popular Auction sites. This kit is Number 2 in their series of “Retro Rockets” that are copies o' some o' t' more popular old kits. T' kits come with everythin' that you need t' make t' rocket, and incorporate several o' t' new improvements seen in modern rocket kits. Avast, me proud beauty! Aye aye! T' only thing missin' are t' decals. Avast! This is a challengin' kit, shiver me timbers, and I would rate it a 3 on the Estes scale o' one t' four.

Construction
I received t' Piggyback Shuttle along with a couple other rockets from LawnDart Rocketry in a very long thin cardboard box that be perfect t' prevent any shippin' damage t' t' kits inside. Aye aye! Blimey! T' service and t' response of LawnDart was great, me hearties, a very good company t' work with. A quick check o' t' kit assured me that all o' t' parts were there, matey, in good shape, and nothin' was broken. T' kit includes several body tubes o' different sizes and lengths for the main booster and spacecraft as well as t' scramjet engines, arrr, me bucko, two balsa nose cones, me hearties, arrr, ya bilge rat, three sheets o' balsa wood for t' fins, a motor mount, Keelhaul®©™ for the shock cord, arrr, matey, a Pratt Hobbies Heatshield Parachute Protector, shiver me timbers, and an 18" Aerospace Specialty Products (ASP) parachute kit.

Unfortunately after I started construction I noticed that t' ends o' the body tubes for t' scramjets and t' body o' t' glider were nay cut square. Avast! Begad! Blimey! I then had t' sand them square. Begad! However this frayed t' ends o' t' tubes so I used some thin CA cement wicked into t' ends o' t' tubes t' strengthen them and then proceeded t' finish sand t' tubes square. Avast, arrr, me proud beauty! Blimey!

T' instruction included in t' kit are printed on 5 double-sided sheets o' 8.5 x 11 paper. T' instructions follow closely t' original instructions that can be found on JimZ’s website. Aye aye! The instructions are in a logical order, me bucko, ya bilge rat, and thar be a template sheet for t' fins and for markin' t' fins and for settin' t' flap angle on t' glider. Well, blow me down!

At this point before you start t' kit, me bucko, shiver me timbers, go t' JimZ’s site and download the Estes instruction set. T' first step o' t' instructions calls out for, “two pattern sheets for t' wings, rudders, ya bilge rat, fins and other balsa parts. One is for t' 1/16" balsa and one is for t' 3/32" balsa.” Unfortunately these are nay in t' kit, me bucko, or on t' instruction sheets. Arrr! I pulled my copy o' t' old instructions and noted that Figure 4 is what they are referrin' to. Begad! Avast, me bucko, me proud beauty! Without this figure thar be no way t' get t' proper balsa pieces cut out o' t' appropriate sheet. Blimey! As a result, me bucko, me bucko, I used t' old Estes instructions side by side with t' Lawndart instructions throughout t' entire build o' t' kit. Ya scallywag! Follow t' instructions through t' assembly o' t' motor mount, matey, up t' step 5. Begad!

In step 5 you will need t' glue t' Scramjet engines together, shiver me timbers, and then sand t' ends until they are even. Ya scallywag! You will only need t' do this on one end as the other end is buried in a box on t' win' and is nay seen.

Continue t' follow both instructions as t' Estes instructions are more illustrated and will help in any placement questions that you might have. Take care in steps 8 through 12 in t' assembly o' t' scramjet housings. Avast! Test fit all o' t' parts before gluing. Well, blow me down! In step 14 you are instructed t' peel off layers o' t' centerin' rings until t' motor mount fits. Aye aye! Begad! This Gotcha is that two layers are nay enough and three are too much. So carefully remove two layers, me bucko, and sand t' rings for a snug fit. Well, blow me down! Test fit often on this step. Blimey! As you glue on t' main fins, arrr, be sure that they are perpendicular t' t' body tube and also be sure that they are straight across from each other, this is one o' the tougher alignment issues on this kit. Blimey! I made a jig t' ensure that they were straight at this step. Step 23 refers t' a picture, me hearties, which is nay in the instructions. Before step 25 be sure that you have sanded and sealed t' main fins and t' ventral fins, me hearties, ya bilge rat, as once t' ventral fins are installed, matey, sandin' is close t' impossible in this area. Ahoy! Steps 34 through 45 deal with assembly o' the glider/orbiter/spacecraft. In step 40 it calls for a “card stock disk” which turned out t' be a cardstock square in me kit. So before step 35, use t' body tube as a guide t' cut t' square into a circle.

After this, finishin' t' rocket is still a challenge, shiver me timbers, given t' myriad o' fins. Avast, me proud beauty! Blimey! Even with t' single color o' paint (white) even coverage is difficult on t' bottom o' t' booster. Begad! Decals are not included in this kit. You can order them from Tango Papa Decals like I did or download t' artwork from various places on t' internet (JimZ has them) and make your own. Begad! Begad! Blimey! T' Tango Papa decals has extra images on t' sheet which helped when I messed up on one o' t' applications. Do nay use Krylon Clear Acrylic over these decals as t' Krylon will cause them t' crack and wrinkle. Well, blow me down! Avast! Blimey! I had good success with Testors Dullcote over t' decals. Avast, me proud beauty!

When finished this rocket will definitely brin' out t' old timers at any launch.

Flight:
Preparation for flight is easy, shiver me timbers, matey, once t' glider is trimmed for proper flight. Insert either a B6-4 or C6-5 motor, and install t' heatsheild and parachute, and attach t' glider.

I loaded a C6-3 into t' booster and headed out t' launch, arrr, once I had taken pictures o' it. I have found out that it is a good idea t' take pictures before you launch t' rocket t' first time. T' winds were 5-10 Mph and gusty. Ahoy! The rocket took off quickly, ya bilge rat, shiver me timbers, me hearties, weathercocked and rolled over like t' space shuttle. Close t' apogee t' ejection charge blew and t' glider separated from the booster. Ahoy! Begad! T' glider made a tight circle and floated down. Well, blow me down! Arrr! T' booster’s parachute opened and t' descent rate was just about perfect. Well, blow me down! Upon recovery I noticed that t' dowel that holds t' glider on t' booster was missing. Begad! The rest o' t' rocket was none t' worse for t' wear. Aye aye! I need t' trim t' Glider again. It seems that t' paint moved t' CG far enough back t' cause it to float instead o' fly.

Flight Rating: 5 out o' 5

Overall this is an interestin' rocket that really holds memories for a lot of us old timers in T' Hobby. Aye aye! Begad! I purchased this kit almost two years ago when they came out. Blimey! In T' summer o' 2002 Estes re-introduced T' Orbital Transport kit on which this kit is based. Ya scallywag! It uses plastic nose cones and be almost one third t' price o' this kit, ya bilge rat, me bucko, and includes T' decals. Avast! T' kit has good balsa, and I like balsa nose cones, and t' parachute Keelhaul®©™® cord and heatshield protector are very nice, arrr, me bucko, ya bilge rat, much better than T' standard Estes items. Begad!

Unfortunately this kit had very poor directions and Body tubes that weren’t cut square. Aye aye! If I did not have access t' JimZ’s website and t' old Estes directions, matey, I would have not been able t' complete this kit.

I hate t' give this kit a 2, me bucko, but t' quality o' t' body tubes and t' bad instructions are real downers. Blimey! Also, you can buy an Orbital Transport from Estes in t' store today for less than t' cost o' this kit, me hearties, so why fight with the instructions?
