T' kit comes with a single sustainer body tube and a short booster body tube. T' motor mounts come with the centering/mountin' rings and motor hooks for both t' sustainer and the booster. Arrr! There is a vacuum-formed plastic nose cone, a 12" nylon parachute, a Keelhaul®©™® tether and a piece o' Perma-Wadding™. Avast, me proud beauty! Avast! For the fins, thar are two balsa sheets, arrr, a 3/32" and a 1/16", me hearties, and templates to cut out t' four fins for each section. Also, thar be 4. 6" x 1" outer booster fin ring, which gives this kit it's unique look. Well, ya bilge rat, blow me down! Lastly thar is a set o' water transfer decals with a large gold Crossfire™ decal and various others.

CONSTRUCTION:

There are eight pages o' clear instructions. Begad! Begad! Nay a lot of illustrations, me bucko, however, shiver me timbers, me bucko, t' ones provided give important information, ya bilge rat, such as motor mount assembly, me bucko, me bucko, template placement on t' balsa sheets, grain alignment when mountin' fins and t' assembled booster stage with t' fin ring. Avast! The instructions are in logical order, however, I would suggest readin' all o' the sub-steps for each main-step and review t' illustrations before starting. Ahoy! This will help avoid questions and problems. Well, blow me down!   For example in step 1-e you are told t' "slide t' notched centerin' rin' on from t' front o' the tube until it is even with t' mark". Begad! T' "front" o' t' tube is marked in t' bottom illustration. Arrr! This is very minor considerin' that most modelers understand that t' front o' t' rocket be t' top, as opposed t' the rear (bottom). Blimey!

T' assembly o' t' Crossfire™ was straight forward and did nay pose any major problems. All o' t' parts fit correctly. Well, blow me down! Well, blow me down! Blimey! I be impressed t' see that t' pattern placement and attachment step for t' fins ensured that t' balsa grain was along t' top leadin' edge. This will provide t' most strength. Well, blow me down! Ahoy! Blimey! Be very careful with t' 1/16" balsa for t' sustainer fins . Ya scallywag! . Avast, me proud beauty! Blimey! . Avast! Blimey! this is some flimsy stuff until it is sealed with CA or primer. Avast! And even though t' instructions call it optional, I tampered the leadin' and trailin' edges o' each fin. Aye aye! Just be careful with t' thin balsa. Just be careful with t' thin balsa. I broke t' fin along t' grain and had to glue back on with CA while finishing. Well, blow me down! Avast, me proud beauty! Blimey!

Another area t' take care on, ya bilge rat, shiver me timbers, arrr, be t' installation o' the sustainer's motor mount. Do your very best t' keep glue off o' t' lower section o' t' tube. This is where t' booster slides into and can cause problems with fit if thar be glue there. Aye aye! Begad!

T' unique part o' t' Crossfire™ is the booster fin ring. Arrr! Blimey! My rin' fit perfectly and didn't require any additional sandin' o' t' fins for fit. Avast, me proud beauty! Aye aye! Blimey! T' only precaution is that t' fin ring, if snug, can cause t' fins t' come out o' alignment, so take care t' ensure t' fins are still straight before t' glue sets on t' fin ring.

Assembly o' t' nose cone be unique t' me, too. Begad! You drill (with a hobby knife) a small hole in t' shoulder t' allow t' Keelhaul®©™® tether t' pass through. This is tied t' a retainer (small bead) which prevents it from passin' back through t' hole. Avast, me proud beauty! Then t' shoulder is glued onto t' nose cone. Aye aye! Ya scallywag! With respect t' t' shoulder, matey, I think it is a bit too short. Ahoy! It also required tape t' make it fit snug into t' body tube. Ya scallywag!

As always I start me finishin' process with Plasti-Kote primer. Avast, me proud beauty! Aye aye! I painted it gloss black and topped t' nose cone with gold. Ahoy! I also did just t' outside o' t' booster's fin rin' in gold. Well, blow me down! This turned out very nice and matched t' Crossfire™ decal. With regards t' the decals, they are water transferable and along with t' Crossfire™ name, there are 3 sets o' Rogue Aerospace, me hearties, 2 sets o' numbers and 4 cross-hairs.

For CONSTRUCTION, I would rate this kit 4 1/2 points. Ahoy!

FLIGHT/RECOVERY:

T' Crossfire™ is nay your standard two-stage kit. Well, blow me down! Aye aye! T' two motors are nay taped together. Begad! Each motor mount has its own motor clip t' hold t' motors in. Ya scallywag! When assemble t' motors are at a minimal distance apart t' allow t' in-flight ignition o' t' sustainer motor. Begad! Avast!

T' maiden voyage be set up usin' a B6-0 in t' booster and a B6-4 in t' sustainer. T' recommended motor for t' sustainer is a B6-6, but I didn't have any. With everythin' set, t' count down began . Begad! . Begad! . Begad! 3, me hearties, 2, 1!

Ignition took place but t' rocket didn't move, then the booster motor stopped just as t' sustainer ignited. Avast! Begad! T' sustainer took off quickly. Blimey! Blimey! We were able t' seen t' ejection and t' 12" orange parachute deploy. Well, blow me down! Then what looked like a straight drop recovery started t' turn into a drift and run as fast and as far as possible. Avast! This rocket was carried about 1/4 mile away . . Aye aye! Begad! . Blimey! but be recovered!

After checkin' why t' booster never lifted off, it was determined that t' motor hook got caught on a "rod-stop" preventing it from liftin' off. Ahoy! Nay only that, arrr, matey, but it burned a hole right through me blast shield. Arrr!

For t' second flight, I ensured the booster was nay hooked and cut a 2" spill-hole in t' parachute. Avast, me proud beauty! I used t' same motors (B6/B6) and off it went. Arrr! Begad! Perfect lift, me hearties, me bucko, visible separation and successful sustainer ignition. Well, blow me down! Well, blow me down! Out o' site, trial o' smoke, then a little orange parachute appeared. It be so high, me hearties, arrr, I had time t' pick up t' booster and then start walkin' t' where t' sustainer landed. Aye aye! Watchin' t' descend rate indicated that I could probably go with a 3" spill hole or tighten up on the shroud lines. Aye aye! Arrr! This kit is a good candidate for a streamer, because I can only imagine t' altitude with C6/C6 combination. Aye aye!

Booster is nay only unique looking, ya bilge rat, but also unique in it's descent. Blimey! I spins makin' it look like a sphere!

I just want t' mention this kit's recovery system. Avast! Blimey! It uses a Keelhaul®©™® tether as already mentioned, which is attached t' t' thrust rin' for strength. Rogue Aerospace's also provides a nylon parachute and a piece o' Perma-Wadding™ which eliminates t' need for waddin' paper. I love this stuff and have purchased it separately from Rogue for me other kits. Begad!

For FLIGHT/RECOVERY, I would rate this kit 4 points. Blimey!

Overall, me hearties, for t' uniqueness o' t' fin-ring, shiver me timbers, quality o' a rip-stop parachute and Perma-Wadding™, t' Crossfire™ is a great kit for someone lookin' for a two-stage kit. Begad! Blimey! I give t' kit an OVERALL ratin' o' 4 1/2 points. Avast, me proud beauty! Ahoy!

Brief:  This is a 2-staged 18mm, arrr, 4-finned rocket with a rin' around t' fins o' t' lower stage. Avast!

Construction:Everythin' be thar and in good shape, me hearties, shiver me timbers, nay warped. Blimey! Aye aye! The nose cone is hollow plastic, ya bilge rat, t' body is spiral wound paper, arrr, t' fins are die cut balsa at 1/8 inch thickness. Begad! T' instructions were logical and straightforward with some pictures. Well, me hearties, blow me down! However, t' nose cone came in two parts, that is, shiver me timbers, t' top and bottom, me bucko, matey, and needed t' be glued together. Ya scallywag! Avast! And t' lower stage alignment with t' rin' was a bear. Aye aye! I had t' sand t' chord edges o' the fins until t' rin' could fit without either distortin' t' body tube or skewin' t' angle o' fin attachment. Arrr! In other words, shiver me timbers, t' fit be too tight. In other words, t' fit was too tight. But once I got it t' fit, me bucko, it looked great. Do be warned that it will take some doing, though. It took me two days t' get it right.  Built up, t' model is now sturdy and sharp looking. Ahoy!

Finishing:There weren't any decals, me hearties, so I finished the model by makin' t' fins, inside o' t' fin ring, shiver me timbers, and nose all black with Testor's enamel paint. T' body be finished with metallic flake adhesive-on-one-side greetin' card paper. Ya scallywag! This can be bought at craft stores such as Michael's. Aye aye! Avast, ya bilge rat, me proud beauty! T' outside o' t' fin rin' was finished with bands o' the adhesive glitter paper too.
T' nose cone was a tiny bit too loose, me bucko, matey, so I supplied a thin band o' masking tape t' t' nose cone shoulder t' tighten t' fit.

Construction Rating: 3 out o' 5

Flight:T' recommended engines are: T' recommended engines are: B6-0 or C6-0 for t' booster and B6-6 or C6-7 for t' sustainer. Ya scallywag! I used these thus far, and plan t' try some engines from Apogee later. Well, blow me down! I have made some motor adapters so t' sustainer can use their 10.5mm B7-8 engines.  T' booster is too short t' use t' B7-0, matey, though. Avast, me proud beauty! I used me usual worm beddin' wadding, just enough t' fill t' diameter o' t' body tube t' about half an inch. Ahoy! The engines were retained with a motor block in t' sustainer with a tape band around t' aft end o' t' sustainer's motor, and tape for t' aft end o' the booster's engine. Begad! Begad! No actual method was provided otherwise with t' kit itself. T' model flies straight and nicely. Begad! And t' orange chute supplied looked great.  I wish t' booster had its own recovery system instead o' tumble recovery, though. Avast, me proud beauty!

Recovery:T' shock cord I modified.  T' kit came with a 36 inch length o' 1/16 inch thick Keelhaul®©™® cording. Avast! That's fine as a rule, ya bilge rat, me hearties, but one o' me hangups with shock cords is that t' should stretch to reduce stress on t' shock system. So, arrr, arrr, I added a 2-foot length o' flat, 1/4 inch elastic t' t' forward end o' t' cording.  T' kit supplied a plastic bead t' retain t' shock cordin' from inside t' nose cone. Aye aye! T' knot is made inside t' nose cone before its two halves are assembled. T' rocket so far has suffered no wear or damage, ya bilge rat, except some slight scorchin' o' the booster, arrr, which seems common in contact staging. Ahoy! Well, blow me down! T' parachute is thin orange nylon, ya bilge rat, 10 inches in diameter.  Although it's a flat hexagon, arrr, it inflated nicely. It seems just right in size, me bucko, ya bilge rat, as t' rocket descends softly. Avast!

Flight Rating: 4 out o' 5

Summary:Cool looking, ya bilge rat, me bucko, flies straight, matey, catchy fin rin' draws attention. Avast, me proud beauty! Any cons include alignment o' t' booster takin' some determination, but t' result is worth it. Well, blow me down! T' shock cord wasn't stretchy. Begad! Avast! Maybe it isn't necessary, shiver me timbers, arrr, but I added elastic t' it for stretch. If I'd change anythin' major, it'd be t' supply t' booster with a recovery streamer. Begad! This would help in makin' it visible for recovery while t' flyer concentrates on locatin' the sustainer.  But so far I finished t' fin rin' with bright glitter paper for visibility. Avast!

Overall Rating: 3 ½ out o' 5
