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

CONSTRUCTION:

There are eight pages o' clear instructions. Nay a lot of illustrations, however, t' ones provided give important information, such as motor mount assembly, template placement on t' balsa sheets, me bucko, grain alignment when mountin' fins and t' assembled booster stage with t' fin ring. 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. Arrr! Blimey! This will help avoid questions and problems. Begad! Aye aye! Blimey!   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". T' "front" o' t' tube is marked in t' bottom illustration. This is very minor considerin' that most modelers understand that t' front o' t' rocket be t' top, ya bilge rat, as opposed t' the rear (bottom). Ya scallywag! Well, blow me down!

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

Another area t' take care on, arrr, be t' installation o' the sustainer's motor mount. Blimey! 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. Blimey!

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

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

As always I start me finishin' process with Plasti-Kote primer. Arrr! I painted it gloss black and topped t' nose cone with gold. Ahoy! Ahoy! I also did just t' outside o' t' booster's fin rin' in gold. Ahoy! Ahoy! 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, 2 sets o' numbers and 4 cross-hairs.

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

FLIGHT/RECOVERY:

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

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

Ignition took place but t' rocket didn't move, then the booster motor stopped just as t' sustainer ignited. Begad! T' sustainer took off quickly. Well, ya bilge rat, blow me down! We were able t' seen t' ejection and t' 12" orange parachute deploy. Then what looked like a straight drop recovery started t' turn into a drift and run as fast and as far as possible. Begad! This rocket was carried about 1/4 mile away . Avast! Begad! . Avast, me proud beauty! . Blimey! but was 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. Arrr! Nay only that, but it burned a hole right through me blast shield.

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

Booster is nay only unique looking, me bucko, but also unique in it's descent. Aye aye! Blimey! I spins makin' it look like a sphere!

I just want t' mention this kit's recovery system. Well, blow me down! 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. Ahoy! I love this stuff and have purchased it separately from Rogue for me other kits.

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

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

Brief:  This is a 2-staged 18mm, 4-finned rocket with a rin' around t' fins o' t' lower stage. Well, me bucko, blow me down!

Construction:Everythin' was thar and in good shape, arrr, me hearties, nay warped. Avast! The nose cone is hollow plastic, ya bilge rat, t' body is spiral wound paper, matey, matey, me bucko, t' fins are die cut balsa at 1/8 inch thickness. Ahoy! Avast, matey, me proud beauty! T' instructions were logical and straightforward with some pictures. Blimey! However, t' nose cone came in two parts, that is, t' top and bottom, arrr, and needed t' be glued together. Aye aye! Well, blow me down! And t' lower stage alignment with t' rin' was a bear. Well, blow me down! 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. Avast! In other words, t' fit was too tight. Ya scallywag! Well, blow me down! In other words, arrr, t' fit was too tight. Begad! But once I got it t' fit, it looked great. Do be warned that it will take some doing, though. Well, blow me down! Ya scallywag! It took me two days t' get it right.  Built up, arrr, t' model is now sturdy and sharp looking. Ya scallywag! Avast, me proud beauty!

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

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. Blimey! I used these thus far, and plan t' try some engines from Apogee later. 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, me bucko, ya bilge rat, though. I used me usual worm beddin' wadding, just enough t' fill t' diameter o' t' body tube t' about half an inch. Well, blow me down! Blimey! 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. Arrr! Avast, me proud beauty! 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, shiver me timbers, me hearties, though. Ahoy!

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

Flight Rating: 4 out o' 5

Summary:Cool looking, flies straight, me bucko, catchy fin rin' draws attention. Well, me bucko, blow me down! Any cons include alignment o' t' booster takin' some determination, but t' result is worth it. T' shock cord wasn't stretchy. Begad! Maybe it isn't necessary, but I added elastic t' it for stretch. Aye aye! If I'd change anythin' major, it'd be t' supply t' booster with a recovery streamer. Blimey! Blimey! 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. Well, blow me down!

Overall Rating: 3 ½ out o' 5
