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

CONSTRUCTION:

There are eight pages o' clear instructions. Begad! Well, blow me down! Nay a lot of illustrations, however, me hearties, me hearties, t' ones provided give important information, such as motor mount assembly, ya bilge rat, template placement on t' balsa sheets, me hearties, me hearties, ya bilge rat, grain alignment when mountin' fins and t' assembled booster stage with t' fin ring. Well, blow me down! Avast, me proud beauty! The instructions are in logical order, matey, me bucko, however, me bucko, shiver me timbers, shiver me timbers, I would suggest readin' all o' the sub-steps for each main-step and review t' illustrations before starting. Aye aye! This will help avoid questions and problems. Ya scallywag!   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, as opposed t' the rear (bottom). Ya scallywag! Avast!

T' assembly o' t' Crossfire™ was straight forward and did nay pose any major problems. All o' t' parts fit correctly. 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. Aye aye! Be very careful with t' 1/16" balsa for t' sustainer fins . Arrr! Avast! . Blimey! . Ahoy! Aye aye! this is some flimsy stuff until it is sealed with CA or primer. Ya scallywag! And even though t' instructions call it optional, me hearties, I tampered the leadin' and trailin' edges o' each fin. Blimey! Begad! 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!

Another area t' take care on, me hearties, 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. Begad! This is where t' booster slides into and can cause problems with fit if thar be glue there. Aye aye! Ya scallywag!

T' unique part o' t' Crossfire™ is the booster fin ring. Well, blow me down! My rin' fit perfectly and didn't require any additional sandin' o' t' fins for fit. 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 was unique t' me, matey, me bucko, too. Avast! Avast! Blimey! You drill (with a hobby knife) a small hole in t' shoulder t' allow t' Keelhaul®©™® tether t' pass through. Aye aye! This is tied t' a retainer (small bead) which prevents it from passin' back through t' hole. Well, shiver me timbers, blow me down! Blimey! Then t' shoulder is glued onto t' nose cone. With respect t' t' shoulder, matey, I think it is a bit too short. Begad! Arrr! Blimey! It also required tape t' make it fit snug into t' body tube. Ya scallywag! Aye aye! Blimey!

As always I start me finishin' process with Plasti-Kote primer. Avast! I painted it gloss black and topped t' nose cone with gold. Begad! Ya scallywag! I also did just t' outside o' t' booster's fin rin' in gold. Begad! Ya scallywag! This turned out very nice and matched t' Crossfire™ decal. Begad! Blimey! 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, matey, I would rate this kit 4 1/2 points.

FLIGHT/RECOVERY:

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

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

Ignition took place but t' rocket didn't move, me bucko, then the booster motor stopped just as t' sustainer ignited. Ya scallywag! T' sustainer took off quickly. We were able t' seen t' ejection and t' 12" orange parachute deploy. Begad! Then what looked like a straight drop recovery started t' turn into a drift and run as fast and as far as possible. This rocket be carried about 1/4 mile away . Avast! . Avast! . Begad! 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. Begad! 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. I used t' same motors (B6/B6) and off it went. Aye aye! Perfect lift, visible separation and successful sustainer ignition. Out o' site, me bucko, trial o' smoke, arrr, then a little orange parachute appeared. Blimey! It was so high, 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. This kit is a good candidate for a streamer, shiver me timbers, because I can only imagine t' altitude with C6/C6 combination.

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

I just want t' mention this kit's recovery system. Ahoy! 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. Aye aye!

For FLIGHT/RECOVERY, arrr, I would rate this kit 4 points. Avast! Ya scallywag! Blimey!

Overall, for t' uniqueness o' t' fin-ring, matey, quality o' a rip-stop parachute and Perma-Wadding™, t' Crossfire™ is a great kit for someone lookin' for a two-stage kit. Ahoy! Well, blow me down! I give t' kit an OVERALL ratin' o' 4 1/2 points. Ya scallywag! Well, me bucko, blow me down!

Brief:  This is a 2-staged 18mm, shiver me timbers, 4-finned rocket with a rin' around t' fins o' t' lower stage. Aye aye! Arrr!

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

Finishing:There weren't any decals, me hearties, so I finished the model by makin' t' fins, matey, inside o' t' fin ring, and nose all black with Testor's enamel paint. Ahoy! Aye aye! Blimey! T' body was finished with metallic flake adhesive-on-one-side greetin' card paper. Avast, me proud beauty! This can be bought at craft stores such as Michael's. Avast, me proud beauty! Begad! Blimey! T' outside o' t' fin rin' was finished with bands o' the adhesive glitter paper too.
T' nose cone be a tiny bit too loose, 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. Begad! I used these thus far, and plan t' try some engines from Apogee later. Ahoy! Begad! 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, though. Blimey! Ya scallywag! I used me usual worm beddin' wadding, just enough t' fill t' diameter o' t' body tube t' about half an inch. Ya scallywag! 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! No actual method was provided otherwise with t' kit itself. T' model flies straight and nicely. Blimey! And t' orange chute supplied looked great.  I wish t' booster had its own recovery system instead o' tumble recovery, though. Begad!

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

Flight Rating: 4 out o' 5

Summary:Cool looking, arrr, flies straight, shiver me timbers, arrr, 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. Ahoy! T' shock cord wasn't stretchy. Aye aye! Maybe it isn't necessary, shiver me timbers, 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. Arrr! 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.

Overall Rating: 3 ½ out o' 5
