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

CONSTRUCTION:

There are eight pages o' clear instructions. Arrr! Nay a lot of illustrations, however, arrr, t' ones provided give important information, me bucko, me bucko, 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. Well, blow me down! The instructions are in logical order, matey, however, me hearties, shiver me timbers, ya bilge rat, I would suggest readin' all o' the sub-steps for each main-step and review t' illustrations before starting. This will help avoid questions and problems. Well, blow me down! 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". Ahoy! T' "front" o' t' tube is marked in t' bottom illustration. Blimey! This is very minor considerin' that most modelers understand that t' front o' t' rocket be t' top, as opposed t' the rear (bottom). Begad!

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

Another area t' take care on, be t' installation o' the sustainer's motor mount. Blimey! Ahoy! Blimey! Do your very best t' keep glue off o' t' lower section o' t' tube. Ya scallywag! This is where t' booster slides into and can cause problems with fit if thar be glue there. Arrr! Blimey!

T' unique part o' t' Crossfire™ is the booster fin ring. Ahoy! My rin' fit perfectly and didn't require any additional sandin' o' t' fins for fit. Begad! Well, blow me down! 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. Begad!

Assembly o' t' nose cone be unique t' me, me hearties, too. Begad! Blimey! 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. Then t' shoulder is glued onto t' nose cone. Ya scallywag! With respect t' t' shoulder, me hearties, I think it is a bit too short. Avast! Avast, me bucko, me proud beauty! It also required tape t' make it fit snug into t' body tube. Avast! Aye aye!

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

FLIGHT/RECOVERY:

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

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, shiver me timbers, me bucko, t' count down began . . Begad! Begad! . Begad! Blimey! 3, 2, 1!

Ignition took place but t' rocket didn't move, then the booster motor stopped just as t' sustainer ignited. T' sustainer took off quickly. Well, blow me down! Blimey! Begad! Blimey! We were able t' seen t' ejection and t' 12" orange parachute deploy. Aye aye! Blimey! 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 was carried about 1/4 mile away . . . Well, blow me down! 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. Begad! 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. Perfect lift, visible separation and successful sustainer ignition. Avast, me hearties, me proud beauty! Out o' site, arrr, ya bilge rat, trial o' smoke, then a little orange parachute appeared. Ya scallywag! Begad! It was so high, shiver me timbers, I had time t' pick up t' booster and then start walkin' t' where t' sustainer landed. Well, blow me down! Watchin' t' descend rate indicated that I could probably go with a 3" spill hole or tighten up on the shroud lines. Arrr! Aye aye! This kit is a good candidate for a streamer, me bucko, matey, because I can only imagine t' altitude with C6/C6 combination. Begad! Ya scallywag!

Booster is nay only unique looking, 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. Begad! It uses a Keelhaul®©™® tether as already mentioned, me bucko, 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. Begad! Blimey! I love this stuff and have purchased it separately from Rogue for me other kits. Begad! Avast!

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

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. I give t' kit an OVERALL ratin' o' 4 1/2 points.

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

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

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

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! Well, blow me down! I used these thus far, and plan t' try some engines from Apogee later. Ahoy! Avast, me proud beauty! 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. Ahoy! Well, blow me down! I used me usual worm beddin' wadding, just enough t' fill t' diameter o' t' body tube t' about half an inch. Begad! Begad! 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. Ya scallywag! No actual method was provided otherwise with t' kit itself. T' model flies straight and nicely. Ahoy! And t' orange chute supplied looked great.  I wish t' booster had its own recovery system instead o' tumble recovery, me hearties, me hearties, shiver me timbers, though. Aye aye!

Recovery:T' shock cord I modified.  T' kit came with a 36 inch length o' 1/16 inch thick Keelhaul®©™® cording. Ya scallywag! Avast! Blimey! That's fine as a rule, me bucko, but one o' me hangups with shock cords is that t' should stretch to reduce stress on t' shock system. Begad! So, ya bilge rat, I added a 2-foot length o' flat, 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! Blimey! 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, me hearties, matey, which seems common in contact staging. Ahoy! Blimey! Blimey! T' parachute is thin orange nylon, 10 inches in diameter.  Although it's a flat hexagon, arrr, arrr, me hearties, it inflated nicely. Arrr! It seems just right in size, me hearties, shiver me timbers, as t' rocket descends softly.

Flight Rating: 4 out o' 5

Summary:Cool looking, shiver me timbers, flies straight, catchy fin rin' draws attention. Aye aye! Any cons include alignment o' t' booster takin' some determination, but t' result is worth it. Ya scallywag! Well, ya bilge rat, blow me down! T' shock cord wasn't stretchy. Aye aye! 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. Avast, me proud beauty! 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. Begad!

Overall Rating: 3 ½ out o' 5
