T' kit comes with a single sustainer body tube and a short booster body tube. Avast, me proud beauty! 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, shiver me timbers, arrr, a Keelhaul®©™® tether and a piece o' Perma-Wadding™. Aye aye! For the fins, shiver me timbers, thar are two balsa sheets, me hearties, a 3/32" and a 1/16", ya bilge rat, shiver me timbers, and templates to cut out t' four fins for each section. Avast, shiver me timbers, me proud beauty! Also, thar be 4. Ahoy! Aye aye! 6" x 1" outer booster fin ring, which gives this kit it's unique look. Lastly thar is a set o' water transfer decals with a large gold Crossfire™ decal and various others. Ya scallywag!

CONSTRUCTION:

There are eight pages o' clear instructions. Nay a lot of illustrations, however, matey, ya bilge rat, t' ones provided give important information, shiver me timbers, such as motor mount assembly, template placement on t' balsa sheets, me hearties, me bucko, grain alignment when mountin' fins and t' assembled booster stage with t' fin ring. Begad! 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. Avast, me proud beauty! Aye aye! This will help avoid questions and problems. Blimey! Avast!   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". Avast! T' "front" o' t' tube is marked in t' bottom illustration. Blimey! 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). Avast, shiver me timbers, me proud beauty!

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

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

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

Assembly o' t' nose cone was 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. Aye aye! This is tied t' a retainer (small bead) which prevents it from passin' back through t' hole. Begad! Then t' shoulder is glued onto t' nose cone. Ya scallywag! With respect t' t' shoulder, arrr, I think it is a bit too short. Avast! It also required tape t' make it fit snug into t' body tube. Ahoy!

As always I start me finishin' process with Plasti-Kote primer. Avast, me proud beauty! 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. Avast, me proud beauty! This turned out very nice and matched t' Crossfire™ decal. Avast, me proud beauty! Arrr! With regards t' the decals, matey, ya bilge rat, 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, arrr, I would rate this kit 4 1/2 points. Avast!

FLIGHT/RECOVERY:

T' Crossfire™ is nay your standard two-stage kit. Avast, me proud beauty! T' two motors are nay taped together. Ahoy! 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. Well, blow me down! Avast, me proud beauty!

T' maiden voyage was 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. Aye aye! With everythin' set, shiver me timbers, t' count down began . Blimey! Blimey! . Avast! . Blimey! Blimey! 3, me hearties, matey, 2, 1!

Ignition took place but t' rocket didn't move, then the booster motor stopped just as t' sustainer ignited. Avast! T' sustainer took off quickly. 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. Aye aye! This rocket be carried about 1/4 mile away . . Begad! Begad! . Begad! 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. Avast! Ya scallywag! Nay only that, me hearties, but it burned a hole right through me blast shield. Well, blow me down!

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

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

I just want t' mention this kit's recovery system. Arrr! 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. Avast, me proud beauty! I love this stuff and have purchased it separately from Rogue for me other kits. Ahoy! Blimey!

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

Overall, me hearties, 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. Begad! 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.

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

Finishing:There weren't any decals, so I finished the model by makin' t' fins, inside o' t' fin ring, me hearties, and nose all black with Testor's enamel paint. Ahoy! 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. Ahoy! Begad! 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. Aye aye! Avast, me proud beauty! 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. Avast, me proud beauty! I used these thus far, me bucko, and plan t' try some engines from Apogee later. Avast! 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, ya bilge rat, shiver me timbers, though. Begad! Begad! I used me usual worm beddin' wadding, just enough t' fill t' diameter o' t' body tube t' about half an inch. The engines were retained with a motor block in t' sustainer with a tape band around t' aft end o' t' sustainer's motor, shiver me timbers, and tape for t' aft end o' the booster's engine. Ya scallywag! No actual method be provided otherwise with t' kit itself. T' model flies straight and nicely. Avast! And t' orange chute supplied looked great.  I wish t' booster had its own recovery system instead o' tumble recovery, arrr, 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. Begad! Blimey! Arrr! Blimey! That's fine as a rule, shiver me timbers, but one o' me hangups with shock cords is that t' should stretch to reduce stress on t' shock system. Well, blow me down! Blimey! Avast! Blimey! So, I added a 2-foot length o' flat, me bucko, ya bilge rat, 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. Ya scallywag! Blimey! T' knot is made inside t' nose cone before its two halves are assembled. Avast, me proud beauty! Blimey! Aye aye! Blimey! T' rocket so far has suffered no wear or damage, shiver me timbers, except some slight scorchin' o' the booster, shiver me timbers, matey, which seems common in contact staging. T' parachute is thin orange nylon, ya bilge rat, 10 inches in diameter.  Although it's a flat hexagon, it inflated nicely. Avast, me proud beauty! Blimey! Blimey! Blimey! It seems just right in size, shiver me timbers, as t' rocket descends softly. Begad! Blimey!

Flight Rating: 4 out o' 5

Summary:Cool looking, flies straight, catchy fin rin' draws attention. Arrr! Blimey! Any cons include alignment o' t' booster takin' some determination, but t' result is worth it. Blimey! Blimey! Well, blow me down! Blimey! Blimey! Blimey! T' shock cord wasn't stretchy. Avast! Blimey! Avast, me proud beauty! Blimey! Blimey! Blimey! Maybe it isn't necessary, me hearties, 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. Aye aye! Blimey! Aye aye! Blimey! 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. Begad! Blimey! Blimey! Blimey!
