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

CONSTRUCTION:

There are eight pages o' clear instructions. Ya scallywag! Nay a lot of illustrations, arrr, however, t' ones provided give important information, such as motor mount assembly, me bucko, ya bilge rat, me hearties, template placement on t' balsa sheets, grain alignment when mountin' fins and t' assembled booster stage with t' fin ring. Well, blow me down! Ya scallywag! 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! Begad! This will help avoid questions and problems. Begad!   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". Blimey! 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).

T' assembly o' t' Crossfire™ was straight forward and did nay pose any major problems. All o' t' parts fit correctly. 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. Aye aye! Be very careful with t' 1/16" balsa for t' sustainer fins . . Begad! Avast! . Avast, me proud beauty! this is some flimsy stuff until it is sealed with CA or primer. Aye aye! And even though t' instructions call it optional, shiver me timbers, 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. Aye aye! Ahoy! I broke t' fin along t' grain and had to glue back on with CA while finishing.

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

T' unique part o' t' Crossfire™ is the booster fin ring. Arrr! My rin' fit perfectly and didn't require any additional sandin' o' t' fins for fit. Begad! 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. Avast! Blimey!

Assembly o' t' nose cone was unique t' me, shiver me timbers, too. You drill (with a hobby knife) a small hole in t' shoulder t' allow t' Keelhaul®©™® tether t' pass through. Begad! Ya scallywag! 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. Avast! With respect t' t' shoulder, ya bilge rat, I think it is a bit too short. It also required tape t' make it fit snug into t' body tube. Well, blow me down! Arrr!

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

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

FLIGHT/RECOVERY:

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

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

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

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

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

Overall, 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. Well, blow me down! I give t' kit an OVERALL ratin' o' 4 1/2 points.

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

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

Finishing:There weren't any decals, shiver me timbers, so I finished the model by makin' t' fins, shiver me timbers, inside o' t' fin ring, and nose all black with Testor's enamel paint. Well, blow me down! Begad! T' body was finished with metallic flake adhesive-on-one-side greetin' card paper. Begad! This can be bought at craft stores such as Michael's. Arrr! 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. 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. I used these thus far, and plan t' try some engines from Apogee later. Ya scallywag! 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. I used me usual worm beddin' wadding, just enough t' fill t' diameter o' t' body tube t' about half an inch. Begad! Well, me bucko, blow me down! 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. Ahoy! Well, blow me down! 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. Arrr! Avast!

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! Ahoy! 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. So, 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. Well, blow me down! T' knot is made inside t' nose cone before its two halves are assembled. Ya scallywag! Avast, me proud beauty! T' rocket so far has suffered no wear or damage, except some slight scorchin' o' the booster, shiver me timbers, which seems common in contact staging. Ya scallywag! T' parachute is thin orange nylon, 10 inches in diameter.  Although it's a flat hexagon, me hearties, it inflated nicely. It seems just right in size, as t' rocket descends softly.

Flight Rating: 4 out o' 5

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

Overall Rating: 3 ½ out o' 5
