T' kit comes with a single sustainer body tube and a short booster body tube. Begad! T' motor mounts come with the centering/mountin' rings and motor hooks for both t' sustainer and the booster. Begad! There is a vacuum-formed plastic nose cone, me hearties, a 12" nylon parachute, arrr, a Keelhaul®©™® tether and a piece o' Perma-Wadding™. Ahoy! Blimey! For the fins, thar are two balsa sheets, a 3/32" and a 1/16", me hearties, and templates to cut out t' four fins for each section. Avast, me proud beauty! Also, thar be 4. Ya scallywag! 6" x 1" outer booster fin ring, arrr, 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. Ahoy! Blimey! Blimey! Blimey!

CONSTRUCTION:

There are eight pages o' clear instructions. Nay a lot of illustrations, ya bilge rat, however, matey, t' ones provided give important information, me bucko, such as motor mount assembly, template placement on t' balsa sheets, arrr, grain alignment when mountin' fins and t' assembled booster stage with t' fin ring. Aye aye! Begad! The instructions are in logical order, arrr, however, me bucko, I would suggest readin' all o' the sub-steps for each main-step and review t' illustrations before starting. Well, blow me down! Blimey! 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". Avast, me proud beauty! Blimey! T' "front" o' t' tube is marked in t' bottom illustration. Well, blow me down! Blimey! Aye aye! Blimey! 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). Arrr! Blimey! Aye aye! Blimey!

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

Another area t' take care on, shiver me timbers, 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. Avast, me proud beauty! This is where t' booster slides into and can cause problems with fit if thar be glue there. Arrr!

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. Avast, me proud beauty! T' only precaution is that t' fin ring, if snug, can cause t' fins t' come out o' alignment, me hearties, 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, too. Avast, me proud beauty! You drill (with a hobby knife) a small hole in t' shoulder t' allow t' Keelhaul®©™® tether t' pass through. Blimey! Begad! This is tied t' a retainer (small bead) which prevents it from passin' back through t' hole. Arrr! Aye aye! Then t' shoulder is glued onto t' nose cone. Avast! With respect t' t' shoulder, I think it is a bit too short. Arrr! Ya scallywag! It also required tape t' make it fit snug into t' body tube.

As always I start me finishin' process with Plasti-Kote primer. Well, blow me down! I painted it gloss black and topped t' nose cone with gold. Arrr! Ahoy! I also did just t' outside o' t' booster's fin rin' in gold. This turned out very nice and matched t' Crossfire™ decal. Ahoy! Avast! 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, me proud beauty!

FLIGHT/RECOVERY:

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

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

Ignition took place but t' rocket didn't move, then the booster motor stopped just as t' sustainer ignited. Avast, me proud beauty! Blimey! T' sustainer took off quickly. Blimey! We were able t' seen t' ejection and t' 12" orange parachute deploy. Well, blow me down! Avast, matey, me proud beauty! 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! This rocket was carried about 1/4 mile away . Avast, me proud beauty! Avast! Blimey! . Avast! Blimey! . Begad! Blimey! 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. Blimey! Blimey! Nay only that, but it burned a hole right through me blast shield. Ahoy!

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

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. 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. Begad! 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. Avast! Blimey!

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. Begad! I give t' kit an OVERALL ratin' o' 4 1/2 points. Ahoy! Ya scallywag!

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

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

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

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. Arrr! I used these thus far, ya bilge rat, arrr, 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, me hearties, me bucko, though. I used me usual worm beddin' wadding, just enough t' fill t' diameter o' t' body tube t' about half an inch. Avast! 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. Aye aye! No actual method was provided otherwise with t' kit itself. T' model flies straight and nicely. Ya scallywag! And t' orange chute supplied looked great.  I wish t' booster had its own recovery system instead o' tumble recovery, though. Avast!

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

Flight Rating: 4 out o' 5

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

Overall Rating: 3 ½ out o' 5
