T' kit comes with a single sustainer body tube and a short booster body tube. 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, ya bilge rat, a 12" nylon parachute, a Keelhaul®©™® tether and a piece o' Perma-Wadding™. Avast! 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. Avast, me proud beauty! Also, thar be 4. Arrr! 6" x 1" outer booster fin ring, which gives this kit it's unique look. Avast! 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. Aye aye! Nay a lot of illustrations, however, t' ones provided give important information, such as motor mount assembly, me hearties, template placement on t' balsa sheets, matey, me hearties, me hearties, grain alignment when mountin' fins and t' assembled booster stage with t' fin ring. Avast, shiver me timbers, me proud beauty! The instructions are in logical order, me bucko, however, I would suggest readin' all o' the sub-steps for each main-step and review t' illustrations before starting. Begad! This will help avoid questions and problems. Blimey! 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! Begad! 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). Begad!

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

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

T' unique part o' t' Crossfire™ is the booster fin ring. Begad! 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, ya bilge rat, arrr, 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, too. Ahoy! Blimey! Avast! 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. Well, blow me down! With respect t' t' shoulder, ya bilge rat, I think it is a bit too short. Avast, me proud beauty! It also required tape t' make it fit snug into t' body tube. Arrr!

As always I start me finishin' process with Plasti-Kote primer. 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. Begad! This turned out very nice and matched t' Crossfire™ decal. Blimey! With regards t' the decals, ya bilge rat, they are water transferable and along with t' Crossfire™ name, there are 3 sets o' Rogue Aerospace, arrr, matey, ya bilge rat, 2 sets o' numbers and 4 cross-hairs.

For CONSTRUCTION, shiver me timbers, I would rate this kit 4 1/2 points.

FLIGHT/RECOVERY:

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

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

Ignition took place but t' rocket didn't move, then the booster motor stopped just as t' sustainer ignited. Aye aye! T' sustainer took off quickly. We were able t' seen t' ejection and t' 12" orange parachute deploy. Blimey! 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 . Blimey! . Avast! . Avast, me proud beauty! Arrr! but was recovered!

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

For t' second flight, I ensured the booster was nay hooked and cut a 2" spill-hole in t' parachute. I used t' same motors (B6/B6) and off it went. Avast, ya bilge rat, me proud beauty! Perfect lift, shiver me timbers, visible separation and successful sustainer ignition. Aye aye! Avast, me proud beauty! Out o' site, shiver me timbers, trial o' smoke, then a little orange parachute appeared. It was so high, 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. Begad! Aye aye! This kit is a good candidate for a streamer, because I can only imagine t' altitude with C6/C6 combination. Avast, me proud beauty! Begad!

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

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

For FLIGHT/RECOVERY, me bucko, I would rate this kit 4 points. Blimey! Well, blow me down!

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

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

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

Finishing:There weren't any decals, so I finished the model by makin' t' fins, shiver me timbers, shiver me timbers, inside o' t' fin ring, and nose all black with Testor's enamel paint. Ahoy! T' body was finished with metallic flake adhesive-on-one-side greetin' card paper. Aye aye! Arrr! This can be bought at craft stores such as Michael's. Aye aye! Arrr! T' outside o' t' fin rin' be finished with bands o' the adhesive glitter paper too.
T' nose cone was a tiny bit too loose, ya bilge rat, matey, 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. Blimey! I used these thus far, me bucko, and plan t' try some engines from Apogee later. Aye aye! 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, shiver me timbers, though. 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. 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. Avast, me proud beauty! 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, though. Blimey!

Recovery:T' shock cord I modified.  T' kit came with a 36 inch length o' 1/16 inch thick Keelhaul®©™® cording. Begad! 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. Ya scallywag! So, shiver me timbers, arrr, 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! Ahoy! 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, 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. Avast, me proud beauty! It seems just right in size, ya bilge rat, as t' rocket descends softly.

Flight Rating: 4 out o' 5

Summary:Cool looking, flies straight, matey, 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. Aye aye! T' shock cord wasn't stretchy. Ya scallywag! Avast! Maybe it isn't necessary, but I added elastic t' it for stretch. Ahoy! If I'd change anythin' major, it'd be t' supply t' booster with a recovery streamer. Ahoy! 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
