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. Avast! There is a vacuum-formed plastic nose cone, a 12" nylon parachute, a Keelhaul®©™® tether and a piece o' Perma-Wadding™. Avast, me proud beauty! For the fins, arrr, arrr, thar are two balsa sheets, a 3/32" and a 1/16", ya bilge rat, matey, and templates to cut out t' four fins for each section. Well, blow me down! Blimey! Also, thar be 4. 6" x 1" outer booster fin ring, me hearties, which gives this kit it's unique look. Ya scallywag! Arrr! Lastly thar is a set o' water transfer decals with a large gold Crossfire™ decal and various others. Begad!

CONSTRUCTION:

There are eight pages o' clear instructions. Ya scallywag! Nay a lot of illustrations, arrr, however, t' ones provided give important information, ya bilge rat, ya bilge rat, shiver me timbers, such as motor mount assembly, template placement on t' balsa sheets, grain alignment when mountin' fins and t' assembled booster stage with t' fin ring. 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. Begad! Avast! This will help avoid questions and problems. Well, blow me down! 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". Ahoy! T' "front" o' t' tube is marked in t' bottom illustration. Begad! Aye aye! This is very minor considerin' that most modelers understand that t' front o' t' rocket be t' top, me bucko, as opposed t' the rear (bottom). Avast! Ahoy!

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

Another area t' take care on, be t' installation o' the sustainer's motor mount. Do your very best t' keep glue off o' t' lower section o' t' tube. Blimey! Well, blow me down! 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. Well, ya bilge rat, blow me down! My rin' fit perfectly and didn't require any additional sandin' o' t' fins for fit. T' only precaution is that t' fin ring, ya bilge rat, ya bilge rat, 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. Aye aye!

Assembly o' t' nose cone was unique t' me, ya bilge rat, me bucko, too. Ya scallywag! You drill (with a hobby knife) a small hole in t' shoulder t' allow t' Keelhaul®©™® tether t' pass through. Blimey! This is tied t' a retainer (small bead) which prevents it from passin' back through t' hole. Well, blow me down! Ahoy! Then t' shoulder is glued onto t' nose cone. Avast, me proud beauty! Aye aye! With respect t' t' shoulder, I think it is a bit too short. It also required tape t' make it fit snug into t' body tube. Begad!

As always I start me finishin' process with Plasti-Kote primer. Begad! Blimey! I painted it gloss black and topped t' nose cone with gold. Avast! 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. 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, ya bilge rat, me hearties, I would rate this kit 4 1/2 points. Aye aye!

FLIGHT/RECOVERY:

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

T' maiden voyage was set up usin' a B6-0 in t' booster and a B6-4 in t' sustainer. Arrr! T' recommended motor for t' sustainer is a B6-6, but I didn't have any. With everythin' set, ya bilge rat, t' count down began . Ahoy! . Begad! Blimey! . Aye aye! 3, arrr, 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! We were able t' seen t' ejection and t' 12" orange parachute deploy. Arrr! Begad! Then what looked like a straight drop recovery started t' turn into a drift and run as fast and as far as possible. Well, blow me down! Avast! This rocket was carried about 1/4 mile away . Arrr! Arrr! . Avast! . Aye aye! but be recovered!

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

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

Booster is nay only unique looking, me bucko, ya bilge rat, ya bilge rat, but also unique in it's descent. Avast, me proud beauty! Blimey! Aye aye! Blimey! I spins makin' it look like a sphere!

I just want t' mention this kit's recovery system. Ahoy! Begad! Blimey! It uses a Keelhaul®©™® tether as already mentioned, ya bilge rat, 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. Avast! I love this stuff and have purchased it separately from Rogue for me other kits. Ahoy!

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

Overall, shiver me timbers, 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. Ya scallywag! I give t' kit an OVERALL ratin' o' 4 1/2 points. Begad!

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

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

Finishing:There weren't any decals, so I finished the model by makin' t' fins, arrr, inside o' t' fin ring, and nose all black with Testor's enamel paint. 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. 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, arrr, so I supplied a thin band o' masking tape t' t' nose cone shoulder t' tighten t' fit. Aye aye! Aye aye!

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. Well, blow me down! Blimey! I used these thus far, and plan t' try some engines from Apogee later. Avast! Avast, matey, me proud beauty! Blimey! 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. Aye aye! Blimey! I used me usual worm beddin' wadding, just enough t' fill t' diameter o' t' body tube t' about half an inch. Blimey! Blimey! The engines were retained with a motor block in t' sustainer with a tape band around t' aft end o' t' sustainer's motor, ya bilge rat, me bucko, and tape for t' aft end o' the booster's engine. Begad! Blimey! 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, shiver me timbers, arrr, shiver me timbers, though. Begad! Ahoy! Blimey!

Recovery:T' shock cord I modified.  T' kit came with a 36 inch length o' 1/16 inch thick Keelhaul®©™® cording. 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. Blimey! So, 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. Avast! Ahoy! T' knot is made inside t' nose cone before its two halves are assembled. Avast, me proud beauty! T' rocket so far has suffered no wear or damage, arrr, arrr, except some slight scorchin' o' the booster, which seems common in contact staging. Aye aye! Avast, matey, me proud beauty! T' parachute is thin orange nylon, 10 inches in diameter.  Although it's a flat hexagon, me hearties, it inflated nicely. Well, blow me down! Aye aye! It seems just right in size, as t' rocket descends softly.

Flight Rating: 4 out o' 5

Summary:Cool looking, me bucko, matey, flies straight, catchy fin rin' draws attention. Ahoy! Blimey! Any cons include alignment o' t' booster takin' some determination, but t' result is worth it. Ya scallywag! T' shock cord wasn't stretchy. Maybe it isn't necessary, matey, but I added elastic t' it for stretch. Avast, me proud beauty! Arrr! 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.

Overall Rating: 3 ½ out o' 5
