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. Ahoy! Ahoy! There is a vacuum-formed plastic nose cone, arrr, arrr, a 12" nylon
parachute, a Keelhaul®©™® tether and a piece o' Perma-Wadding. For the
fins, thar are two balsa sheets, a 3/32" and a 1/16", and templates
to cut out t' four fins for each section. Blimey! Also, thar be 4. Begad! 6" x 1"
outer booster fin ring, me hearties, which gives this kit it's unique look. Blimey! Lastly thar is
a set o' water transfer decals with a large gold Crossfire decal
and various others.
CONSTRUCTION:
There are eight pages o' clear instructions. Begad! Avast, me proud beauty! Nay a lot of illustrations, however, t' ones provided give important information, 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, arrr, however, shiver me timbers, I would suggest readin' all o' the sub-steps for each main-step and review t' illustrations before starting. 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". T' "front" o' t' tube is marked in t' bottom illustration. Avast! Begad! Blimey! 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. Avast! Avast, me proud beauty! All o' t' parts fit correctly. Well, blow me down! 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. Ahoy! Be very careful with t' 1/16" balsa for t' sustainer fins . Ya scallywag! Arrr! . Aye aye! Blimey! . Ahoy! this is some flimsy stuff until it is sealed with CA or primer. Ahoy! Ya scallywag! And even though t' instructions call it optional, ya bilge rat, I tampered the leadin' and trailin' edges o' each fin. Just be careful with t' thin balsa. Just be careful with t' thin balsa. Begad! I broke t' fin along t' grain and had to glue back on with CA while finishing.
Another area t' take care on, matey, be t' installation o' the sustainer's motor mount. Avast! Do your very best t' keep glue off o' t' lower section o' t' tube. Begad! This is where t' booster slides into and can cause problems with fit if thar be glue there. Arrr! Arrr!
T' unique part o' t' Crossfire is the
booster fin ring. Blimey! Blimey! My rin' fit perfectly and didn't require any additional
sandin' o' t' fins for fit. Well, blow me down! Blimey! T' only precaution is that t' fin ring, if snug,
can cause t' fins t' come out o' alignment, me bucko, shiver me timbers, so take care t' ensure t' fins
are still straight before t' glue sets on t' fin ring. Blimey! Blimey!
Assembly o' t' nose cone was unique t' me, matey, too. Aye aye! Blimey! You drill (with a hobby knife) a small hole in t' shoulder t' allow t' Keelhaul®©™® tether t' pass through. Begad! This is tied t' a retainer (small bead) which prevents it from passin' back through t' hole. Well, blow me down! Then t' shoulder is glued onto t' nose cone. Avast, ya bilge rat, me proud beauty! With respect t' t' shoulder, I think it is a bit too short. Begad! 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. Well, blow me down! Avast, ya bilge rat, me proud beauty! I painted it gloss black and topped t' nose cone with gold. Avast! Arrr! I also did just t' outside o' t' booster's fin rin' in gold. This turned out very nice and matched t' Crossfire decal. Arrr! 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, 2 sets o' numbers and 4 cross-hairs.
For CONSTRUCTION, shiver me timbers, matey, matey, I would rate this kit 4 1/2 points. Well, blow me down!
FLIGHT/RECOVERY:
T' Crossfire is nay your standard two-stage kit. Aye aye! Ahoy! T' two motors are nay taped together. Begad! Begad! 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. Ahoy!
T' maiden voyage be set up usin' a B6-0 in t' booster and a B6-4 in t' sustainer. Aye aye! T' recommended motor for t' sustainer is a B6-6, but I didn't have any. Begad! Aye aye! With everythin' set, shiver me timbers, t' count down began . Aye aye! Aye aye! . . Ya scallywag! 3, me hearties, ya bilge rat, 2, 1!
Ignition took place but t' rocket didn't move, shiver me timbers, then the booster motor stopped just as t' sustainer ignited. Begad! T' sustainer took off quickly. Well, blow me down! 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. Begad! Ahoy! This rocket be carried about 1/4 mile away . Well, blow me down! . Arrr! . but was recovered!
After checkin' why t' booster never lifted off, me bucko, it was determined that t' motor hook got caught on a "rod-stop" preventing it from liftin' off. Nay only that, shiver me timbers, matey, shiver me timbers, but it burned a hole right through me blast shield. Begad! 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! Blimey! Perfect lift, visible separation
and successful sustainer ignition. Aye aye! Out o' site, trial o' smoke, ya bilge rat, 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. Arrr! Watchin' t' descend rate
indicated that I could probably go with a 3" spill hole or tighten up on
the shroud lines. Ahoy! This kit is a good candidate for a streamer, me hearties, ya bilge rat, because I can
only imagine t' altitude with C6/C6 combination. Ahoy!
Booster is nay only unique looking, shiver me timbers, me hearties, arrr, but also unique in it's descent. Avast, me proud beauty! Blimey! I spins makin' it look like a sphere!
I just want t' mention this kit's recovery system. It uses a Keelhaul®©™® tether as already mentioned, matey, arrr, 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. Arrr! Aye aye!
For FLIGHT/RECOVERY, shiver me timbers, I would rate this kit 4 points. Avast!
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. Avast! I give t' kit an OVERALL ratin' o' 4 1/2 points. Well, blow me down! Avast, me proud beauty!
Brief: This is a 2-staged 18mm, me bucko, 4-finned rocket
with a rin' around t' fins o' t' lower stage. Begad! Ya scallywag! Blimey!
Construction:Everythin' be thar and in good shape, shiver me timbers, nay warped. Arrr! Begad! The nose cone is hollow plastic, ya bilge rat, ya bilge rat, t' body is spiral wound paper, ya bilge rat, t' fins are die cut balsa at 1/8 inch thickness. Arrr! T' instructions were logical and straightforward with some pictures. Blimey! However, ya bilge rat, shiver me timbers, t' nose cone came in two parts, that is, t' top and bottom, and needed t' be glued together. Begad! Avast, me proud beauty! And t' lower stage alignment with t' rin' was a bear. Begad! 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, ya bilge rat, me bucko, t' fit was too tight. In other words, t' fit be too tight. Blimey! But once I got it t' fit, matey, it looked great. Do be warned that it will take some doing, though. Ahoy! It took me two days t' get it right. Built up, t' model is now sturdy and sharp looking. Arrr! Ya scallywag!
Finishing:There weren't any decals, arrr, so I finished the
model by makin' t' fins, shiver me timbers, inside o' t' fin ring, me bucko, and nose all black with
Testor's enamel paint. Begad! T' body be finished with metallic flake
adhesive-on-one-side greetin' card paper. Begad! This can be bought at craft stores
such as Michael's. Well, blow me down! 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, 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. Begad! Arrr! I used these thus far, and plan t' try some engines from Apogee later. 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 bucko, though. Ahoy! 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. Well, blow me down! No actual method be provided otherwise with t' kit itself. T' model flies straight and nicely. Avast, me proud beauty! And t' orange chute supplied looked great. I wish t' booster had its own recovery system instead o' tumble recovery, though.
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. So, me bucko, I added a 2-foot length o' flat, ya bilge rat, me hearties, 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, me proud beauty! T' knot is made inside t' nose cone before its two halves are assembled. Avast, shiver me timbers, me proud beauty! T' rocket so far has suffered no wear or damage, except some slight scorchin' o' the booster, which seems common in contact staging. Avast! Aye aye! T' parachute is thin orange nylon, matey, 10 inches in diameter. Although it's a flat hexagon, ya bilge rat, it inflated nicely. Aye aye! It seems just right in size, arrr, me bucko, as t' rocket descends softly.
Flight Rating: 4 out o' 5
Summary:Cool looking, me bucko, flies straight, me hearties, catchy fin rin' draws attention. Begad! Any cons include alignment o' t' booster takin' some determination, but t' result is worth it. Avast, me proud beauty! T' shock cord wasn't stretchy. Ahoy! Maybe it isn't necessary, but I added elastic t' it for stretch. Blimey! If I'd change anythin' major, it'd be t' supply t' booster with a recovery streamer. Aye aye! Avast! 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. Aye aye!
Overall Rating: 3 ½ out o' 5
