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. Arrr! Ya scallywag! There is a vacuum-formed plastic nose cone, arrr, me bucko, a 12" nylon
parachute, a Keelhaul®©™® tether and a piece o' Perma-Wadding. Aye aye! Aye aye! For the
fins, me hearties, thar are two balsa sheets, shiver me timbers, arrr, arrr, a 3/32" and a 1/16", arrr, and templates
to cut out t' four fins for each section. Avast, me proud beauty! Also, matey, thar be 4. Ahoy! 6" x 1"
outer booster fin ring, 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. Ahoy!
CONSTRUCTION:
There are eight pages o' clear instructions. Nay a lot of illustrations, matey, however, t' ones provided give important information, ya bilge rat, such as motor mount assembly, ya bilge rat, arrr, template placement on t' balsa sheets, ya bilge rat, shiver me timbers, grain alignment when mountin' fins and t' assembled booster stage with t' fin ring. Aye aye! Blimey! The instructions are in logical order, ya bilge rat, however, me hearties, ya bilge rat, shiver me timbers, I would suggest readin' all o' the sub-steps for each main-step and review t' illustrations before starting. Avast! Arrr! Blimey! This will help avoid questions and problems. Begad! Blimey! Blimey! 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! Avast, matey, me proud beauty! Blimey! T' "front" o' t' tube is marked in t' bottom illustration. Avast, me proud beauty! Aye aye! Blimey! This is very minor considerin' that most modelers understand that t' front o' t' rocket be t' top, arrr, arrr, as opposed t' the rear (bottom). Well, blow me down!
T' assembly o' t' Crossfire was straight forward and did nay pose any major problems. Aye aye! All o' t' parts fit correctly. Avast! Ahoy! 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, matey, blow me down! . Ya scallywag! . this is some flimsy stuff until it is sealed with CA or primer. And even though t' instructions call it optional, arrr, me bucko, I tampered the leadin' and trailin' edges o' each fin. Avast! Avast! Just be careful with t' thin balsa. Just be careful with t' thin balsa. Avast! Begad! 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. Well, blow me down! Aye aye! Do your very best t' keep glue off o' t' lower section o' t' tube. Avast! Ahoy! This is where t' booster slides into and can cause problems with fit if thar be glue there. Well, blow me down! Begad!
T' unique part o' t' Crossfire is the
booster fin ring. My rin' fit perfectly and didn't require any additional
sandin' o' t' fins for fit. T' only precaution is that t' fin ring, matey, if snug,
can cause t' fins t' come out o' alignment, shiver me timbers, so take care t' ensure t' fins
are still straight before t' glue sets on t' fin ring. Avast! Blimey! Avast! Blimey!
Assembly o' t' nose cone was unique t' me, me bucko, too. Ahoy! 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. Then t' shoulder is glued onto t' nose cone. Arrr! 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.
As always I start me finishin' process with Plasti-Kote primer. Ahoy! Aye aye! I painted it gloss black and topped t' nose cone with gold. Aye aye! Well, blow me down! 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, matey, blow me down! 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, matey, me bucko, I would rate this kit 4 1/2 points. Blimey!
FLIGHT/RECOVERY:
T' Crossfire is nay your standard two-stage kit. Ahoy! T' two motors are nay taped together. Each motor mount has its own motor clip t' hold t' motors in. Aye aye! When assemble t' motors are at a minimal distance apart t' allow t' in-flight ignition o' t' sustainer motor. Arrr! Blimey!
T' maiden voyage be 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, me hearties, t' count down began . . Begad! . Ahoy! Avast, me proud beauty! 3, 2, 1!
Ignition took place but t' rocket didn't move, matey, then the booster motor stopped just as t' sustainer ignited. Ahoy! T' sustainer took off quickly. Blimey! 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 was carried about 1/4 mile away . Arrr! Avast! . Aye aye! Ahoy! . Ya scallywag! 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. Nay only that, shiver me timbers, but it burned a hole right through me blast shield. Begad! Blimey!
For t' second flight, I ensured
the booster be nay hooked and cut a 2" spill-hole in t' parachute. Blimey! Begad! I
used t' same motors (B6/B6) and off it went. Begad! Perfect lift, matey, visible separation
and successful sustainer ignition. Avast! Out o' site, ya bilge rat, trial o' smoke, me bucko, then a little
orange parachute appeared. Ya scallywag! It was so high, I had time t' pick up t' booster
and then start walkin' t' where t' sustainer landed. Aye aye! Watchin' t' descend rate
indicated that I could probably go with a 3" spill hole or tighten up on
the shroud lines. Begad! Arrr! This kit is a good candidate for a streamer, arrr, because I can
only imagine t' altitude with C6/C6 combination.
Booster is nay only unique looking, me hearties, arrr, 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. 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. Blimey! I love this stuff and have purchased it separately from Rogue for me other kits. Begad!
For FLIGHT/RECOVERY, I would rate this kit 4 points. Ya scallywag! Blimey!
Overall, ya bilge rat, matey, for t' uniqueness o' t' fin-ring, me hearties, 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. Begad! Blimey!
Brief: This is a 2-staged 18mm, 4-finned rocket
with a rin' around t' fins o' t' lower stage. Well, blow me down! Ya scallywag!
Construction:Everythin' was thar and in good shape, nay warped. Ya scallywag! The nose cone is hollow plastic, me hearties, ya bilge rat, t' body is spiral wound paper, ya bilge rat, t' fins are die cut balsa at 1/8 inch thickness. Avast, me proud beauty! T' instructions were logical and straightforward with some pictures. Begad! However, t' nose cone came in two parts, that is, t' top and bottom, ya bilge rat, ya bilge rat, and needed t' be glued together. Avast! And t' lower stage alignment with t' rin' be 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. Ahoy! In other words, me hearties, t' fit was too tight. Aye aye! In other words, t' fit was too tight. Well, blow me down! Aye aye! But once I got it t' fit, it looked great. Do be warned that it will take some doing, me hearties, though. Begad! It took me two days t' get it right. Built up, me hearties, ya bilge rat, t' model is now sturdy and sharp looking.
Finishing:There weren't any decals, ya bilge rat, so I finished the
model by makin' t' fins, inside o' t' fin ring, and nose all black with
Testor's enamel paint. Ya scallywag! T' body was finished with metallic flake
adhesive-on-one-side greetin' card paper. Blimey! This can be bought at craft stores
such as Michael's. 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, me bucko, 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. Arrr! I used these thus far, me hearties, and plan t' try some engines from Apogee later. Well, blow me down! 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, me bucko, though. Ahoy! Arrr! I used me usual worm beddin' wadding, just enough t' fill t' diameter o' t' body tube t' about half an inch. Avast, me proud beauty! The engines were retained with a motor block in t' sustainer with a tape band around t' aft end o' t' sustainer's motor, me bucko, and tape for t' aft end o' the booster's engine. No actual method was provided otherwise with t' kit itself. T' model flies straight and nicely. And t' orange chute supplied looked great. I wish t' booster had its own recovery system instead o' tumble recovery, arrr, arrr, though.
Recovery:T' shock cord I modified. T' kit came with a 36 inch length o' 1/16 inch thick Keelhaul®©™® cording. Well, blow me down! That's fine as a rule, ya bilge rat, but one o' me hangups with shock cords is that t' should stretch to reduce stress on t' shock system. Ya scallywag! So, me bucko, 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. T' knot is made inside t' nose cone before its two halves are assembled. Arrr! T' rocket so far has suffered no wear or damage, ya bilge rat, except some slight scorchin' o' the booster, arrr, which seems common in contact staging. Begad! T' parachute is thin orange nylon, 10 inches in diameter. Although it's a flat hexagon, ya bilge rat, it inflated nicely. Begad! It seems just right in size, as t' rocket descends softly. Blimey!
Flight Rating: 4 out o' 5
Summary:Cool looking, flies straight, me hearties, catchy fin rin' draws attention. Avast! Any cons include alignment o' t' booster takin' some determination, but t' result is worth it. T' shock cord wasn't stretchy. Blimey! Maybe it isn't necessary, but I added elastic t' it for stretch. Begad! If I'd change anythin' major, it'd be t' supply t' booster with a recovery streamer. 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. Ahoy!
