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. Begad! There is a vacuum-formed plastic nose cone, a 12" nylon
parachute, a Keelhaul®©™® tether and a piece o' Perma-Wadding. For the
fins, me hearties, shiver me timbers, thar are two balsa sheets, me bucko, a 3/32" and a 1/16", matey, and templates
to cut out t' four fins for each section. Aye aye! Also, matey, shiver me timbers, thar be 4. 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.
CONSTRUCTION:
There are eight pages o' clear instructions. Blimey! Blimey! Nay a lot of illustrations, ya bilge rat, however, arrr, t' ones provided give important information, such as motor mount assembly, arrr, template placement on t' balsa sheets, grain alignment when mountin' fins and t' assembled booster stage with t' fin ring. Arrr! 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. Blimey! Begad! Blimey! This will help avoid questions and problems. 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". Avast, me proud beauty! T' "front" o' t' tube is marked in t' bottom illustration. Begad! This is very minor considerin' that most modelers understand that t' front o' t' rocket be t' top, shiver me timbers, as opposed t' the rear (bottom). Begad!
T' assembly o' t' Crossfire was straight forward and did nay pose any major problems. 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 be along t' top leadin' edge. This will provide t' most strength. Avast, me proud beauty! Arrr! Be very careful with t' 1/16" balsa for t' sustainer fins . . . Avast, me proud beauty! this is some flimsy stuff until it is sealed with CA or primer. Begad! 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. Arrr! I broke t' fin along t' grain and had to glue back on with CA while finishing. Begad!
Another area t' take care on, me bucko, be t' installation o' the sustainer's motor mount. Begad! 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. Blimey! Avast!
T' unique part o' t' Crossfire is the
booster fin ring. Arrr! My rin' fit perfectly and didn't require any additional
sandin' o' t' fins for fit. Begad! Arrr! T' only precaution is that t' fin ring, 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. Ahoy! Begad!
Assembly o' t' nose cone was unique t' me, too. Begad! You drill (with a hobby knife) a small hole in t' shoulder t' allow t' Keelhaul®©™® tether t' pass through. Arrr! Blimey! This is tied t' a retainer (small bead) which prevents it from passin' back through t' hole. Ahoy! Blimey! Then t' shoulder is glued onto t' nose cone. With respect t' t' shoulder, me bucko, matey, I think it is a bit too short. Avast! Blimey! It also required tape t' make it fit snug into t' body tube. Avast! Blimey!
As always I start me finishin' process with Plasti-Kote primer. Avast, me proud beauty! Avast! I painted it gloss black and topped t' nose cone with gold. 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. Arrr! Arrr! Blimey! 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. Ya scallywag! Blimey!
FLIGHT/RECOVERY:
T' Crossfire is nay your standard two-stage kit. Avast! T' two motors are nay taped together. Avast! Begad! Each motor mount has its own motor clip t' hold t' motors in. Begad! Ya scallywag! 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. Blimey! T' recommended motor for t' sustainer is a B6-6, but I didn't have any. Avast! Blimey! With everythin' set, t' count down began . . . Aye aye! 3, shiver me timbers, 2, 1!
Ignition took place but t' rocket didn't move, me bucko, ya bilge rat, then the booster motor stopped just as t' sustainer ignited. Avast, me proud beauty! Blimey! T' sustainer took off quickly. Begad! Blimey! Arrr! Blimey! We were able t' seen t' ejection and t' 12" orange parachute deploy. Begad! Blimey! Arrr! Blimey! Then what looked like a straight drop recovery started t' turn into a drift and run as fast and as far as possible. This rocket be carried about 1/4 mile away . Ahoy! Blimey! . Blimey! Blimey! . Blimey! 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. Nay only that, me bucko, me hearties, but it burned a hole right through me blast shield.
For t' second flight, ya bilge rat, me bucko, I ensured
the booster was nay hooked and cut a 2" spill-hole in t' parachute. Avast! Blimey! I
used t' same motors (B6/B6) and off it went. Blimey! Blimey! Perfect lift, shiver me timbers, visible separation
and successful sustainer ignition. Ya scallywag! Blimey! Out o' site, trial o' smoke, ya bilge rat, then a little
orange parachute appeared. Begad! Blimey! Arrr! Blimey! It be so high, me hearties, I had time t' pick up t' booster
and then start walkin' t' where t' sustainer landed. Well, matey, 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. Blimey! Blimey! Avast, shiver me timbers, me proud beauty! Blimey! This kit is a good candidate for a streamer, because I can
only imagine t' altitude with C6/C6 combination. Arrr! Blimey! Avast, me proud beauty! Blimey!
Booster is nay only unique looking, ya bilge rat, but also unique in it's descent. Arrr! Avast, me hearties, me proud beauty! Blimey! I spins makin' it look like a sphere!
I just want t' mention this kit's recovery system. Ya scallywag! Blimey! It uses a Keelhaul®©™® tether as already mentioned, me hearties, shiver me timbers, 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. Ya scallywag! Blimey! I love this stuff and have purchased it separately from Rogue for me other kits. Aye aye!
For FLIGHT/RECOVERY, I would rate this kit 4 points. Avast, me proud beauty! Begad!
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! Aye aye! I give t' kit an OVERALL ratin' o' 4 1/2 points. Blimey!
Brief: This is a 2-staged 18mm, 4-finned rocket
with a rin' around t' fins o' t' lower stage. Arrr!
Construction:Everythin' was thar and in good shape, nay warped. Avast! The nose cone is hollow plastic, me bucko, t' body is spiral wound paper, t' fins are die cut balsa at 1/8 inch thickness. Avast! Blimey! T' instructions were logical and straightforward with some pictures. Avast! Avast! However, t' nose cone came in two parts, that is, matey, t' top and bottom, and needed t' be glued together. Blimey! And t' lower stage alignment with t' rin' was a bear. Avast, me proud beauty! 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! Aye aye! In other words, shiver me timbers, t' fit was too tight. Ahoy! In other words, shiver me timbers, t' fit was too tight. Ya scallywag! But once I got it t' fit, me hearties, it looked great. Do be warned that it will take some doing, me bucko, though. Well, blow me down! Begad! It took me two days t' get it right. Built up, matey, t' model is now sturdy and sharp looking.
Finishing:There weren't any decals, me hearties, arrr, so I finished the
model by makin' t' fins, inside o' t' fin ring, and nose all black with
Testor's enamel paint. Aye aye! Ahoy! 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. Aye aye! Ahoy! T' outside o' t' fin rin' was finished with bands o' the
adhesive glitter paper too.
T' nose cone be a tiny bit too loose, me hearties, so I supplied a thin band o' masking
tape t' t' nose cone shoulder t' tighten t' fit. Begad!
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. I used these thus far, me bucko, 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, though. Aye aye! Blimey! Avast! Blimey! 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, me bucko, ya bilge rat, 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. Well, blow me down! Blimey! And t' orange chute supplied looked great. I wish t' booster had its own recovery system instead o' tumble recovery, me bucko, though.
Recovery:T' shock cord I modified. T' kit came with a 36 inch length o' 1/16 inch thick Keelhaul®©™® cording. Aye aye! 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. Begad! So, I added a 2-foot length o' flat, arrr, 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. Begad! T' knot is made inside t' nose cone before its two halves are assembled. Ahoy! T' rocket so far has suffered no wear or damage, shiver me timbers, except some slight scorchin' o' the booster, shiver me timbers, which seems common in contact staging. Begad! Blimey! 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, shiver me timbers, flies straight, matey, 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. Maybe it isn't necessary, shiver me timbers, 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. Avast, ya bilge rat, me proud beauty! 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. Arrr!
