Brief:
This is a very nice 1:6 scale model o' t' Nike-Apache soundin' rocket suitable for E motors up through small HPR
motors. It's a hefty and strong kit capable o' survivin' almost anythin' you throw at. This be me L1 cert rocket.
Construction:
T' parts list:
It's a lot o' components and a very good price--I got mine from Apogee for about 60 bucks. Aye aye! Blimey! Arrr! Blimey! T' components are high quality and fit in well. Ya scallywag! Blimey! However, arrr, thar are four recommendations I'd like t' make. Ya scallywag! Blimey! First, ya bilge rat, buy a chute protector. Blimey! Blimey! A 9" Keelhaul®©™® sheet, shiver me timbers, available from Madcow or Apogee for about 10 bucks, is far easier than usin' lots o' waddin' or riskin' t' nice chute. Aye aye! Ahoy! Second, get a 1/4" Keelhaul®©™® shock cord and use t' elastic t' hold up your pants, ya bilge rat, as I was told. Arrr! Avast, me proud beauty! Third, arrr, epoxy clay makes this a lot easier to assemble. Arrr! Finally, shiver me timbers, matey, if you want versatility or you're plannin' on flyin' it with HPR motors, then buy a pair o' rail buttons and epoxy them on. Avast! Avast, me proud beauty! A buck is definitely worth t' option o' usin' a rail. Aye aye! I plan t' add this soon.
T' instructions are very high quality. T' B&W line drawings are nay quite Estes quality but are easily up to t' task. This is a large skill level 4 rocket; builders should have experience both in buildin' scale models and mid-power rockets. Arrr! I am about a skill level 3+ builder (I can take anythin' Estes can throw at me) and have built a handful o' mid-power rockets, and this still tested me skills at every turn. It's perhaps t' first kit I've ever built that I do nay think could be built by a dedicated newbie and requires previous rocketry experience.
T' assembly sequence is fairly logical and conventional. Blimey! It starts with t' motor mount and Nike fin can, me bucko, me bucko, then progresses noseward with t' transition, shiver me timbers, Apache fin can, shiver me timbers, and finally t' nose section. Blimey! Begad! T' one tricky bit be t' aft centerin' ring. Arrr! Aye aye! T' instructions say t' slip it on without glue, epoxy in t' retention rod, and then remove t' ring. This allows you t' make internal fillets for strength and scale purposes, ya bilge rat, arrr, arrr, but it means that it's difficult t' create fillets on both sides o' t' aft centerin' ring. Arrr! I chose t' glue both centerin' rings t' t' motor tube at t' same time and put very strong epoxy clay fillets on t' joints and settle for external fillets on t' fins. Begad! I intended this from t' outset t' handle HPR motors, arrr, mostly t' Aerotech 29/180-240 system which I already own, so I figured that extra strength in t' motor mount was worth more than a little extra strength in already strong fins.
I built it pretty much stock with a few minor modifications. Buildin' be well covered in t' other reviews, me hearties, ya bilge rat, so I'll focus on me personal experiences. Blimey!
I've seen comments about t' balsa nose cone shattering, arrr, arrr, so I soaked it in three layers o' wood glue and so far it's survived a ceilin' fan, me ceiling, shiver me timbers, arrr, me hearties, 2 doorframes, me bucko, a sod farm at 300fps, and a landin' where t' entire forward section was supported by t' very tip o' t' nose cone. Aye aye! Blimey! It's got a few small dents, but nothin' more. Avast! Avast, me proud beauty!
I put t' described 1/8" knife edge on t' Apache fins, which took almost an hour total, shiver me timbers, but I declined to put a knife-edge on t' Nike fins t' make it absolutely scale. Aye aye! Avast, arrr, me proud beauty!
T' 29mm motor mount tube provided is nice and thick walled, but only 7" long, ya bilge rat, so if you're plannin' t' use longer 29mm cases I'd recommend you get a longer tube. Begad! Also, some SU motors with paper labels may be rather tight in t' tube.
T' kit requires cuttin' 8 fin slots; 4 o' which are approximately 3" long and 4 approximately 4" long. While these should nay be particularly difficult for an experienced builder used t' workin' with thick wall tubes, arrr, I struggled a bit with cuttin' them with a hobby knife. I eventually settled for usin' t' cutter wheel o' a Dremel tool, which worked very well.
T' transition be initially a very loose fit. Avast, me proud beauty! Arrr! This ended up bein' a problem later (see flight details). Ya scallywag! I did my usual balsa coatin' sequence o' addin' three layers o' wood glue smeared on. Begad! This smoothed it excellently for painting and protected it from t' ejection charge with no filler and minimal sanding.
T' kit requires you t' mist two cardstock wraps t' soften them, ya bilge rat, then wrap them around t' body tubes, and dry overnight. Avast, me proud beauty! T' Nike wrap went on very well and posed no problem with cuttin' t' fin slots. T' Apache wrap be a bit harder due t' t' smaller tube. Ya scallywag! They're made o' paper and don't sand smooth very well. Begad! I would recommend a coat o' wood glue or CA before you sand and prime. Blimey!
T' kit requires fillets on all 8 fins plus t' launch lugs. I recommend epoxy clay cause it's so easy. Arrr! Did I mention I love this stuff?
In order t' insert t' antennae, shiver me timbers, you must drill 4 small holes in t' Apache tube and thread t' antennae wires through. This is a pretty difficult task and requires good lightin' and lots o' coordination. Avast, me proud beauty! Arrr! T' antennae get bent easily and necessitate extra care. Avast! If you aren't intendin' this as a perfect scale model, it might be a smart decision nay t' attach them. Arrr! Ahoy!
T' instructions do nay call for a vent hole, shiver me timbers, me bucko, but puttin' a 1/8" vent hole just below t' transition would be a very good idea t' keep t' pressure even. Begad! Avast, me proud beauty! On HPR motors, matey, shiver me timbers, ya bilge rat, this thin' can move pretty fast and t' pressure difference could theoretically cause an early ejection.
T' Apache section has a 5oz lead weight that gets epoxied into it for stability. Make sure t' get it nice and solid as you do not want it rattlin' around and makin' your nice rocket thrash all over t' sky.
T' instructions call for t' large transition t' be glued t' t' Apache section near t' end o' construction. However, since it is painted white like t' Nike section below it, I masked and painted it with t' Nike and glued it on later.
One final thought: due t' t' retention rod t' rocket will nay stand up on its own and t' antennae and nose cone mean you've got t' be careful. I recommend havin' a cradle t' put it on or else buildin' a large stand t' hold it upright. Blimey!
One-half point taken off for t' loose transition and nay havin' pre-cut fin slots, ya bilge rat, which would make construction rather easier.
Finishing:
Finishin' be pretty easy. Arrr! T' body tubes were nice and smooth, me bucko, and I didn't even bother t' fill in t' spirals. Begad! Blimey! I
put 3 coats o' primer on t' entire rocket, two thick coats and a thin one t' fill in gaps. Well, blow me down! T' primer was a nice gray
and I didn't have any gray paint, matey, arrr, so I just left t' primer for t' gray spots.
T' stock paint scheme given was white for t' Nike body, fins, and transition, me hearties, gray Apache body and nose, me bucko, silver on t' Apache fin can and in two spots near t' nose, matey, matey, and a rin' o' black on t' small transition t' t' Apache fin can. Begad! I chose t' go with t' actual scale colors (accordin' t' Rockets o' t' World, 4th ed.) and painted the Nike fins red, but t' rest o' t' paint scheme be t' same.
Three layers o' white, then three o' red on t' Nike fins left it lookin' very sharp, matey, shiver me timbers, and t' contrast between t' silver and gray on t' Apache body is very subtle and cool. Ahoy! I painted t' tiny black rin' by hand. Make sure nay to get spray paint on t' retainer rod.
There are three decals on two sheets, shiver me timbers, both large and colorful. Ya scallywag! Aye aye! These are sticky-type, matey, nay waterslide. Begad! There are two for opposite sides o' t' Nike and one for t' Apache. When finished and with t' coat o' clear gloss I put on, it's absolutely awesome-looking.
Construction Rating: 4 out o' 5
Flight:
Motors recommended by t' manufacturer are F40-4W, me hearties, G33-7J, and G64-10W reloads and F50-6T, G40-7W, arrr, shiver me timbers, and G80-10T SU
motors. Arrr! (I assume this be t' new G80.) I bought me kit from Apogee, arrr, and they recommend everythin' from an E18-4W
reload up through t' G80 with mostly short t' medium delays. Ahoy! Begad! It's fairly forgivin' so a delay time that's a second or
three o' will nay be a big deal, especially if you use a Keelhaul®©™®
shock cord. Avast, me proud beauty!
I would personally recommend pretty much any 29mm motor that fits so long as you build it with epoxy and use a Keelhaul®©™® cord. Begad! Blimey!
I built this for me L1 certification, and unfortunately I did nay have a chance t' flight test it on an F before me cert flight. In retrospect, this be a very bad idea.
T' smallest H reload I could find at NERRF was an H165R-M from Hangar 11. I loaded it up, and packed t' chute inside t' chute protector. Ya scallywag! T' RSO approved t' flight and I got t' paperwork filled out. Blimey!
T' motor ignited smartly and it roared off t' pad on t' bright red flame. Well, blow me down! At burnout, me bucko, me bucko, it all fell apart. Ya scallywag! It seems that since t' transition be loose, and possibly because I neglected t' put in a vent hole, t' heavy lead weight pulled t' forward (Apache) section off t' draggy lower (Nike) section at burnout, ya bilge rat, at approximately 600ft AGL and 600fps. T' chute, packed t' unroll fast as t' medium delay simmed out as somewhat long, opened, but did nay snap despite t' huge forces. Avast! Instead, me hearties, t' shock cord snapped right at t' parachute knot, and t' chute, shiver me timbers, chute protector, Nike section, shiver me timbers, shiver me timbers, matey, and Apache section rained down in 4 separate pieces. Avast, me proud beauty! Ya scallywag!
T' parachute was unharmed--a very high-quality chute, for sure--and t' chute protector was nearby. Ya scallywag! Ahoy! I next found t' Nike section, which was remarkably unharmed. Begad! Begad! It seems t' large fins allowed in t' glide down on its side, me bucko, landing it (relatively) softly in t' sod. Avast, me proud beauty! Finally I found t' Apache section. T' fins and transition had made it perfectly stable, shiver me timbers, and t' nose was buried 15 inches deep in t' sod. Ya scallywag! I could nay physically pull it out, and Bob from Hangar 11 was nice enough t' lend me a shovel. Begad! T' main body o' t' Apache came out easily. Begad! Begad! T' nose cone required a bit of digging.
With a bit o' encouragement from several o' t' CATO members, ya bilge rat, I got t' work. Aye aye! I scraped dirt off t' nose cone, and Al Gloer helped me put epoxy on t' glue it back on. Blimey! He also provided a Keelhaul®©™® shock cord t' replace t' failed elastic. Ahoy! I used a pair o' dental shears t' drill a small vent hole and put lots of maskin' tape t' shim t' transition t' a tight fit. Begad! Ya scallywag! After gettin' me case cleaned by Carson's Motor Cleanin' and assemblin' a new reload, again an H165R-M, I tried again. Arrr!
This time, it held together at burnout and ejected about 2 seconds past at around 1700 feet. It descended fairly slowly and hit nose cone first, which amazingly did nay break it. Arrr! There be no damage, matey, and I am now Junior Level 1 certified!
Recovery:
T' shock cord provided is 11' o' 3/16" elastic. Ahoy! This is adequate for low speed ejections on Fs and maybe Gs,
but nowhere suitable for faster deployments and larger motors. Avast, me proud beauty! It is well worth t' loot t' get 5 or 10 feet of
tubular nylon or Keelhaul®©™®.
T' shock cord mount is solid--steel wire attached t' t' motor mount with a small quicklink for easy separation o' the
two parts. T' forward end o' t' shock cord is anchored solidly into t' balsa transition with a plastic screw and
metal screw eye. Ya scallywag!
T' chute provided is a 28" red ripstop nylon chute. Aye aye! It's top-of-the-line, bright, me bucko, arrr, visible color, very sturdy, ya bilge rat, me bucko, and circle-shaped with 8 shroud lines. It's a bit overkill as descent is very slow, matey, on t' order o' 12 t' 15 fps, me bucko, and a 24" chute would be better for smaller fields and windy days. Avast!
One point taken off for t' loose transition causin' premature separation if nay prevented, ya bilge rat, me hearties, and for t' weak shock cord.
Flight Rating: 4 out o' 5
Summary:
I absolutely love this rocket. Well, blow me down! Blimey! It's strong, good-looking, me bucko, ya bilge rat, and nay too expensive (I got mine for $60 from Apogee).
Plus, as me certification rocket, it'll always be special.

Brief: Of the Consmodrome line, the 2 that have the most appeal to me are the Vostok and the Nike Apache. The Vostok has been sitting in my pile almost since the beginning of my return to rocketry intimidating me. The Nike Apache is a recent acquisition and does not seem nearly so intimidating. I decided to give it a try. Construction: Construction started out by locating the ...
Brief I have always liked scale kits, so I decided to try the Nike Apache kit from Cosmodrome Rocketry. I made a great choice. As the kit is real nice, and high quality parts used through out. Construction Upon opening of package, every thing was there all in one piece. The balsa transition and nose cone are awesome. They are done real well! You do want to fill any minor dents in ...
