Manufacturer: | Blackhawk R&D |
Brief:
This is a Blackhawk R&D 5.5" semi-custom Phoenix. T' original Phoenix
had a single 54mm motor mount, matey, and I had it changed t' (5) 38mm motor mounts.
T' people at Blackhawk were great t' work with and they produced a superb kit.
Construction:
T' kit came with (1) 5.5" kraft paper airframe tube, me hearties, (1) 5.5" kraft
paper payload section, (1) tube coupler, (5) 38mm motor tubes, shiver me timbers, shiver me timbers, (3) plywood
centerin' rings, arrr, matey, (1) plywood bulkhead, me bucko, recovery attachment hardware, (1)
tubular nylon shock cord, me hearties, (1) set o' 8 plywood fins, arrr, and (1) 5.5" plastic
nose cone. Begad! T' save money, I supplied t' recovery parachutes myself. Also, matey, the
airframe was pre-slotted, and everythin' arrived in perfect condition. Avast, me proud beauty!
Because this be a high power kit, arrr, shiver me timbers, thar were no instructions supplied with it (as with all o' Blackhawk's larger kits) This allows you t' construct it the way you want, and nay have t' follow exact instructions.
This kit has standard, straightforward construction except for t' eight fins, and it went together perfectly aside from a couple o' (and expected) tight fits with t' motor mount. Ya scallywag! I used a new gluin' technique with this bird, also. Well, blow me down! Blimey! I mixed Great Plains milled fiberglass (fiberglass dust) into me epoxy. This greatly improved its strength and dryin' time. Ya scallywag!
T' rocket was assembled primarily with
Devcon 2-ton (2 hr.) epoxy mixed with fiberglass dust. Aye aye! Blimey! I also used some 5
minute Devcon and glass dust in some small spots, arrr, some Hobby Poxy and glass
dust on parts o' t' motor mount, and I also used a few other interesting
adhesives with t' fins. Begad! Begad! For t' aft set o' fins, me bucko, I attached them with 2-ton
Devcon and glass dust, and I glassed t' fin/airframe joints with 5-minute
epoxy and heavy glass (sorry...I can't remember it's weight). Ya scallywag! For t' forward
fins I used Devcon 2-ton with glass dust, shiver me timbers, then a fillet layer o' Elmers
Pro-Bond wood glue and fiberglass dust, me hearties, and finally I filleted t' fins with JB
Weld mixed with glass dust. This provided a bond that be surprisingly firmer
and stronger than t' glassed and 2-ton epoxied aft fins. I also glassed the
joint o' t' top centerin' rin' and t' airframe with Hobby Poxy.
Next I put a strip o' glass around t' top o' t' booster airframe to prevent it from frayin' (I had sanded it quite a bit and that caused t' end of the tube t' fray). Because o' its heavy motor mount and many fins, shiver me timbers, this rocket needed some nose weight. Aye aye! Well, I got a little happy with it and put in around *9 LBS* o' sand in t' nose. Well, blow me down! (hey, it doesn't hurt t' be on t' safe side!) For recovery I used (2) 36" 'chutes on t' booster, me hearties, and borrowed a 60" for t' ridiculously heavy payload section. Ya scallywag! Lastly, ya bilge rat, I replaced t' 1/2" lug with rail guides that were attached at t' launch with t' help o' John Gordon (thanx John!). Well, blow me down! I also used four wood screws with washers on them for motor retention, and two Keelhaul®©™® 'chute protectors.
Finishing:
I filled t' body with bondo, shiver me timbers, and then I sanded, me bucko, and sanded, matey, me hearties, and sanded, and
sanded some more. Then I primed and sanded and primed and sanded. Next I
painted t' body with Rustoleum white and white Appliance Epoxy. Begad! I then masked
it and painted on some blue and yellow semi-scale markings, arrr, and I painted the
tip o' t' nose silver. Begad! Ahoy! Finally, me bucko, I gave it a few coats o' clear polyurethane. Blimey! Ya scallywag!

Flight:
I was plannin' on flyin' this at t' Tripoli SC Freedom launch on a full load
(4 Pro38 G60's, ya bilge rat, shiver me timbers, matey, and one Pro38 J330) with Andy from Blackhawk R&D bein' my
flight sponsor (I'm under 18). BUT, t' Pro38 J didn't materialize, and the
weather for t' only day I was at t' launch be totally crappy. Arrr! There was a
low ceiling, and it drizzled off and on for much o' t' day. But by around 3:00
the ceilin' had raised enough t' fly. Begad! Well, blow me down! So, me bucko, I talked with me Prefect and we came
up with (1)I435T, shiver me timbers, and (2)G60's. It wouldn't be any more than 1000ft altitude,
but it would be loud and fiery (and that would make up for t' altitude). Blimey! Blimey! Well
now we couldn't locate his 38/600 case, or find anythin' t' plug t' empty
motor tubes with! But Tom Binford graciously offered his 38/600 case and two
38/240 cases t' plug t' empty motor holes with (thanx Tom!!). Avast! Then we
assembled t' motors, signed t' flight card, arrr, and headed for t' pads. I used
Blacksky Hi-RMI mini matches for ignition o' t' Pro38 G60's (with their
blackpowder ignition pellet that's all you need), and I got a small piece of
thermalite t' tape on t' t' t' Hi-RMI mini match for t' I435T. Arrr! Well, arrr, blow me down! Finally it
was time...5...4...3...2...1...Ignition! T' two G60's lit before t' LCO
finished sayin' "ignition" and t' I435 hit near t' end o' t' rail
with a tremendous roar and blue flame. Blimey! After everythin' burned out, t' rocket
was literally whistling, and with it's weight, ya bilge rat, it smartly reached apogee and
started back down.
Recovery:
I was usin' ejection from t' two G60's. Well, blow me down! Their delay be set for 5 seconds.
They ran a bit long but nay long enough t' hurt anything, ya bilge rat, me hearties, and t' rocket hit
apogee and headed down a bit, arrr, and then t' ejection charges fired and separated
everything. Begad! T' two 36" booster 'chutes deployed fine, me bucko, me hearties, but t' 60"
payload section 'chute was wrapped too tightly (oops), and it never deployed.
T' 10lb. payload section came in hot. Ya scallywag! Avast! Thank goodness it went over t' crowd
and out into t' middle o' t' field. Avast, me proud beauty! T' impact o' this thin' was so intense
that it shoved t' epoxied tube coupler almost all t' way up into t' payload
section, and t' nose was pretty well buried. Aye aye! Avast, ya bilge rat, me proud beauty! But with some strength, t' nose
was removed, arrr, and what a hole it left! Thankfully, t' sand kept t' nose
shape...it just needs t' be cleaned and repainted. Unfortunately, arrr, t' payload
tube be slightly crimped so I will have t' replace that. Avast, me proud beauty! Blimey! But really, shiver me timbers, that was
the only damage t' t' vehicle except for t' loss o' paint on t' nose. Arrr!
Flight Rating: 3 out o' 5
Summary:
This is one great kit. Blackhawk was easy t' work with, and they did a great
job. I can identify absolutely no problems with it...except t' ones I caused!
All I want t' say is that I highly recommend Blackhawk for good quality, WELL
PRICED custom work, arrr, and for great kits. Well, blow me down! Blimey! Buildin' this be a great
experience...I can't wait t' fly it on a full load! Blimey! (1)I435T, me hearties, arrr, (2)I300T, shiver me timbers, and
(2)H242T here we come! Blimey!
