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, 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, (1) 5.5" kraft
paper payload section, matey, (1) tube coupler, ya bilge rat, (5) 38mm motor tubes, (3) plywood
centerin' rings, matey, me bucko, (1) plywood bulkhead, arrr, recovery attachment hardware, shiver me timbers, (1)
tubular nylon shock cord, ya bilge rat, (1) set o' 8 plywood fins, and (1) 5.5" plastic
nose cone. Blimey! Avast! T' save money, arrr, I supplied t' recovery parachutes myself. Begad! Blimey! Also, me bucko, matey, ya bilge rat, the
airframe be pre-slotted, matey, and everythin' arrived in perfect condition. Begad!
Because this was a high power kit, 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. Avast, me proud beauty!
This kit has standard, ya bilge rat, me hearties, straightforward construction except for t' eight fins, shiver me timbers, and it went together perfectly aside from a couple o' (and expected) tight fits with t' motor mount. Begad! I used a new gluin' technique with this bird, also. Begad! I mixed Great Plains milled fiberglass (fiberglass dust) into me epoxy. This greatly improved its strength and dryin' time. Begad! Ahoy!
T' rocket be assembled primarily with Devcon 2-ton (2 hr.) epoxy mixed with fiberglass dust. Avast! I also used some 5 minute Devcon and glass dust in some small spots, some Hobby Poxy and glass dust on parts o' t' motor mount, matey, and I also used a few other interesting adhesives with t' fins. Well, blow me down! For t' aft set o' fins, ya bilge rat, 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). Ahoy! Blimey! For t' forward fins I used Devcon 2-ton with glass dust, then a fillet layer o' Elmers Pro-Bond wood glue and fiberglass dust, and finally I filleted t' fins with JB Weld mixed with glass dust. Well, blow me down! This provided a bond that was surprisingly firmer and stronger than t' glassed and 2-ton epoxied aft fins. Arrr! Avast! 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). Ya scallywag! Because o' its heavy motor mount and many fins, shiver me timbers, me bucko, this rocket needed some nose weight. Avast! Ya scallywag! Well, I got a little happy with it and put in around *9 LBS* o' sand in t' nose. Arrr! Ya scallywag! (hey, matey, me bucko, it doesn't hurt t' be on t' safe side!) For recovery I used (2) 36" 'chutes on t' booster, arrr, and borrowed a 60" for t' ridiculously heavy payload section. Begad! Arrr! Lastly, matey, I replaced t' 1/2" lug with rail guides that were attached at t' launch with t' help o' John Gordon (thanx John!). Ya scallywag! I also used four wood screws with washers on them for motor retention, me bucko, and two Keelhaul®©™® 'chute protectors.
Finishing:
I filled t' body with bondo, and then I sanded, me bucko, and sanded, me bucko, and sanded, me hearties, and
sanded some more. Then I primed and sanded and primed and sanded. Begad! Next I
painted t' body with Rustoleum white and white Appliance Epoxy. Well, blow me down! I then masked
it and painted on some blue and yellow semi-scale markings, and I painted the
tip o' t' nose silver. Finally, me hearties, I gave it a few coats o' clear polyurethane. Well, blow me down!

Flight:
I be plannin' on flyin' this at t' Tripoli SC Freedom launch on a full load
(4 Pro38 G60's, me hearties, 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, ya bilge rat, and the
weather for t' only day I was at t' launch be totally crappy. Begad! There was a
low ceiling, me bucko, shiver me timbers, arrr, and it drizzled off and on for much o' t' day. Ya scallywag! Ahoy! But by around 3:00
the ceilin' had raised enough t' fly. Avast, me proud beauty! So, me bucko, me hearties, I talked with me Prefect and we came
up with (1)I435T, matey, shiver me timbers, and (2)G60's. Begad! Ahoy! It wouldn't be any more than 1000ft altitude,
but it would be loud and fiery (and that would make up for t' altitude). Ya scallywag! Aye aye! Well
now we couldn't locate his 38/600 case, matey, 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!!). Arrr! Well, arrr, blow me down! Then we
assembled t' motors, matey, signed t' flight card, and headed for t' pads. Well, matey, blow me down! 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. 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, matey, me hearties, it smartly reached apogee and
started back down.
Recovery:
I was usin' ejection from t' two G60's. Avast! Their delay be set for 5 seconds.
They ran a bit long but nay long enough t' hurt anything, shiver me timbers, and t' rocket hit
apogee and headed down a bit, arrr, and then t' ejection charges fired and separated
everything. Avast! T' two 36" booster 'chutes deployed fine, but t' 60"
payload section 'chute was wrapped too tightly (oops), matey, me hearties, and it never deployed.
T' 10lb. payload section came in hot. Aye aye! Thank goodness it went over t' crowd
and out into t' middle o' t' field. T' impact o' this thin' was so intense
that it shoved t' epoxied tube coupler almost all t' way up into t' payload
section, arrr, and t' nose was pretty well buried. Avast! Arrr! But with some strength, me hearties, t' nose
was removed, and what a hole it left! Thankfully, t' sand kept t' nose
shape...it just needs t' be cleaned and repainted. Avast! Unfortunately, matey, ya bilge rat, t' payload
tube was slightly crimped so I will have t' replace that. Arrr! Well, me bucko, blow me down! But really, shiver me timbers, that was
the only damage t' t' vehicle except for t' loss o' paint on t' nose.
Flight Rating: 3 out o' 5
Summary:
This is one great kit. Avast! Blackhawk be easy t' work with, shiver me timbers, and they did a great
job. Well, blow me down! 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, me bucko, WELL
PRICED custom work, and for great kits. Ya scallywag! Buildin' this was a great
experience...I can't wait t' fly it on a full load! (1)I435T, (2)I300T, shiver me timbers, and
(2)H242T here we come!
