Brief:
This is a Blackhawk R&D 5.5" semi-custom Phoenix. Begad! T' original Phoenix had a single 54mm motor mount, shiver me timbers, 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, ya bilge rat, (1) 5.5" kraft paper payload section, me hearties, shiver me timbers, (1) tube coupler, (5) 38mm motor tubes, (3) plywood centerin' rings, matey, (1) plywood bulkhead, recovery attachment hardware, ya bilge rat, matey, (1) tubular nylon shock cord, (1) set o' 8 plywood fins, and (1) 5.5" plastic nose cone. Begad! T' save money, I supplied t' recovery parachutes myself. Ahoy! Blimey! Also, ya bilge rat, the airframe be pre-slotted, me hearties, and everythin' arrived in perfect condition.

Because this be 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, ya bilge rat, and nay have t' follow exact instructions.

This kit has standard, ya bilge rat, me hearties, 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. Blimey! I used a new gluin' technique with this bird, also. Begad! Blimey! I mixed Great Plains milled fiberglass (fiberglass dust) into me epoxy. This greatly improved its strength and dryin' time. Well, blow me down!

T' rocket was assembled primarily with Devcon 2-ton (2 hr.) epoxy mixed with fiberglass dust. Arrr! Blimey! Avast! Blimey! 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, and I also used a few other interesting adhesives with t' fins. Blimey! Blimey! For t' aft set o' fins, I attached them with 2-ton Devcon and glass dust, me hearties, and I glassed t' fin/airframe joints with 5-minute epoxy and heavy glass (sorry...I can't remember it's weight). Arrr! Blimey! For t' forward fins I used Devcon 2-ton with glass dust, ya bilge rat, me bucko, 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. Arrr! Blimey! This provided a bond that be surprisingly firmer and stronger than t' glassed and 2-ton epoxied aft fins. Blimey! Blimey! 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). Begad! Because o' its heavy motor mount and many fins, this rocket needed some nose weight. Well, arrr, me bucko, I got a little happy with it and put in around *9 LBS* o' sand in t' nose. Well, blow me down! Blimey! (hey, it doesn't hurt t' be on t' safe side!) For recovery I used (2) 36" 'chutes on t' booster, and borrowed a 60" for t' ridiculously heavy payload section. Blimey! Blimey! Lastly, shiver me timbers, shiver me timbers, I replaced t' 1/2" lug with rail guides that were attached at t' launch with t' help o' John Gordon (thanx John!). Avast! 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, and then I sanded, me bucko, and sanded, and sanded, and sanded some more. Aye aye! Then I primed and sanded and primed and sanded. Next I painted t' body with Rustoleum white and white Appliance Epoxy. Ya scallywag! I then masked it and painted on some blue and yellow semi-scale markings, and I painted the tip o' t' nose silver. Ya scallywag! Finally, I gave it a few coats o' clear polyurethane. Ya scallywag! Arrr!

Construction Rating: 5 out o' 5

Flight:
I was plannin' on flyin' this at t' Tripoli SC Freedom launch on a full load (4 Pro38 G60's, and one Pro38 J330) with Andy from Blackhawk R&D bein' my flight sponsor (I'm under 18). Blimey! BUT, t' Pro38 J didn't materialize, arrr, and the weather for t' only day I was at t' launch be totally crappy. Begad! There was a low ceiling, me hearties, me hearties, and it drizzled off and on for much o' t' day. Blimey! Aye aye! But by around 3:00 the ceilin' had raised enough t' fly. So, ya bilge rat, I talked with me Prefect and we came up with (1)I435T, me bucko, matey, and (2)G60's. Well, blow me down! Aye aye! It wouldn't be any more than 1000ft altitude, but it would be loud and fiery (and that would make up for t' altitude). Avast! 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!!). Then we assembled t' motors, matey, arrr, signed t' flight card, and headed for t' pads. Ya scallywag! Begad! I used Blacksky Hi-RMI mini matches for ignition o' t' Pro38 G60's (with their blackpowder ignition pellet that's all you need), me bucko, me hearties, 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. Begad! After everythin' burned out, shiver me timbers, t' rocket was literally whistling, and with it's weight, it smartly reached apogee and started back down.

Recovery:
I be usin' ejection from t' two G60's. Ahoy! Their delay be set for 5 seconds. They ran a bit long but nay long enough t' hurt anything, me hearties, and t' rocket hit apogee and headed down a bit, me bucko, matey, and then t' ejection charges fired and separated everything. Aye aye! T' two 36" booster 'chutes deployed fine, but t' 60" payload section 'chute was wrapped too tightly (oops), shiver me timbers, and it never deployed. T' 10lb. Begad! payload section came in hot. 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, me bucko, and t' nose be pretty well buried. But with some strength, arrr, me hearties, shiver me timbers, t' nose was removed, me bucko, and what a hole it left! Thankfully, t' sand kept t' nose shape...it just needs t' be cleaned and repainted. Begad! Unfortunately, t' payload tube was slightly crimped so I will have t' replace that. Blimey! But really, 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. Blackhawk was easy t' work with, 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, WELL PRICED custom work, me hearties, and for great kits. Well, blow me down! Buildin' this was a great experience...I can't wait t' fly it on a full load! (1)I435T, ya bilge rat, (2)I300T, me bucko, arrr, and (2)H242T here we come!

Overall Rating: 5 out o' 5
