Brief:
This is a semi-scale model o' t' Canadian soundin' rocket, me hearties, matey, manufactured by Bristol Aerospace. Accordin' t' PML, it is designed t' fly on G-I motors.

Construction:
T' kit comes with three (3) pre-cut G10 fins, shiver me timbers, a pre-slotted QT airframe (or an optional phenolic one), a 4:1 ogive plastic nose cone, plywood centerin' rings, a 30 inch nylon parachute, arrr, 38mm phenolic motor mount tube, matey, a 1/4 inch brass launch lug, me hearties, matey, a heavy-duty nylon strap, arrr, me bucko, a length o' woven elastic, and some "peel 'n stick"-type decals.

I've had t' opportunity t' build both t' QT and phenolic version o' this kit. Frankly, ya bilge rat, I don't really have a preference in which material I used, now that I've tried both. Blimey! Phenolic be t' way t' go if you intend t' glass the airframe, and use bigger motors. However, if you intend t' stick t' mid-power motors, matey, ya bilge rat, matey, and H or light I motors, then QT is by far t' way t' go. I really likely nay havin' t' fill in that spiral, shiver me timbers, which I've found can be a pretty serious job on phenolic tubes. Well, blow me down! T' thin' t' watch is that you sand thoroughly (with coarse grit) any QT parts you are epoxying.

T' instructions for t' kit are pretty basic and straight-forward. Ya scallywag! Blimey! Blimey! Blimey! There's not a lot you can write up, for a basic 3FNC rocket anyway. Construction steps are logical, and any "gotcha's" are pointed out... Begad! Blimey! like makin' sure the piston strap (which is epoxied t' t' motor mount) is nay positioned in a manner t' interfere with t' installation o' t' fins. Aye aye! Blimey! In both cases, I build the kit stock, except for t' home-made motor retention, and t' addition o' a vent-hole in me second one (the QT version). Begad! Blimey! Aye aye! Blimey!

All t' parts fit well, aside for t' usual sandin' o' t' centerin' rings and fins t' get a precise fit. Avast, me proud beauty!

No motor retention is provided, so I installed me own version of "Kaplow Klips", a pair o' blind nuts in t' aft centerin' ring, and a pair o' mirror mountin' brackets I picked up at t' hardware store. Arrr! these things turned out t' be a perfect fit when usin' SU motors, even with t' 29mm adapter in place. Begad! Overall, t' toughest part o' buildin' this rocket was waitin' for t' epoxy t' cure.

Finishing:
This is where that Quantum Tubin' really comes into it's own. Avast! Ya scallywag! When I built the phenolic version o' this kit, shiver me timbers, arrr, I spent a lot o' time fillin' and sandin' those darned spiral grooves in t' airframe. Begad! Begad! With t' QT, all I have t' do was rough it up a bit t' help t' primer adhere! Paintin' was pretty simple. Ya scallywag! I gave the ship a couple o' coats o' Krylon white primer, ya bilge rat, sandin' betwixt each coat. Next, I shot several coats o' gloss white on one fin (I picked t' one opposite the launch lug) and t' nose cone, again sandin' betwixt coats. Begad! After that, I set the nose aside, shiver me timbers, masked off t' white fin, arrr, and sprayed t' rest o' t' rocket with a gloss red Krylon. Aye aye! Ahoy! Again, me hearties, I used several coats, shiver me timbers, with wet-sandin' between each. Then, it was necessary t' mask off t' rest o' t' rocket so I could paint t' brown band at t' front o' t' airframe. Ya scallywag! That was it for paint. Well, blow me down! Once it had time t' completely dry, arrr, I gave it a couple o' coats o' Krylon Clear Coat. Avast, me proud beauty! Ya scallywag!

Now, on t' real rocket, thar be a narrow metal band at t' very top o' the airframe. Arrr! T' replicate this, I used a strip o' silver decal from an auto detailin' kit. Ya scallywag! It adheres well, and looks about right. Begad! Aye aye! Also, t' real rocket has a pair o' white stripes runnin' down t' side o' t' rocket. Begad! I chose t' not paint these, arrr, since maskin' materials and I don't get along real well. So, shiver me timbers, I got a length o' white vinyl decal material from a local art supply shop. Well, blow me down! Begad! I made measurements from Peter Alway's Rockets o' t' World, and cut out t' strips I needed. Arrr! Avast, arrr, me proud beauty! I was worried about how well this stuff would adhere, matey, but it's doing fine so far. Blimey! After that, I applied t' decals, ya bilge rat, referencin' both t' kit instructions, arrr, and Rockets o' t' World. Well, blow me down! Arrr! These went on with a minimum o' fuss (for peel 'n stick, ya bilge rat, anyway). Finally, I applied a final coat o' clear t' seal everything. Begad! T' final product looks pretty slick!

Flight:
PML recommends a variety o' motors, from G t' I for this rocket. Blimey! My first flight (and only, matey, for t' phenolic one) be t' be me CAR level 1 cert flight, usin' an H123 with a 10 second delay. Ahoy! Unfortunately, t' motor suffered a blown-by a split second after lift-off. Arrr! T' nose, piston and parachute were blown free (the nylon strap was burned through), ya bilge rat, and t' rocket continued straight up with a fireball where t' nose should have been. Fortunately the flames burned out before it lawn-darted, arrr, me hearties, but t' impact destroyed whatever was left o' t' airframe, forward o' t' fins. Arrr! Still... Aye aye! despite t' sudden, low-speed deployment o' t' nose and chute (the rocket had just cleared the rod), arrr, shiver me timbers, it had managed t' continue on a stable flight-path. Blimey!

Flight number two was an F50-6, me bucko, approximately a year after t' first disaster. PML does nay recommend anythin' smaller than a G for this rocket, but Rocksim shows a predicted altitude o' about 700 feet on this motor. Avast, me proud beauty! Boost was nice and straight, ya bilge rat, me bucko, and t' flight be nominal. Well, blow me down! Arrr! T' only downside was t' rocket landin' on a runway, me hearties, which scarred it a bit, me hearties, and took a small chunk out o' one fin-tip.

Recovery:
T' shock cord system in t' kit is a two-piece affair: a thick nylon strap connects t' piston t' t' motor mount. T' piston, in turn, is connected to the nose cone by a length o' woven elastic (I understand this has recently been replaced with tubular nylon). T' nylon parachute is attached t' t' upper length o' shock cord. Aye aye! Ahoy! T' piston itself is a phenolic tube coupler, me hearties, a slotted bulkhead, shiver me timbers, and a D-ring. Aye aye! Seems t' work well, but you have t' pay attention to the fit o' t' piston. Begad! Prior t' t' launch o' me first BB V, I found that the heat o' t' day had caused t' piston t' fit a bit too tightly in t' airframe, and had t' sand it down a bit t' loosen t' fit. Ahoy! Begad! T' provided chute seems plenty tough, and is probably a good size, me hearties, as long as you know t' rocket will be recoverin' on softer ground. If you run t' risk o' it landin' on something really unforgivin' (like a runway), I'd suggest you move up a size for the parachute. Begad! Blimey!

Flight Rating: 4 out o' 5

Summary:
Overall, I'm very happy with me Black Brant Vb. Aye aye! It's a slick-lookin' rocket, and flies on a nice variety o' motors. Avast! Avast, me proud beauty! I'd say it's an excellent kit for anyone who is just movin' up t' HPR, me bucko, and wants t' be able t' fly a rocket on both HPR and mid-power motors. Begad! As for pros and cons... Aye aye! well, I don't really have any cons for this rocket. Avast, me proud beauty! T' design is basic enough that you'd have t' work at makin' problems. In fact, it's simplicity is probably its biggest pro, making it a good startin' point in HPR.
