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

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

I've had t' opportunity t' build both t' QT and phenolic version o' this kit. Begad! Begad! Frankly, me hearties, I don't really have a preference in which material I used, now that I've tried both. Phenolic be t' way t' go if you intend t' glass the airframe, ya bilge rat, and use bigger motors. Well, blow me down! However, me hearties, if you intend t' stick t' mid-power motors, arrr, and H or light I motors, arrr, then QT is by far t' way t' go. Avast, me proud beauty! I really likely nay havin' t' fill in that spiral, shiver me timbers, shiver me timbers, which I've found can be a pretty serious job on phenolic tubes. 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. Blimey! Blimey! Begad! Blimey! There's not a lot you can write up, for a basic 3FNC rocket anyway. Well, blow me down! Blimey! Construction steps are logical, and any "gotcha's" are pointed out... Arrr! 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. 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! Arrr! 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", shiver me timbers, a pair o' blind nuts in t' aft centerin' ring, arrr, and a pair o' mirror mountin' brackets I picked up at t' hardware store. Well, blow me down! Arrr! these things turned out t' be a perfect fit when usin' SU motors, even with t' 29mm adapter in place. Overall, matey, me bucko, 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. When I built the phenolic version o' this kit, me hearties, I spent a lot o' time fillin' and sandin' those darned spiral grooves in t' airframe. With t' QT, all I have t' do be rough it up a bit t' help t' primer adhere! Blimey! Paintin' was pretty simple. Well, blow me down! Avast! Blimey! I gave the ship a couple o' coats o' Krylon white primer, matey, sandin' betwixt each coat. Arrr! Blimey! Next, I shot several coats o' gloss white on one fin (I picked t' one opposite the launch lug) and t' nose cone, me hearties, shiver me timbers, ya bilge rat, again sandin' betwixt coats. Avast! After that, I set the nose aside, me hearties, masked off t' white fin, me bucko, ya bilge rat, shiver me timbers, and sprayed t' rest o' t' rocket with a gloss red Krylon. Arrr! Ahoy! Blimey! Again, me bucko, matey, I used several coats, with wet-sandin' between each. Ahoy! Blimey! Then, me hearties, shiver me timbers, it was necessary t' mask off t' rest o' t' rocket so I could paint t' brown band at t' front o' t' airframe. Aye aye! That be it for paint. Once it had time t' completely dry, me hearties, I gave it a couple o' coats o' Krylon Clear Coat. Avast, me proud beauty!

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

Construction Rating: 4 out o' 5

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

Flight number two was an F50-6, approximately a year after t' first disaster. Well, blow me down! Aye aye! PML does nay recommend anythin' smaller than a G for this rocket, me bucko, but Rocksim shows a predicted altitude o' about 700 feet on this motor. Avast, me proud beauty! Blimey! Boost was nice and straight, matey, me hearties, and t' flight was nominal. Arrr! Begad! T' only downside was t' rocket landin' on a runway, which scarred it a bit, arrr, 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. Avast! 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). Avast, me proud beauty! Blimey! T' nylon parachute is attached t' t' upper length o' shock cord. Ahoy! Blimey! T' piston itself is a phenolic tube coupler, me bucko, ya bilge rat, a slotted bulkhead, matey, and a D-ring. Seems t' work well, me bucko, but you have t' pay attention to the fit o' t' piston. Begad! Aye aye! 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. Well, blow me down! Well, blow me down! T' provided chute seems plenty tough, and is probably a good size, me bucko, ya bilge rat, as long as you know t' rocket will be recoverin' on softer ground. Ya scallywag! 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. Avast!

Flight Rating: 4 out o' 5

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