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

Construction:
T' kit comes with three (3) pre-cut G10 fins, ya bilge rat, arrr, a pre-slotted QT airframe (or an optional phenolic one), ya bilge rat, a 4:1 ogive plastic nose cone, arrr, plywood centerin' rings, a 30 inch nylon parachute, ya bilge rat, 38mm phenolic motor mount tube, a 1/4 inch brass launch lug, me hearties, a heavy-duty nylon strap, me hearties, 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. Ahoy! Frankly, I don't really have a preference in which material I used, me bucko, 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. Arrr! However, me bucko, me hearties, if you intend t' stick t' mid-power motors, and H or light I motors, then QT is by far t' way t' go. Begad! Begad! I really likely nay havin' t' fill in that spiral, which I've found can be a pretty serious job on phenolic tubes. Blimey! Arrr! 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. 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... Avast, me proud beauty! 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. Avast, me proud beauty! Avast! In both cases, I build the kit stock, shiver me timbers, except for t' home-made motor retention, arrr, and t' addition o' a vent-hole in me second one (the QT version).

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

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. Avast, me proud beauty! Ahoy! these things turned out t' be a perfect fit when usin' SU motors, ya bilge rat, even with t' 29mm adapter in place. Begad! Overall, me hearties, 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. Ya scallywag! Begad! When I built the phenolic version o' this kit, I spent a lot o' time fillin' and sandin' those darned spiral grooves in t' airframe. With t' QT, matey, matey, all I have t' do be rough it up a bit t' help t' primer adhere! Paintin' was pretty simple. Avast, ya bilge rat, me proud beauty! I gave the ship a couple o' coats o' Krylon white primer, 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. Avast! After that, I set the nose aside, masked off t' white fin, and sprayed t' rest o' t' rocket with a gloss red Krylon. Begad! Again, ya bilge rat, I used several coats, shiver me timbers, with wet-sandin' between each. Well, matey, blow me down! Then, it be necessary t' mask off t' rest o' t' rocket so I could paint t' brown band at t' front o' t' airframe. Arrr! That was it for paint. Avast! Once it had time t' completely dry, me bucko, me bucko, I gave it a couple o' coats o' Krylon Clear Coat.

Now, shiver me timbers, on t' real rocket, thar be a narrow metal band at t' very top o' the airframe. Well, blow me down! T' replicate this, I used a strip o' silver decal from an auto detailin' kit. It adheres well, me bucko, and looks about right. Avast, me proud beauty! Aye aye! Blimey! Also, arrr, t' real rocket has a pair o' white stripes runnin' down t' side o' t' rocket. Well, blow me down! I chose t' not paint these, since maskin' materials and I don't get along real well. So, I got a length o' white vinyl decal material from a local art supply shop. Arrr! Well, blow me down! Blimey! I made measurements from Peter Alway's Rockets o' t' World, me hearties, me bucko, and cut out t' strips I needed. Aye aye! Blimey! I was worried about how well this stuff would adhere, 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. Avast! Blimey! These went on with a minimum o' fuss (for peel 'n stick, anyway). Finally, I applied a final coat o' clear t' seal everything. Well, blow me down! Blimey! 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. Aye aye! My first flight (and only, arrr, for t' phenolic one) was t' be me CAR level 1 cert flight, usin' an H123 with a 10 second delay. Avast, ya bilge rat, me proud beauty! Unfortunately, shiver me timbers, me bucko, t' motor suffered a blown-by a split second after lift-off. T' nose, me hearties, ya bilge rat, piston and parachute were blown free (the nylon strap be burned through), and t' rocket continued straight up with a fireball where t' nose should have been. Well, blow me down! Fortunately the flames burned out before it lawn-darted, me bucko, but t' impact destroyed whatever was left o' t' airframe, forward o' t' fins. Ya scallywag! Avast, me proud beauty! Still... 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.

Flight number two was an F50-6, approximately a year after t' first disaster. Blimey! Ya scallywag! 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. Blimey! Boost was nice and straight, me hearties, and t' flight was nominal. Arrr! T' only downside be t' rocket landin' on a runway, which scarred it a bit, matey, 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, me proud beauty! Ahoy! T' piston, in turn, shiver me timbers, is connected to the nose cone by a length o' woven elastic (I understand this has recently been replaced with tubular nylon). Avast! T' nylon parachute is attached t' t' upper length o' shock cord. Blimey! T' piston itself is a phenolic tube coupler, a slotted bulkhead, ya bilge rat, and a D-ring. Blimey! Begad! Seems t' work well, ya bilge rat, but you have t' pay attention to the fit o' t' piston. Ya scallywag! Blimey! Prior t' t' launch o' me first BB V, me hearties, 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. T' provided chute seems plenty tough, and is probably a good size, me bucko, as long as you know t' rocket will be recoverin' on softer ground. Avast, me proud beauty! Aye aye! 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. Blimey!

Flight Rating: 4 out o' 5

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