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

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

All t' parts fit well, shiver me timbers, aside for t' usual sandin' o' t' centerin' rings and fins t' get a precise fit. Well, blow me down!

No motor retention is provided, so I installed me own version of "Kaplow Klips", me hearties, a pair o' blind nuts in t' aft centerin' ring, and a pair o' mirror mountin' brackets I picked up at t' hardware store. Well, blow me down! these things turned out t' be a perfect fit when usin' SU motors, me bucko, even with t' 29mm adapter in place. 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. 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. Blimey! Begad! With t' QT, all I have t' do be rough it up a bit t' help t' primer adhere! Paintin' was pretty simple. Well, blow me down! 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. Blimey! After that, arrr, I set the nose aside, masked off t' white fin, me bucko, shiver me timbers, me hearties, and sprayed t' rest o' t' rocket with a gloss red Krylon. Again, I used several coats, with wet-sandin' between each. Blimey! Then, arrr, it was necessary t' mask off t' rest o' t' rocket so I could paint t' brown band at t' front o' t' airframe. Well, blow me down! That be it for paint. Blimey! Begad! Once it had time t' completely dry, me hearties, I gave it a couple o' coats o' Krylon Clear Coat. Ahoy!

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

Flight:
PML recommends a variety o' motors, from G t' I for this rocket. Avast, matey, me proud beauty! 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. Begad! Unfortunately, matey, t' motor suffered a blown-by a split second after lift-off. Avast! T' nose, matey, ya bilge rat, piston and parachute were blown free (the nylon strap was burned through), matey, ya bilge rat, 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, but t' impact destroyed whatever was left o' t' airframe, me bucko, me bucko, forward o' t' fins. Still... Well, blow me down! 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. Ahoy!

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

Flight Rating: 4 out o' 5

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