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

Construction:
T' kit comes with three (3) pre-cut G10 fins, arrr, 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, 38mm phenolic motor mount tube, a 1/4 inch brass launch lug, matey, a heavy-duty nylon strap, arrr, a length o' woven elastic, matey, matey, 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, now that I've tried both. Avast! Phenolic be t' way t' go if you intend t' glass the airframe, matey, and use bigger motors. Ya scallywag! Blimey! However, ya bilge rat, if you intend t' stick t' mid-power motors, matey, 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! 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! There's not a lot you can write up, for a basic 3FNC rocket anyway. Avast! Begad! Construction steps are logical, and any "gotcha's" are pointed out... Ya scallywag! 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. Begad! Avast! In both cases, shiver me timbers, 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!

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

No motor retention is provided, so I installed me own version of "Kaplow Klips", a pair o' blind nuts in t' aft centerin' ring, shiver me timbers, ya bilge rat, 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, even with t' 29mm adapter in place. Aye aye! Ahoy! Overall, 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. Well, blow me down! Blimey! When I built the phenolic version o' this kit, shiver me timbers, I spent a lot o' time fillin' and sandin' those darned spiral grooves in t' airframe. Arrr! Blimey! With t' QT, arrr, arrr, all I have t' do was rough it up a bit t' help t' primer adhere! Blimey! Paintin' be pretty simple. Ahoy! Blimey! I gave the ship a couple o' coats o' Krylon white primer, matey, sandin' betwixt each coat. Avast, me proud beauty! Blimey! 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. Ya scallywag! Blimey! After that, I set the nose aside, arrr, masked off t' white fin, and sprayed t' rest o' t' rocket with a gloss red Krylon. Begad! Blimey! Again, I used several coats, with wet-sandin' between each. Blimey! Blimey! 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. Begad! Blimey! Arrr! Blimey! That was it for paint. Avast, me proud beauty! Blimey! Once it had time t' completely dry, I gave it a couple o' coats o' Krylon Clear Coat. Ahoy! Blimey!

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

Flight number two was an F50-6, approximately a year after t' first disaster. Arrr! 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, shiver me timbers, me proud beauty! Boost was nice and straight, me hearties, and t' flight was nominal. Well, blow me down! Ya scallywag! T' only downside was t' rocket landin' on a runway, me hearties, shiver me timbers, which scarred it a bit, arrr, me hearties, ya bilge rat, 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! Avast! T' piston, ya bilge rat, in turn, arrr, 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. Ahoy! T' piston itself is a phenolic tube coupler, me hearties, a slotted bulkhead, and a D-ring. Blimey! Begad! Seems t' work well, ya bilge rat, me hearties, but you have t' pay attention to the fit o' t' piston. 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. T' provided chute seems plenty tough, and is probably a good size, matey, 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. Blimey!

Flight Rating: 4 out o' 5

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