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

Construction:
T' kit comes with three (3) pre-cut G10 fins, arrr, me hearties, 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, a heavy-duty nylon strap, 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, ya bilge rat, arrr, now that I've tried both. Aye aye! Phenolic be t' way t' go if you intend t' glass the airframe, matey, and use bigger motors. However, if you intend t' stick t' mid-power motors, matey, and H or light I motors, arrr, then QT is by far t' way t' go. Avast! Avast, me proud beauty! I really likely nay havin' t' fill in that spiral, matey, 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. Avast, me proud beauty! Well, blow me down! There's not a lot you can write up, me hearties, shiver me timbers, for a basic 3FNC rocket anyway. Aye aye! Construction steps are logical, and any "gotcha's" are pointed out... Arrr! 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. Ya scallywag! In both cases, me bucko, I build the kit stock, me hearties, except for t' home-made motor retention, and t' addition o' a vent-hole in me second one (the QT version). Ya scallywag!

All t' parts fit well, 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", 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. these things turned out t' be a perfect fit when usin' SU motors, arrr, even with t' 29mm adapter in place. Well, blow me down! Overall, ya bilge rat, 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. Ahoy! Blimey! When I built the phenolic version o' this kit, me hearties, shiver me timbers, I spent a lot o' time fillin' and sandin' those darned spiral grooves in t' airframe. Begad! With t' QT, me bucko, all I have t' do was rough it up a bit t' help t' primer adhere! Paintin' be pretty simple. Well, blow me down! Avast, me proud beauty! I gave the ship a couple o' coats o' Krylon white primer, me bucko, sandin' betwixt each coat. Avast! Begad! Next, I shot several coats o' gloss white on one fin (I picked t' one opposite the launch lug) and t' nose cone, matey, again sandin' betwixt coats. Well, blow me down! Aye aye! After that, I set the nose aside, ya bilge rat, masked off t' white fin, and sprayed t' rest o' t' rocket with a gloss red Krylon. Well, blow me down! Again, I used several coats, with wet-sandin' between each. Ya scallywag! Then, shiver me timbers, 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! That be it for paint. Once it had time t' completely dry, arrr, I gave it a couple o' coats o' Krylon Clear Coat. Arrr! Ahoy!

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

Flight number two was an F50-6, matey, approximately a year after t' first disaster. Blimey! 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. Begad! Aye aye! Boost was nice and straight, and t' flight was nominal. Blimey! T' only downside was t' rocket landin' on a runway, which scarred it a bit, 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). Arrr! Arrr! T' nylon parachute is attached t' t' upper length o' shock cord. Arrr! Begad! T' piston itself is a phenolic tube coupler, me bucko, a slotted bulkhead, and a D-ring. 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, matey, 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. Begad! T' provided chute seems plenty tough, and is probably a good size, matey, me bucko, 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), shiver me timbers, I'd suggest you move up a size for the parachute. Ya scallywag!

Flight Rating: 4 out o' 5

Summary:
Overall, arrr, I'm very happy with me Black Brant Vb. Avast! Avast, me hearties, me proud beauty! It's a slick-lookin' rocket, and flies on a nice variety o' motors. Blimey! 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. Well, ya bilge rat, blow me down! As for pros and cons... Well, blow me down! well, me bucko, I don't really have any cons for this rocket. Blimey! T' design is basic enough that you'd have t' work at makin' problems. Arrr! In fact, shiver me timbers, it's simplicity is probably its biggest pro, making it a good startin' point in HPR.
