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

Construction:
T' kit comes with three (3) pre-cut G10 fins, 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, shiver me timbers, 38mm phenolic motor mount tube, me bucko, me hearties, a 1/4 inch brass launch lug, me hearties, a heavy-duty nylon strap, ya bilge rat, a length o' woven elastic, shiver me timbers, 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. Aye aye! Frankly, me hearties, ya bilge rat, I don't really have a preference in which material I used, now that I've tried both. Ahoy! Blimey! Blimey! Phenolic be t' way t' go if you intend t' glass the airframe, and use bigger motors. Ya scallywag! Blimey! However, shiver me timbers, if you intend t' stick t' mid-power motors, ya bilge rat, matey, and H or light I motors, arrr, then QT is by far t' way t' go. Avast, me proud beauty! Blimey! 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! Ya scallywag! Blimey! 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! Avast, me proud beauty! 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... Well, me hearties, blow me down! 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. Aye aye! 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).

All t' parts fit well, aside for t' usual sandin' o' t' centerin' rings and fins t' get a precise fit. Avast! 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, me hearties, and a pair o' mirror mountin' brackets I picked up at t' hardware store. Begad! Avast! these things turned out t' be a perfect fit when usin' SU motors, arrr, even with t' 29mm adapter in place. Ya scallywag! 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. Begad! Arrr! 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. Begad! With t' QT, matey, shiver me timbers, all I have t' do was rough it up a bit t' help t' primer adhere! Paintin' be pretty simple. I gave the ship a couple o' coats o' Krylon white primer, shiver me timbers, sandin' betwixt each coat. Begad! Next, I shot several coats o' gloss white on one fin (I picked t' one opposite the launch lug) and t' nose cone, me bucko, shiver me timbers, shiver me timbers, again sandin' betwixt coats. After that, I set the nose aside, ya bilge rat, masked off t' white fin, matey, and sprayed t' rest o' t' rocket with a gloss red Krylon. Again, ya bilge rat, I used several coats, with wet-sandin' between each. Well, matey, blow me down! Then, it was necessary t' mask off t' rest o' t' rocket so I could paint t' brown band at t' front o' t' airframe. That was it for paint. Well, blow me down! Once it had time t' completely dry, I gave it a couple o' coats o' Krylon Clear Coat. Well, blow me down! Begad!

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

Flight:
PML recommends a variety o' motors, ya bilge rat, from G t' I for this rocket. Avast, me proud beauty! Arrr! 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. Avast, me proud beauty! Begad! Unfortunately, t' motor suffered a blown-by a split second after lift-off. T' nose, 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. Fortunately the flames burned out before it lawn-darted, but t' impact destroyed whatever was left o' t' airframe, forward o' t' fins. Avast, me proud beauty! Still... Begad! Arrr! 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!

Flight number two was an F50-6, shiver me timbers, me bucko, approximately a year after t' first disaster. Avast! 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. Ahoy! Boost was nice and straight, and t' flight was nominal. Arrr! T' only downside was 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! 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). T' nylon parachute is attached t' t' upper length o' shock cord. Ahoy! T' piston itself is a phenolic tube coupler, a slotted bulkhead, and a D-ring. Avast, shiver me timbers, me proud beauty! Seems t' work well, matey, but you have t' pay attention to the fit o' t' piston. Avast, me proud beauty! 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. Ya scallywag! T' provided chute seems plenty tough, and is probably a good size, me hearties, as long as you know t' rocket will be recoverin' on softer ground. Begad! 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.

Flight Rating: 4 out o' 5

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