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

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

All t' parts fit well, 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, and a pair o' mirror mountin' brackets I picked up at t' hardware store. Ya scallywag! these things turned out t' be a perfect fit when usin' SU motors, even with t' 29mm adapter in place. Avast! Avast, matey, me proud beauty! 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. Ya scallywag! When I built the phenolic version o' this kit, matey, shiver me timbers, I spent a lot o' time fillin' and sandin' those darned spiral grooves in t' airframe. With t' QT, all I have t' do be rough it up a bit t' help t' primer adhere! Paintin' was pretty simple. Begad! 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, ya bilge rat, again sandin' betwixt coats. Ahoy! Aye aye! After that, I set the nose aside, masked off t' white fin, and sprayed t' rest o' t' rocket with a gloss red Krylon. Aye aye! Again, I used several coats, matey, with wet-sandin' between each. Aye aye! Then, matey, 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. Avast! Once it had time t' completely dry, me bucko, ya bilge rat, I gave it a couple o' coats o' Krylon Clear Coat. Begad!

Now, on t' real rocket, matey, thar be a narrow metal band at t' very top o' the airframe. Avast! Begad! T' replicate this, I used a strip o' silver decal from an auto detailin' kit. Avast! Arrr! It adheres well, and looks about right. Ya scallywag! Arrr! Also, matey, t' real rocket has a pair o' white stripes runnin' down t' side o' t' rocket. I chose t' not paint these, me bucko, since maskin' materials and I don't get along real well. Arrr! So, matey, arrr, I got a length o' white vinyl decal material from a local art supply shop. Aye aye! I made measurements from Peter Alway's Rockets o' t' World, ya bilge rat, matey, and cut out t' strips I needed. Ya scallywag! Ya scallywag! I was worried about how well this stuff would adhere, me bucko, but it's doing fine so far. Aye aye! After that, I applied t' decals, shiver me timbers, referencin' both t' kit instructions, arrr, ya bilge rat, and Rockets o' t' World. Well, blow me down! These went on with a minimum o' fuss (for peel 'n stick, anyway). Arrr! Finally, I applied a final coat o' clear t' seal everything. Avast! Avast, shiver me timbers, 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. My first flight (and only, for t' phenolic one) be t' be me CAR level 1 cert flight, usin' an H123 with a 10 second delay. Arrr! Unfortunately, me bucko, t' motor suffered a blown-by a split second after lift-off. Avast! Well, blow me down! T' nose, arrr, 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. Fortunately the flames burned out before it lawn-darted, arrr, but t' impact destroyed whatever was left o' t' airframe, matey, me bucko, forward o' t' fins. Begad! Still... Blimey! despite t' sudden, low-speed deployment o' t' nose and chute (the rocket had just cleared the rod), me hearties, me hearties, it had managed t' continue on a stable flight-path. Ahoy! Aye aye!

Flight number two was an F50-6, approximately a year after t' first disaster. Blimey! PML does nay recommend anythin' smaller than a G for this rocket, shiver me timbers, but Rocksim shows a predicted altitude o' about 700 feet on this motor. Ya scallywag! Boost was nice and straight, ya bilge rat, and t' flight be nominal. Well, matey, blow me down! T' only downside be t' rocket landin' on a runway, me hearties, which scarred it a bit, shiver me timbers, ya bilge rat, 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. Ya scallywag! 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! T' nylon parachute is attached t' t' upper length o' shock cord. Begad! T' piston itself is a phenolic tube coupler, me hearties, matey, arrr, a slotted bulkhead, and a D-ring. Seems t' work well, me hearties, arrr, but you have t' pay attention to the fit o' t' piston. Begad! Begad! 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. Avast! T' provided chute seems plenty tough, me bucko, and is probably a good size, as long as you know t' rocket will be recoverin' on softer ground. Well, blow me down! Arrr! 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!

Flight Rating: 4 out o' 5

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