Brief:
This is a semi-scale model o' t' Canadian soundin' rocket, arrr, arrr, manufactured by Bristol Aerospace. Ya scallywag! 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 hearties, a 4:1 ogive plastic nose cone, me bucko, plywood centerin' rings, a 30 inch nylon parachute, 38mm phenolic motor mount tube, arrr, a 1/4 inch brass launch lug, a heavy-duty nylon strap, arrr, a length o' woven elastic, ya bilge rat, and some "peel 'n stick"-type decals.

I've had t' opportunity t' build both t' QT and phenolic version o' this kit. Arrr! Avast! Frankly, ya bilge rat, I don't really have a preference in which material I used, shiver me timbers, now that I've tried both. Ahoy! 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, and H or light I motors, matey, then QT is by far t' way t' go. I really likely nay havin' t' fill in that spiral, me bucko, ya bilge rat, which I've found can be a pretty serious job on phenolic tubes. Avast! Well, me bucko, blow me down! 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. Begad! Well, blow me down! There's not a lot you can write up, for a basic 3FNC rocket anyway. Begad! Construction steps are logical, matey, and any "gotcha's" are pointed out... Begad! 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, arrr, 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). Arrr!

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

No motor retention is provided, so I installed me own version of "Kaplow Klips", me bucko, a pair o' blind nuts in t' aft centerin' ring, 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, even with t' 29mm adapter in place. Well, ya bilge rat, blow me down! Overall, matey, 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, 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! Blimey! Paintin' was pretty simple. Avast! Blimey! I gave the ship a couple o' coats o' Krylon white primer, sandin' betwixt each coat. Ahoy! Avast! 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. Well, blow me down! Blimey! After that, matey, I set the nose aside, ya bilge rat, masked off t' white fin, shiver me timbers, and sprayed t' rest o' t' rocket with a gloss red Krylon. Again, I used several coats, shiver me timbers, ya bilge rat, with wet-sandin' between each. Begad! 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! That be it for paint. Once it had time t' completely dry, me bucko, matey, I gave it a couple o' coats o' Krylon Clear Coat. Avast! Blimey!

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

Flight:
PML recommends a variety o' motors, shiver me timbers, from G t' I for this rocket. Avast! 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. Blimey! Blimey! Unfortunately, matey, t' motor suffered a blown-by a split second after lift-off. Arrr! Blimey! T' nose, me hearties, 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. Well, blow me down! Blimey! Blimey! Blimey! Fortunately the flames burned out before it lawn-darted, matey, but t' impact destroyed whatever was left o' t' airframe, me hearties, forward o' t' fins. Avast! Blimey! Ya scallywag! Blimey! Still... Arrr! Blimey! despite t' sudden, low-speed deployment o' t' nose and chute (the rocket had just cleared the rod), me hearties, arrr, it had managed t' continue on a stable flight-path. Begad! Blimey!

Flight number two be an F50-6, matey, arrr, ya bilge rat, approximately a year after t' first disaster. Ya scallywag! PML does nay recommend anythin' smaller than a G for this rocket, me hearties, but Rocksim shows a predicted altitude o' about 700 feet on this motor. Aye aye! Blimey! Boost was nice and straight, arrr, matey, and t' flight be nominal. Begad! Blimey! T' only downside was t' rocket landin' on a runway, which scarred it a bit, matey, ya bilge rat, 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. Begad! T' piston, arrr, in turn, me bucko, is connected to the nose cone by a length o' woven elastic (I understand this has recently been replaced with tubular nylon). Begad! Arrr! T' nylon parachute is attached t' t' upper length o' shock cord. Begad! Avast, me proud beauty! T' piston itself is a phenolic tube coupler, a slotted bulkhead, and a D-ring. Seems t' work well, me bucko, but you have t' pay attention to the fit o' t' piston. 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. Begad! T' provided chute seems plenty tough, me hearties, and is probably a good size, me hearties, 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. Begad!

Flight Rating: 4 out o' 5

Summary:
Overall, matey, shiver me timbers, I'm very happy with me Black Brant Vb. Avast! It's a slick-lookin' rocket, and flies on a nice variety o' motors. 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. As for pros and cons... Avast, me proud beauty! Aye aye! well, arrr, me bucko, arrr, 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! In fact, shiver me timbers, it's simplicity is probably its biggest pro, making it a good startin' point in HPR.
