Brief:
This is a semi-scale model o' t' Canadian soundin' rocket, arrr, me hearties, manufactured by Bristol Aerospace. Blimey! Accordin' t' PML, me bucko, 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), a 4:1 ogive plastic nose cone, me bucko, plywood centerin' rings, a 30 inch nylon parachute, me hearties, 38mm phenolic motor mount tube, shiver me timbers, 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. Begad! 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, and use bigger motors. Aye aye! Ya scallywag! However, me hearties, if you intend t' stick t' mid-power motors, shiver me timbers, and H or light I motors, me bucko, then QT is by far t' way t' go. Ya scallywag! I really likely nay havin' t' fill in that spiral, shiver me timbers, which I've found can be a pretty serious job on phenolic tubes. Avast, me proud beauty! 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! There's not a lot you can write up, me bucko, for a basic 3FNC rocket anyway. Arrr! Construction steps are logical, and any "gotcha's" are pointed out... 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, shiver me timbers, ya bilge rat, I build the kit stock, except for t' home-made motor retention, ya bilge rat, arrr, and t' addition o' a vent-hole in me second one (the QT version). Ahoy!

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

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, me hearties, 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, matey, even with t' 29mm adapter in place. Ahoy! Overall, 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. 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. Well, blow me down! With t' QT, arrr, all I have t' do be rough it up a bit t' help t' primer adhere! Paintin' was pretty simple. Ahoy! 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, again sandin' betwixt coats. Ahoy! After that, I set the nose aside, masked off t' white fin, ya bilge rat, arrr, me bucko, and sprayed t' rest o' t' rocket with a gloss red Krylon. Arrr! Again, shiver me timbers, I used several coats, with wet-sandin' between each. Then, arrr, it was 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. Blimey! Once it had time t' completely dry, me bucko, I gave it a couple o' coats o' Krylon Clear Coat. Well, blow me down! Avast, shiver me timbers, me proud beauty!

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

Flight:
PML recommends a variety o' motors, me hearties, from G t' I for this rocket. 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. Begad! T' nose, arrr, piston and parachute were blown free (the nylon strap be burned through), arrr, 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, matey, forward o' t' fins. Still... 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.

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. Boost was nice and straight, matey, shiver me timbers, and t' flight was nominal. T' only downside be t' rocket landin' on a runway, which scarred it a bit, ya bilge rat, arrr, 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, is connected to the nose cone by a length o' woven elastic (I understand this has recently been replaced with tubular nylon). Well, blow me down! Blimey! T' nylon parachute is attached t' t' upper length o' shock cord. T' piston itself is a phenolic tube coupler, arrr, a slotted bulkhead, me bucko, and a D-ring. Begad! Ahoy! Seems t' work well, but you have t' pay attention to the fit o' t' piston. Ahoy! 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! Begad! T' provided chute seems plenty tough, and is probably a good size, matey, me hearties, 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. Begad!

Flight Rating: 4 out o' 5

Summary:
Overall, I'm very happy with me Black Brant Vb. Avast, me proud beauty! Ahoy! 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. Ya scallywag! Avast! As for pros and cons... well, 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. In fact, it's simplicity is probably its biggest pro, making it a good startin' point in HPR.
