Brief:
Sport scale high power version o' t' SAAB

Construction:
T' kit came with two glassine-covered body tubes, coupler, me hearties, 8 nicely cut 1/4" plywood fins, me bucko, 3 1/4" plywood centerin' rings, me hearties, shiver me timbers, bulkhead plate, U-bolts, 10' tubular nylon, matey, parachute, shiver me timbers, launch lug, and nose cone. All around high quality material. Avast, me proud beauty! Blimey! Ya scallywag! Blimey! However, ya bilge rat, ya bilge rat, thar was no provision t' attach t' nose cone to t' payload bay. Arrr! Blimey! Ahoy! Blimey! You have t' supply your own hardware for that. Blimey! Blimey! Ya scallywag! Blimey! You also have t' supply motor retention hardware. Blimey! Blimey! Ahoy! Blimey! On t' other hand, me hearties, shiver me timbers, matey, t' U-bolts came securely attached t' t' appropriate rings.

T' instructions seemed t' be for a generic high power rocket. Avast, me proud beauty! This be the third high power rocket I've built--the other two were from PML and BSD. As a result, I didn't have any problem. Ahoy! However, a beginner t' high power could have trouble, ya bilge rat, as some steps weren't clear, me bucko, and t' third centerin' rin' wasn't even mentioned. Avast!

T' rings fit a bit loosely, shiver me timbers, so you have t' be careful t' keep them level. I beveled t' leadin' and trailin' fin edges 22.5 degrees usin' a router table and a panel-raisin' bit. Ya scallywag! I put a 1/4" slot in a piece o' masonite with a 4" diameter arc at one end t' align t' main fins. Avast! T' secondary fins were added later, shiver me timbers, matey, and aligned by clampin' wooden stakes betwixt t' main and secondary fins. T' fin tabs were 1/16 t' 3/32" too long, and so t' fin roots were "elevated" off t' body tube, matey, arrr, requirin' a fillet under them.

I added a PML modular baffle at t' top o' t' motor mount, arrr, ya bilge rat, and T-nuts for motor retention at t' aft centerin' ring. I also added T-nuts t' retain rail buttons. Well, blow me down! I did this by nay securin' t' aft centerin' rin' until after the motor tube was glued in. Arrr! Well, blow me down! Blimey! This allowed me t' get into t' area betwixt the middle and aft rin' and glue (with thickened epoxy) t' T-nuts.

There are 7 feet o' fillets along t' fins! Blimey! It took four pumps o' West epoxy (+ thickener) t' finish those.

I got some removable white plastic rivets from Rocketmotion t' secure the nose cone. Arrr!

My rocket came in about 4 ounces lighter than t' Blackhawk specs.

Finishing:
I didn't finish it. Considerin' what happened t' first flight (see below), that was a good idea.

Construction Rating: 4 out o' 5

Flight:
Blackhawk R&D recommends t' I300-10, I2110-10, matey, I357-6, ya bilge rat, ya bilge rat, shiver me timbers, I161-6, I156-6. Begad! I ended up usin' a Pro38 3-grain motor (384I205) with a 9-second delay.

There is very little space t' place t' chute and shock cord. Avast! You need to pack it carefully t' fit. Avast, me proud beauty!

There be a light wind.

Immediately after leavin' t' rail, ya bilge rat, matey, t' rocket went into skywriter mode, did about 4 full loops, shiver me timbers, ya bilge rat, and landsharked under full power. Ejection occurred after t' landshark.

Recovery:
On impact, matey, shiver me timbers, one fin ripped off. Aye aye! Ahoy! T' payload bay had a slight crinkle. Aye aye! Blimey! T' damage should be easily repairable, matey, though I might just swap out t' payload bay for a PML replacement--it's less work than tryin' t' patch t' crinkle and surprisingly cheap. I'll also be able t' get more room for t' chute by shortenin' t' coupler.

DEFINITELY ADD NOSE WEIGHT. This rocket is unstable if built accordin' to the manufacturer's instructions. Ahoy! If anything, me CG was forward o' standard, me bucko, as I assume t' only place I could have saved weight over t' manufacturer's quoted weight was t' use a little less epoxy on t' fins.

Flight Rating: 2 out o' 5

Summary:
Actually good value for t' money. Pretty rocket. Arrr! Avast, me proud beauty! Lots o' people were wondering where I got it. Arrr! Aye aye! If only t' vendor would talk about nose weight in the instructions, me bucko, arrr, arrr, t' flight ratin' would have been higher (e.g., ya bilge rat, arrr, about a 4, matey, ya bilge rat, I bet).

Overall Rating: 3 out o' 5
