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

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

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

T' rings fit a bit loosely, me bucko, matey, 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. Begad! Blimey! Blimey! Blimey! I put a 1/4" slot in a piece o' masonite with a 4" diameter arc at one end t' align t' main fins. Well, blow me down! Blimey! T' secondary fins were added later, and aligned by clampin' wooden stakes betwixt t' main and secondary fins. T' fin tabs were 1/16 t' 3/32" too long, arrr, and so t' fin roots were "elevated" off t' body tube, requirin' a fillet under them.

I added a PML modular baffle at t' top o' t' motor mount, matey, shiver me timbers, and T-nuts for motor retention at t' aft centerin' ring. Ya scallywag! Aye aye! I also added T-nuts t' retain rail buttons. Avast! I did this by nay securin' t' aft centerin' rin' until after the motor tube was glued in. Begad! This allowed me t' get into t' area betwixt the middle and aft rin' and glue (with thickened epoxy) t' T-nuts. Begad! Begad!

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. Ya scallywag! Blimey!

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

Finishing:
I didn't finish it. Begad! 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, ya bilge rat, me bucko, I2110-10, I357-6, I161-6, I156-6. Blimey! 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. Ya scallywag! You need to pack it carefully t' fit. Avast, me proud beauty! Well, blow me down!

There be a light wind.

Immediately after leavin' t' rail, arrr, t' rocket went into skywriter mode, did about 4 full loops, and landsharked under full power. Ejection occurred after t' landshark.

Recovery:
On impact, shiver me timbers, arrr, one fin ripped off. Aye aye! T' payload bay had a slight crinkle. Avast, me proud beauty! T' damage should be easily repairable, ya bilge rat, arrr, 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. Ya scallywag! I'll also be able t' get more room for t' chute by shortenin' t' coupler.

DEFINITELY ADD NOSE WEIGHT. Aye aye! Ahoy! This rocket is unstable if built accordin' to the manufacturer's instructions. Avast! If anything, shiver me timbers, me CG was forward o' standard, 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' loot. Blimey! Blimey! Pretty rocket. Avast! Blimey! Avast, me proud beauty! Blimey! Lots o' people were wondering where I got it. Avast, me proud beauty! Blimey! If only t' vendor would talk about nose weight in the instructions, t' flight ratin' would have been higher (e.g., ya bilge rat, about a 4, I bet).

Overall Rating: 3 out o' 5
