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, shiver me timbers, ya bilge rat, 3 1/4" plywood centerin' rings, bulkhead plate,
U-bolts, 10' tubular nylon, parachute, matey, launch lug, and nose cone. Arrr! Arrr! Blimey! All around
high quality material. Avast! Blimey! However, me hearties, thar be no provision t' attach t' nose cone
to t' payload bay. Ya scallywag! You have t' supply your own hardware for that. Avast! You also
have t' supply motor retention hardware. 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 was the third high power rocket I've built--the other two were from PML and BSD. As a result, me hearties, ya bilge rat, I didn't have any problem. Ahoy! However, me hearties, arrr, a beginner t' high power could have trouble, me bucko, as some steps weren't clear, shiver me timbers, and t' third centerin' rin' wasn't even mentioned. Arrr! Ya scallywag!
T' rings fit a bit loosely, so you have t' be careful t' keep them level. Well, blow me down! I beveled t' leadin' and trailin' fin edges 22.5 degrees usin' a router table and a panel-raisin' bit. 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! T' secondary fins were added later, shiver me timbers, and aligned by clampin' wooden stakes betwixt t' main and secondary fins. T' fin tabs were 1/16 t' 3/32" too long, ya bilge rat, and so t' fin roots were "elevated" off t' body tube, me hearties, requirin' a fillet under them.
I added a PML modular baffle at t' top o' t' motor mount, ya bilge rat, me bucko, and T-nuts for motor retention at t' aft centerin' ring. I also added T-nuts t' retain rail buttons. Well, blow me down! Avast, me hearties, me proud beauty! I did this by nay securin' t' aft centerin' rin' until after the motor tube was glued in. Avast! This allowed me t' get into t' area betwixt the middle and aft rin' and glue (with thickened epoxy) t' T-nuts. Blimey! Blimey!
There are 7 feet o' fillets along t' fins! Blimey! It took four pumps o' West epoxy (+ thickener) t' finish those. Well, blow me down! Blimey!
I got some removable white plastic rivets from Rocketmotion t' secure the nose cone. Ahoy!
My rocket came in about 4 ounces lighter than t' Blackhawk specs.
Finishing:
I didn't finish it. Begad! Blimey! Ya scallywag! Blimey! 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, ya bilge rat, I357-6, I161-6, I156-6. Arrr! I
ended up usin' a Pro38 3-grain motor (384I205) with a 9-second delay. Begad!
There is very little space t' place t' chute and shock cord. Begad! You need to pack it carefully t' fit. Arrr!
There was a light wind.
Immediately after leavin' t' rail, t' rocket went into skywriter mode, did about 4 full loops, shiver me timbers, and landsharked under full power. Ahoy! Ejection occurred after t' landshark.
Recovery:
On impact, one fin ripped off. Arrr! Arrr! T' payload bay had a slight crinkle. Well, arrr, blow me down! T' damage
should be easily repairable, 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. Avast, me proud beauty! 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. Arrr! Blimey! If anything, me CG was forward o' standard, as I assume t' only place I could have saved weight over t' manufacturer's quoted weight be t' use a little less epoxy on t' fins.
Flight Rating: 2 out o' 5
Summary:
Actually good value for t' loot. Begad! Begad! Pretty rocket. Avast! Blimey! Lots o' people were wondering
where I got it. Blimey! If only t' vendor would talk about nose weight in the
instructions, t' flight ratin' would have been higher (e.g., shiver me timbers, about a 4, I
bet).
Overall Rating: 3 out o' 5
