Manufacturer: THOY
Style: Sport

Brief:

With my Night HawkT' Night Hawk is an awesome (yet simple) 7x29mm cluster rocket made by THOY. Avast! Blimey! I received this rocket as a Christmas present a few years back. Begad! Blimey! It has very easy construction, arrr, ya bilge rat, and can fly on about any combination o' 1, ya bilge rat, 2, 3, 4, matey, ya bilge rat, 5, 6, or 7 29mm motors.

Construction:

T' rocket came in a plastic bag with (1) long 3.9" airframe tube, (1) short 3.9" payload tube, (2) centerin' rings, (7) 29mm motor tubes (3 long, me hearties, matey, 4 short), ya bilge rat, (3) plywood fins, ya bilge rat, ya bilge rat, a steel cable shock cord mount, arrr, matey, a 36" fluorescent orange 'chute, matey, a 1" wide black elastic shock cord, ya bilge rat, an ACE 3.9" nose cone, shiver me timbers, a 3.9" booster/payload coupler, me hearties, a 1/2" launch lug, ya bilge rat, ya bilge rat, and a plywood bulkhead with an eye hook for shock cord attachment. Avast! Blimey! T' airframe tubin' was thick paper (like LOC tubing), and all o' t' parts were undamaged, matey, and o' good quality.

T' kit had standard construction, and went together smoothly. Ya scallywag! Blimey! Well, blow me down! Blimey! T' only problem I had in construction was installin' t' fins. Well, blow me down! Blimey! Ahoy! Blimey! T' rocket has through-the-wall fin mounting, arrr, and each fin tab is intended t' slip through t' slot in t' body tube, and fit betwixt two o' t' seven motor tubes. Avast, me proud beauty! Blimey! Arrr! Blimey! When I did this, t' fins did nay go in all o' t' way, and therefore left a nasty gap along t' fin root. Avast! Blimey! I solved t' problem by fillin' t' gap with putty, ya bilge rat, but I do nay know if I aligned t' tubes incorrectly, or if t' tabs were cut too long. Blimey! Blimey! Either way, me bucko, t' rocket still went together very well, and looked very nice. Begad! Blimey! Avast! Blimey! It is quite large, matey, too, me hearties, (about 5 feet tall) so it stands out.

Finishing:
In t' year betwixt construction and t' first flight o' this rocket, it went through three different paint schemes. Aye aye! Begad! Blimey! I finally ended up with an all black body, with U.S. Blimey! Air Force decals on it. I painted it with sanded grey primer, me bucko, matey, and Krylon spray paint. Avast, me proud beauty! I also made 1 other change on t' rocket. Begad! I replaced t' 1/2" launch lug with 2 1/4" launch lugs, arrr, and covered up t' nasty, me bucko, hard t' sand putty on t' fin roots with epoxied on strips o' construction paper. Avast! Ahoy! Blimey! Hey... Begad! I know it sounds cheap, me hearties, but it worked!

Construction Rating: 4 out o' 5

Getting ReadyFlight:

T' first flight o' t' Night Hawk was at t' ROCC (Rocketry O' Central Carolina) November, ya bilge rat, 2000 launch. Avast! Well, blow me down! I chose t' fly it on a three-in-line cluster o' (1) G38-4FJ, arrr, and (2) F23-4FJs (a 206NS H94-4FJ equivalent). Blimey! T' motors were friction fitted into place, shiver me timbers, and I then ran into t' problem o' nay havin' good low current igniters. So... Ya scallywag! I consulted some people, shiver me timbers, me bucko, and I ended up with some igniters called "Firestarter" (not Firestar) igniters. Arrr! T' man that donated them said they were pretty good- especially when he first used them. He said he had had some misfires lately with them. Ahoy! Despite this, I took them, and loaded them into t' rocket, me bucko, and wired them in parallel. Arrr! Then, 5...4...3...2...1... Arrr! Begad! LIFTOFF! All three motors lit, and t' rocket ROARED off o' t' t' pad on an awesome column o' black smoke.

LaunchingRecovery:

T' rocket ejected at apogee, ya bilge rat, but t' 'chute be a bit too small, and it descended a little too fast for me liking. Aye aye! It cracked one o' t' fin roots on landing. Well, blow me down! So... Avast! Ya scallywag! I then took on t' adventure o' glassin' t' booster (main) section o' t' rocket, t' fins, ya bilge rat, and t' fin roots. Begad! T' process was messy, arrr, but it came out all right for me first try at it. Aye aye! Avast, ya bilge rat, me proud beauty! I then had t' refinish t' rocket. Begad! So, I filled t' glass with vinyl spackling, me bucko, and put a wrap o' clear lamination sticker on t' payload t' make it all smooth and pretty. Avast! Then, t' rocket was once again primed, matey, ya bilge rat, sanded, and painted. Begad! I painted it just gloss black this time, shiver me timbers, and put no decals on it (but I will someday soon :-) Lastly, t' slow down recovery speed, shiver me timbers, me bucko, I left t' 36" 'chute on t' main body, arrr, but attached two smaller chutes t' t' payload, shiver me timbers, so that each section could descend slowly, and separately. Well, blow me down! I also attached rail guides, and threw out t' old 1/4" lugs. Now it was time for flight two. T' motors o' choice here were (2) F50-4Ts, and (1) RMS F52-5T reload (a 240NS H146T). Blimey! This time around, shiver me timbers, I made sure I got good igniters, so I ordered some Trailin' Edge Technologies Fire-in-the-Hole low current tungsten igniters. T' second flight was at t' ROCC April 2001 launch. T' new igniters worked t' perfection, and t' Night Hawk roared off o' t' rail into t' sky on a light trail o' Blue Thunder smoke with a little blue flame at ignition (I had t' look hard, though). Aye aye! T' separate recovery worked perfectly here, me hearties, shiver me timbers, ya bilge rat, and t' rocket only suffered some paint chipping. T' flight was great.

Flight Rating: 3 out o' 5

Summary:

PROS: T' Night Hawk looks sharp, is easy t' build, and flies great on about any motor combination you can think of... but make sure you build it strongly! CONS: T' chute is a bit too small, you must make sure you line t' motor tube gaps with t' fin slots, me bucko, and t' flight cost is goin' t' be more than single motor flights.

Overall Rating: 4 out o' 5

i know this is rather older review, but wanted to comment. i had a nighthawk and it was my favorite of my fleet. i sold it, and a lot of my fleet and supplies about 2 years ago, but am a BAR!!! currently working on  scratch building a nighthawk. it was an awesome rocket with many awesome flights.
