Manufacturer: THOY
Style: Sport

Brief:

With my Night HawkT' Night Hawk is an awesome (yet simple) 7x29mm cluster rocket made by THOY. Aye aye! I received this rocket as a Christmas present a few years back. It has very easy construction, and can fly on about any combination o' 1, 2, matey, ya bilge rat, arrr, 3, me hearties, 4, shiver me timbers, 5, 6, matey, 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, me hearties, (2) centerin' rings, shiver me timbers, (7) 29mm motor tubes (3 long, me bucko, 4 short), (3) plywood fins, a steel cable shock cord mount, a 36" fluorescent orange 'chute, ya bilge rat, arrr, a 1" wide black elastic shock cord, ya bilge rat, an ACE 3.9" nose cone, a 3.9" booster/payload coupler, a 1/2" launch lug, and a plywood bulkhead with an eye hook for shock cord attachment. Blimey! T' airframe tubin' was thick paper (like LOC tubing), ya bilge rat, and all o' t' parts were undamaged, and o' good quality.

T' kit had standard construction, and went together smoothly. T' only problem I had in construction be installin' t' fins. Ya scallywag! Avast! T' rocket has through-the-wall fin mounting, arrr, and each fin tab is intended t' slip through t' slot in t' body tube, ya bilge rat, and fit betwixt two o' t' seven motor tubes. Ya scallywag! When I did this, ya bilge rat, t' fins did nay go in all o' t' way, and therefore left a nasty gap along t' fin root. Arrr! Avast, me proud beauty! I solved t' problem by fillin' t' gap with putty, me hearties, but I do nay know if I aligned t' tubes incorrectly, or if t' tabs were cut too long. Avast, me proud beauty! Either way, arrr, t' rocket still went together very well, and looked very nice. Begad! It is quite large, me hearties, too, matey, (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. I finally ended up with an all black body, me bucko, me hearties, with U.S. Blimey! Air Force decals on it. Blimey! Avast, me proud beauty! I painted it with sanded grey primer, and Krylon spray paint. Begad! Avast! I also made 1 other change on t' rocket. Well, blow me down! I replaced t' 1/2" launch lug with 2 1/4" launch lugs, and covered up t' nasty, hard t' sand putty on t' fin roots with epoxied on strips o' construction paper. Hey... I know it sounds cheap, arrr, 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, matey, shiver me timbers, 2000 launch. Avast, me proud beauty! Well, matey, blow me down! I chose t' fly it on a three-in-line cluster o' (1) G38-4FJ, and (2) F23-4FJs (a 206NS H94-4FJ equivalent). Avast! T' motors were friction fitted into place, me bucko, arrr, and I then ran into t' problem o' nay havin' good low current igniters. Ahoy! So... Avast, me proud beauty! Aye aye! I consulted some people, and I ended up with some igniters called "Firestarter" (not Firestar) igniters. T' man that donated them said they were pretty good- especially when he first used them. Arrr! He said he had had some misfires lately with them. Avast, me proud beauty! Despite this, I took them, arrr, arrr, and loaded them into t' rocket, and wired them in parallel. Then, 5...4...3...2...1... Avast! 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 was a bit too small, and it descended a little too fast for me liking. Aye aye! Blimey! It cracked one o' t' fin roots on landing. So... Begad! I then took on t' adventure o' glassin' t' booster (main) section o' t' rocket, t' fins, and t' fin roots. T' process was messy, matey, but it came out all right for me first try at it. Ahoy! I then had t' refinish t' rocket. Ahoy! Well, ya bilge rat, blow me down! So, matey, I filled t' glass with vinyl spackling, arrr, matey, and put a wrap o' clear lamination sticker on t' payload t' make it all smooth and pretty. Then, me hearties, t' rocket was once again primed, sanded, and painted. Avast! Well, me bucko, blow me down! I painted it just gloss black this time, shiver me timbers, and put no decals on it (but I will someday soon :-) Lastly, me bucko, arrr, t' slow down recovery speed, I left t' 36" 'chute on t' main body, but attached two smaller chutes t' t' payload, matey, so that each section could descend slowly, matey, arrr, and separately. Ahoy! I also attached rail guides, and threw out t' old 1/4" lugs. Begad! Now it was time for flight two. Arrr! T' motors o' choice here were (2) F50-4Ts, me bucko, and (1) RMS F52-5T reload (a 240NS H146T). This time around, me hearties, I made sure I got good igniters, shiver me timbers, so I ordered some Trailin' Edge Technologies Fire-in-the-Hole low current tungsten igniters. Aye aye! T' second flight was at t' ROCC April 2001 launch. T' new igniters worked t' perfection, me bucko, 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). Begad! T' separate recovery worked perfectly here, and t' rocket only suffered some paint chipping. Aye aye! Well, blow me down! T' flight was great.

Flight Rating: 3 out o' 5

Summary:

PROS: T' Night Hawk looks sharp, matey, ya bilge rat, is easy t' build, and flies great on about any motor combination you can think of... Aye aye! but make sure you build it strongly! CONS: T' chute is a bit too small, matey, you must make sure you line t' motor tube gaps with t' fin slots, arrr, 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.
