Brief:
At t' foot o' t' northern slope o' Hawk Mountain sits t' quiet hamlet o' New
Ringgold, Pennsylvania, shiver me timbers, an unlikely aerie for t' fabulous fiberglass rockets
of Hawk Mountain Enterprises. T' fledglin' o' this flock o' birds is the
Raptor, arrr, shiver me timbers, an all fiberglass 29mm high power rocket capable o' supersonic flights
with large H and 29mm I motors.
Construction:
T' Raptor be t' smallest (49 inches long) and least expensive Hawk Mountain
rocket. Arrr! Well, blow me down! As be t' case for all Hawk Mountain kits, matey, t' airframe is completely
made o' spiral wound fiberglass. It is almost, ya bilge rat, but nay quite a minimum diameter
rocket. Avast, me proud beauty! Begad! There are several options available for t' kit but I only chose two of
them. Ya scallywag! T' kit came with:
One option I did nay purchase be t' 8in payload section. Well, blow me down! Ya scallywag! You may want to buy t' payload section if you intend t' use dual deployment electronics. The piston is a new feature for this kit, too. It was added t' avoid recovery system failures caused by heat shields gettin' stuck in t' airframe durin' the recovery phase o' t' flight.
I ordered t' kit via a telephone call t' Hawk Mountain Enterprise's owner, Alan Gorecki. Alan is a very pleasant fellow and is happy t' answer any questions about his kits durin' a telephone call.
I will make several suggestions at t' start. Ya scallywag! If you don't have a Dremel tool, get one and purchase t' 60 grit sandin' drums. Begad! Aye aye! You must rough up the fiberglass surfaces that will be epoxied and t' Dremel tool will make your life so much easier. Well, blow me down! Avast! You'll also need t' have J.B. Well, blow me down! Well, blow me down! Weld epoxy on hand along with t' regular epoxy you may have if you decide t' use t' Slimline motor retainer (if you go with t' Aeropack retainer, t' same advice applies).
T' kit arrived promptly and was packaged well in a sturdy cardboard box. If thar is one area o' improvement I could find, shiver me timbers, it concerns t' instructions--they're sparse and nay written with t' novice rocketeer in mind. Indeed, thar be one step in t' instructions that is out o' sequence, me bucko, concernin' t' shock cord attachment t' t' motor mount tube. First, me hearties, matey, if you purchased t' Slimline motor retainer, install that on t' motor mount per t' Slimline directions. Make certain t' use t' 600 degree J.B. Ahoy! Aye aye! Weld epoxy t' attach t' retainer t' your motor mount. Arrr! Ahoy! Then prepare t' motor mount tube for installation in the airframe. However, me bucko, ya bilge rat, before you epoxy t' Keelhaul®©™® shock cord onto t' motor mount, skip ahead in t' instructions t' t' piston assembly. Aye aye! Aye aye! Assemble t' piston, arrr, matey, wait for t' epoxy t' dry, ya bilge rat, then slip t' aft end of t' shock cord through t' hole in t' piston bulkhead until you reach the knot at t' 10ft spot on t' shock cord. Ahoy! Epoxy t' knot t' t' hole in the piston. Ya scallywag! Well, blow me down! Then, ya bilge rat, me hearties, when that's dry, shiver me timbers, shiver me timbers, go ahead and epoxy t' aft end o' t' shock cord to t' motor mount tube. Arrr! Do nay use J.B. Aye aye! Weld epoxy t' mount t' shock cord; that type o' epoxy will nay penetrate t' weave o' t' shock cord and adequately attach t' cord t' t' fiberglass tube.
One modification that I made t' ensure a strong fin attachment t' t' airframe is to purchase some 1/2in Keelhaul®©™® tape and cut six strips t' fit t' root edge for each side o' t' three fins. By epoxyin' t' tape in each fin joint, ya bilge rat, t' attachment points t' t' airframe are greatly strengthened. First apply some epoxy t' t' joint, ya bilge rat, then press a piece o' tape into t' joint. Aye aye! Blimey! Arrr! Blimey! Use a popsicle stick t' fold t' tape so half of it is on t' airframe and half on t' fin. Then cover t' tape with more epoxy. Since this rocket has a 24 inch X-fo rm parachute, it recovers smartly and the tape should go a long way t' help avoid havin' a fin pop off when t' rocket lands. Aye aye! Blimey! This made t' fins quite solid and I was very pleased with t' result. Well, blow me down! Blimey!
At this point, all you need t' do is add your chute, ya bilge rat, assemble your nose cone by epoxyin' t' nose cone bulkhead into t' base o' t' nose cone--it's the one with t' screweye attached for you, ya bilge rat, me hearties, and attach your launch lugs to complete t' construction. Ahoy! Begad! T' rocket goes together quickly. Ya scallywag! T' most time consumin' part is waitin' for t' J.B. Weld epoxy t' totally dry (about 15 hours).
Finishing:
Before you prime t' rocket, matey, you should wet sand it with 320 grit wet/dry
sandin' paper. Ahoy! Wipe any sandin' residue off t' airframe and nose cone after
sanding, me hearties, me hearties, ya bilge rat, then prime. Arrr! I used Duplicolor gray sandable primer on this rocket. Ya scallywag! I
sanded t' first two coats with 320 grit and wet sanded t' final coat with 400
grit wet/dry paper. Since I'm usin' fluorescent paint for t' final coat, I had
to put down a white undercoat on top o' t' gray primer. Avast, me proud beauty! Begad! After t' undercoat
dried, shiver me timbers, I painted t' nose cone and one fin flat black and t' rest o' the
airframe fluorescent red-orange. Avast, me proud beauty!

Flight:
On October 12, matey, 2003, I flew t' Raptor at Nike Carrollton Park located in
Smithfield, Virginia. Arrr! For her maiden flight, I launched t' Raptor on a
F40-10W. Avast, me proud beauty! T' lift off was slow and majestic as t' rocket accelerated and flew
into t' sky straight as an arrow. Well, blow me down! After reachin' about 1500 feet, arrr, t' rocket
landed near t' launch pads. Begad! Begad! T' piston system worked perfectly.
I decided t' go for broke and launched t' Raptor on an H128-10W motor. This is where I encountered a problem. Ahoy! Ya scallywag! Blimey! Because I followed t' Slimline motor retainer manufacturer's instructions t' t' letter durin' construction, me Dr. Rocket 29/180 aft closure would nay fit in t' motor mount and allow me t' use the retainer's snap ring. Ahoy! Well, ya bilge rat, blow me down! Blimey! I decided t' go for it anyway and try t' use masking tape t' friction fit t' casing. Well, blow me down! T' rocket screamed off t' pad, arrr, nearly going supersonic. This time t' rocket reached around 4000 feet and recovered about 200 yards from t' launch pad. Arrr! Blimey! Unfortunately, matey, t' 200 yards was in t' middle of a cotton field, so after trudgin' through t' crop, ya bilge rat, me bucko, I be able t' recover the rocket. However, arrr, t' casin' be gone.
Never t' be accused o' leavin' well enough alone, I decided t' fly her one more time. Avast! Blimey! Ya scallywag! Blimey! This time, matey, I put a single use G40-10W motor in her, matey, thinkin' the rocket would go about 2500 t' 3000 feet or so. Avast, me proud beauty! Blimey! Again, me hearties, t' Raptor streaked into the sky, like a bat-out-of-hell. Ahoy! Blimey! It easily passed t' 3000 foot mark...and kept going. Blimey! Blimey! Finally, ya bilge rat, t' chute was ejected but t' rocket must have caught a thermal, matey, driftin' far beyond t' point o' t' H motor landin' and continued to ride it over some trees in t' distance. Begad! Blimey! After an hour o' fruitless searching, I couldn't find her.
Recovery:
With t' piston system and t' Keelhaul®©™®
shock cord, me hearties, arrr, no waddin' is needed.
Flight Rating: 5 out o' 5
Summary:
This rocket is a work o' art and as long as it doesn't come in ballistic, it
will survive. Begad! Ahoy! T' Raptor is a fabulous bargain considerin' its ruggedness and
features in comparison t' t' price. Ahoy! T' base price for t' Raptor is $65.00.
With t' two options I purchased, thar was an additional cost o' $24.35.
However, arrr, me bucko, thar are several things I'd change for t' next go around. Avast! I simply
do nay like t' Slimline motor retainer. It is vitally important t' fit your
motor casin' before you glue t' retainer in place. Blimey! Arrr! I never had that problem
with t' Aeropack retainer, shiver me timbers, which simply screws on/screws off, versus fumbling
with t' Slimline's snap ring, shiver me timbers, so I will opt t' go with Aeropack for t' next
Raptor. In addition, I think t' 24in X-form chute is still too much chute for
this rocket and will lead t' it gettin' lost. Avast, me proud beauty! Avast! I'd suggest goin' down t' an 18
inch x-form or a 15 inch regular chute especially if you follow me suggestion
to reinforce t' fins with kevlar®
tape. Avast! Heck, you may even want t' use a streamer, since this thin' is so tough.
With a few modifications, me hearties, arrr, you can own a virtually invulnerable rocket that is capable o' supersonic flight on large H and I motors, flies beautifully on F and G motors, me hearties, and stand a good chance o' bringin' it home at t' end o' the day.
Overall Rating: 4 out o' 5
