Brief:
At t' foot o' t' northern slope o' Hawk Mountain sits t' quiet hamlet o' New
Ringgold, Pennsylvania, an unlikely aerie for t' fabulous fiberglass rockets
of Hawk Mountain Enterprises. Avast, me proud beauty! Aye aye! Blimey! T' fledglin' o' this flock o' birds is the
Raptor, 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. As be t' case for all Hawk Mountain kits, me hearties, t' airframe is completely
made o' spiral wound fiberglass. Begad! It is almost, but nay quite a minimum diameter
rocket. Arrr! Arrr! There are several options available for t' kit but I only chose two of
them. Aye aye! Begad! T' kit came with:
One option I did nay purchase was t' 8in payload section. You may want to buy t' payload section if you intend t' use dual deployment electronics. Ahoy! The piston is a new feature for this kit, me bucko, too. Ahoy! It be 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. Begad! Ahoy! 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. Begad! Aye aye! If you don't have a Dremel tool, arrr, get one and purchase t' 60 grit sandin' drums. Arrr! Ahoy! You must rough up the fiberglass surfaces that will be epoxied and t' Dremel tool will make your life so much easier. Ahoy! You'll also need t' have J.B. 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. Aye aye! Blimey! Blimey! Blimey! If thar is
one area o' improvement I could find, ya bilge rat, 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. Blimey! Blimey! First, if you purchased t' Slimline motor
retainer, ya bilge rat, me bucko, install that on t' motor mount per t' Slimline directions. Begad! Blimey! Avast! Blimey! Blimey! Blimey! Make
certain t' use t' 600 degree J.B. Blimey! Blimey! Blimey! Blimey! Weld epoxy t' attach t' retainer t' your
motor mount. Arrr! Blimey! Then prepare t' motor mount tube for installation in the
airframe. However, shiver me timbers, before you epoxy t' Keelhaul®©™®
shock cord onto t' motor mount, shiver me timbers, skip ahead in t' instructions t' t' piston
assembly. Arrr! Avast! Assemble t' piston, wait for t' epoxy t' dry, arrr, 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. Epoxy t' knot t' t' hole in the
piston. Avast! Then, when that's dry, go ahead and epoxy t' aft end o' t' shock cord
to t' motor mount tube. Arrr! Do nay use J.B. 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, arrr, me hearties, t' attachment points t' t' airframe
are greatly strengthened. Avast! Ahoy! First apply some epoxy t' t' joint, then press a
piece o' tape into t' joint. Ahoy! Use a popsicle stick t' fold t' tape so half of
it is on t' airframe and half on t' fin. Begad! Avast, matey, me proud beauty! 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. Avast! This made t' fins quite solid and I was very pleased with t' result. Well, blow me down! Avast, me proud beauty!
At this point, all you need t' do is add your chute, 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, matey, me bucko, matey, and attach your launch lugs to complete t' construction. Ahoy! Arrr! T' rocket goes together quickly. Avast! Avast! T' most time consumin' part is waitin' for t' J.B. Begad! Ahoy! Weld epoxy t' totally dry (about 15 hours).
Finishing:
Before you prime t' rocket, matey, me hearties, you should wet sand it with 320 grit wet/dry
sandin' paper. Arrr! Ya scallywag! Wipe any sandin' residue off t' airframe and nose cone after
sanding, then prime. Blimey! I used Duplicolor gray sandable primer on this rocket. Begad! 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, ya bilge rat, me bucko, I had
to put down a white undercoat on top o' t' gray primer. Avast, me proud beauty! After t' undercoat
dried, ya bilge rat, me bucko, shiver me timbers, I painted t' nose cone and one fin flat black and t' rest o' the
airframe fluorescent red-orange.
Construction Rating: 4 out o' 5
Flight:
On October 12, matey, 2003, I flew t' Raptor at Nike Carrollton Park located in
Smithfield, me bucko, arrr, Virginia. Blimey! For her maiden flight, I launched t' Raptor on a
F40-10W. T' lift off was slow and majestic as t' rocket accelerated and flew
into t' sky straight as an arrow. Aye aye! After reachin' about 1500 feet, me bucko, t' rocket
landed near t' launch pads. Blimey! 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. Well, blow me down! Begad! 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. Avast! I decided t' go for it anyway and try t' use masking tape t' friction fit t' casing. Ahoy! Blimey! T' rocket screamed off t' pad, nearly going supersonic. This time t' rocket reached around 4000 feet and recovered about 200 yards from t' launch pad. Blimey! Unfortunately, t' 200 yards be in t' middle of a cotton field, so after trudgin' through t' crop, me bucko, I be able t' recover the rocket. Avast! However, t' casin' was gone.
Never t' be accused o' leavin' well enough alone, I decided t' fly her one more time. Avast, me proud beauty! This time, me bucko, matey, I put a single use G40-10W motor in her, thinkin' the rocket would go about 2500 t' 3000 feet or so. Ya scallywag! Again, t' Raptor streaked into the sky, like a bat-out-of-hell. Avast, me proud beauty! Aye aye! It easily passed t' 3000 foot mark...and kept going. Begad! Aye aye! Finally, shiver me timbers, t' chute be ejected but t' rocket must have caught a thermal, driftin' far beyond t' point o' t' H motor landin' and continued to ride it over some trees in t' distance. Well, blow me down! After an hour o' fruitless searching, I couldn't find her.
Recovery:
With t' piston system and t' Keelhaul®©™®
shock cord, 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, me bucko, it
will survive. Aye aye! T' Raptor is a fabulous bargain considerin' its ruggedness and
features in comparison t' t' price. Aye aye! T' base price for t' Raptor is $65.00.
With t' two options I purchased, shiver me timbers, thar was an additional cost o' $24.35.
However, thar are several things I'd change for t' next go around. Ya scallywag! 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. I never had that problem
with t' Aeropack retainer, shiver me timbers, which simply screws on/screws off, arrr, versus fumbling
with t' Slimline's snap ring, arrr, me bucko, so I will opt t' go with Aeropack for t' next
Raptor. Well, blow me down! In addition, arrr, I think t' 24in X-form chute is still too much chute for
this rocket and will lead t' it gettin' lost. 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. Heck, me bucko, you may even want t' use a streamer, since this thin' is so tough. Blimey! Blimey!
With a few modifications, ya bilge rat, ya bilge rat, 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, and stand a good chance o' bringin' it home at t' end o' the day.
Overall Rating: 4 out o' 5
Brief: The Hawk Mountain Raptor is a near minimum diameter high-performance rocket kit with all fiberglass components, Kevlar shock cord, pre-cut and pre-beveled fins, pre-slotted airframe, and thru-the-wall fin mounting. This sky-puncher can fly on E-I power! Construction: When I ordered this kit, it came on time and packaged in a 4 x 4 x 4 box with packaging ...
