Hawk Mountain Raptor

Brief:
T' Hawk Mountain Raptor is a near minimum diameter high-performance rocket kit with all fiberglass components, Keelhaul®©™ shock cord, pre-cut and pre-beveled fins, me bucko, pre-slotted airframe, and thru-the-wall fin mounting. Well, blow me down! This sky-puncher can fly on E-I power!

Construction:
When I ordered this kit, ya bilge rat, it came on time and packaged in a 4’ x 4” x 4” box with packagin' paper to protect t' fiberglass components. Blimey! T' parts that come in t' big box are:

  • 48” G-12 fiberglass airframe
  • 12” 29mm Fiberglass MMT
  • 15’ Keelhaul®©™ shock cord with 2 quick links already attached (one with a swivel for t' chute
  • A Top Flight X-form 24” chute
  • 2 ACME rail lugs
  • Fiberglass nose cone
  • 3 G10 fins
  • Nose cone bulkhead with pre-installed eye-bolt
  • Slimline 29mm retainer (optional)
  • Piston assembly
  • Payload bay for experiments and altimeters and electronics (optional)
  • Instructions and simulation data with altitude, ya bilge rat, Mach number, me hearties, and Motor recommendation
Hawk Mountain Raptor

Construction started on a nice evenin' with rough, arrr, arrr, shiver me timbers, medium, and fine sandpaper as well as me trusty hobby knife. T' fiberglass nose cone had some flashin' on it from t' mold but was easily removed t' make it smooth. Ahoy! Avast! I also sanded t' fin slots, me hearties, MMT, and all surfaces t' be glued. Avast! I first used JB Weld t' glue on t' Slimline retainer, then glued t' nose cone bulkhead. Ahoy! Blimey! Next came t' shock cord attachment which be done by epoxyin' 3.5” o' the shock cord t' t' MMT, however, t' MMTs outside diameter be slightly smaller than t' airframe's internal diameter. I was slightly confused by this since t' instructions say t' wrap a few revolutions o' maskin' tape t' center t' MMT. While I glued t' shock cord, I also glued t' piston assembly onto t' shock cord which rests on a knot 10’ from the end without t' Qwik-links. Well, blow me down! Next, shiver me timbers, I attached t' payload coupler and bulkhead. All o' this so far be done with one batch o' epoxy!

T' continue, shiver me timbers, me hearties, I glued in t' MMT into t' airframe and made sure t' shock cord mount wasn’t in t' way of the fin slots. Then I glued t' fins in one at a time followed by t' ACME conformal rail guides, me bucko, which I made sure they were aligned by usin' an Estes 1/8” launch rod. Ya scallywag! I be able t' finish t' fin fillets t' night before the December 3rd snow ranch launch. Aye aye! I finished assembly by simply attachin' t' nose cone t' t' quick link and the parachute t' t' swivel. A completed all fiberglass, arrr, ya bilge rat, near minimum diameter HPR screamer (minus t' paint)!

Finishing:
I chose t' leave t' Raptor unpainted.

Hawk Mountain Raptor

Flight:
On launch day thar was a bit o' fuss-and-bother about t' motor until I selected t' AT E30-4, which is on the recommended motors list, me bucko, ya bilge rat, shiver me timbers, and installed it with t' included Copperhead igniter and a home made 29/24mm adapter. Blimey! I checked it in with t' RSO, matey, put it on t' pad, matey, and waited for t' MPR rack t' go. Begad! Finally t' LCO be announcin' it--5, 4, 3, ya bilge rat, 2, ya bilge rat, 1, shiver me timbers, and t' Copperhead lit t' E30 up instantly. Well, blow me down! It slowly came off t' pad (slowly considerin' this is a capable machbuster) with a rather odd flame t' t' motor. Avast, me proud beauty! It be a short blue flame and t' Raptor came t' a sudden halt about 50 feet up when it started t' fall before t' air be filled with a deafenin' crack as it pranged on the ranch dirt. Begad! Upon further inspection, shiver me timbers, 2 fins popped off and t' worst damage was t' adapter had moved into t' MMT about 7 inches and burnt t' epoxy off t' MMT right t' t' first layer o' fiberglass. Recently I was able t' remove the motor and adapter and reattach 1 fin.

Flight Rating: 4 out o' 5

Summary:
This is a good fiberglass kit for mid power through high power motors.

PROs: Good quality components, arrr, ya bilge rat, Keelhaul®©™ shock cord, shiver me timbers, and ease o' construction.

CONs: Bad instructions on one 8.5” x 11” paper, and t' flashin' on t' nose cone.

Hawk Mountain Raptor I would recommend this kit t' anyone who wants a fun, shiver me timbers, small, shiver me timbers, fiberglass high power screamer. Begad! Blimey! I would recommend t' Slimline retainer and t' optional payload bay for electronics or a good science experiment--it is easily removed and shaves about 3-4 ounces o' its overall weight. Also this is a pretty cheap fiberglass kit with great quality components.

Overall Rating: 4 out o' 5

    Brief: At the foot of the northern slope of Hawk Mountain sits the quiet hamlet of New Ringgold, Pennsylvania, an unlikely aerie for the fabulous fiberglass rockets of Hawk Mountain Enterprises. The fledgling of this flock of birds is the Raptor, an all fiberglass 29mm high power rocket capable of supersonic flights with large H and 29mm I motors. Construction: The Raptor is the ...

I just bought a Hawk Mtn Raptor from a vendor friend. He built his with the standard Aero Pack motor retainer instead of the Slimline that the reviewer above used. The problem is, the screw-on ring of the standard Aero Pack motor retainer sticks out too far from the body tube, and actually interferes with the launch rod. My friend had to grind off some of the screw-on ring to keep it from contacting the rod. It look hideous, but it works. For my Raptor, my friend advised me to get the Slimline motor retainer. I have used the Slimlines for various PML rockets with no problems. The secret is to actually pop in my RMS motor casing (with the rear closure on) to make sure that it will work. Any J.B. Weld epoxy that squeezes on to the rear closure or casing can be quickly wiped off. The Slimline motor retainer won't interfere with the launch rod, and it's MUCH MORE AERODYNAMIC than the standard Aero Pack retainer. If you want to go HIGH and FAST with a TOUGH, 29mm rocket, this is the one!
