Hawks Hobby Super Javelin

Brief:
I was provided with me Super Javelin for beta testing. Ahoy! This upscale is o' t' early Javelin model that came in an Estes combo kit and is designed for 24mm motors. Aye aye! A spacer is included with t' motor mount kit t' allow t' use of either Estes D or E motors. Ahoy! Begad! T' rocket recovers on a very nice 24 inch rip-stop nylon parachute. Aye aye! Ahoy! T' rocket is over 3 feet tall and weighs only 7 ounces. Aye aye! Begad! T' highly aerodynamic design produces some outstandin' flights.

Construction:
T' main body tube is 1.59 inches in diameter. Well, blow me down! T' three fins are laser cut basswood and surface mounted. Avast, me proud beauty! T' balsa nose cone is top quality and very smooth. A 5-inch long 24mm motor mount is installed with three light ply centering rings and includes a 3.75” engine hook for motor retention and a CR2050 kraft thrust ring. Ya scallywag! A Keelhaul®©™®/1/4” elastic shock cord combo is included along with two 3/16” launch lugs and a hefty eye screw. A two-color paint design and its name in a big black waterslide decal decorates t' rocket.

T' instructions are clear and include tons o' helpful illustrations. I modified t' construction o' t' motor mount t' allow installation o' t' engine hook usin' me standard method. Aye aye! Here’s the link on EMRR’s tip page for the general idea.

This method allows positive motor retention while nay havin' t' worry about t' hook gettin' in t' way o' the delay element when usin' t' AeroTech reload motors. Begad! Avast, matey, me proud beauty! I didn't use one o' t' three centerin' rings and changed the position o' t' upper centerin' rin' t' accommodate t' necessary position o' t' motor hook usin' a Dremel t' trim the upper end o' t' motor hook t' be level with t' top edge o' t' centerin' ring. Avast! Ya scallywag! T' instructions indicate t' attach the Keelhaul®©™® cord by wrappin' it around t' motor tube and insertin' t' end through a small hole in t' upper centerin' rin' then attachin' t' elastic cord t' a loop at t' end. However, I used me standard tri-fold shock cord attachment t' allow inspection o' t' shock cord. Avast! T' minimize abrasion from t' Keelhaul®©™® against t' body tube, I soaked in CA around t' top 1/2" o' t' body tube and tied a knot in t' Keelhaul®©™® to meet t' lip o' t' body tube.

I constructed t' entire rocket with yellow glue, arrr, ya bilge rat, usin' JB Weld for t' fin fillets. A markin' guide is provided for alignment o' t' fins and launch lugs. Arrr! Glue on t' launch lugs, install t' screw eye into t' nose cone (adding weight first t' compensate for t' largest motor you plan t' fly), and attach t' shock cord and you’re done as the parachute is already assembled. Avast, me proud beauty! T' parachute is very nice with small grommets holdin' on t' shroud lines.

Finishing:
T' balsa nose cone required very little finishing. Avast! With only a very light coat o' Elmer's Light Fill 'n' Finish, ya bilge rat, ya bilge rat, me bucko, the nose cone was very smooth. Avast! Avast, me proud beauty! Blimey! Only a light coat o' filler was also needed on t' fins, shiver me timbers, as t' basswood be very smooth after sandin' with 400 grit sandpaper. Begad! T' body tube was t' only thin' that required any significant effort-–darn spirals! Blimey! After usin' Fill 'n' Finish t' fill those and much sanding, I sprayed t' entire model with a light coat of Kilz t' seal off t' glue and provide a solid base coat. Avast! Next, arrr, I lightly sanded t' entire model with 240 grit sandpaper and then sprayed on a coat o' primer. Arrr! Ya scallywag! Blimey! Then, ya bilge rat, sand and primer and sand and primer again with 400 grit sandpaper. Arrr! T' nose cone and upper end o' t' tube was painted black and t' remainder was painted with Valspar’s Restoration Series Allis-Chalmers orange. Avast! Blimey! T' decals are large but applied relatively easily. Ya scallywag! Begad! Blimey! I didn't try movin' them around though, slidin' them off just where I wanted them. Avast, me proud beauty! I put a thick coat o' Future Floor Finish on t' protect everything.

Flight and Recovery:
First flight be on an Estes E9-6 with t' wind speed steady at about 5-8 mph. Avast! Begad! T' flight be perfect with ejection right at t' top. Well, blow me down! T' next flight was on an Estes D12-5, me bucko, and again, me hearties, t' flight be perfect with ejection right at the top even though winds had increased t' 8-12 mph. Ya scallywag! Recovery both times be perfect on t' 24 inch chute. I flew it on both motors again t' next day with t' same results. It was a beautiful day for flying, with winds rangin' from calm to 5 mph max.

Flight Rating: 5 out o' 5

Summary:
T' Super Javelin is another fantastic rocket from Hawks Hobby. Arrr! Parts quality is superb, me hearties, me bucko, and you can easily build the rocket in a few hours. Ahoy! T' rocket really zooms so if you decide t' go with higher impulse motors, matey, you'd better get ready for a long walk!

Overall Rating: 5 out o' 5
