Brief:  This is a nice mid-power kit. I used it for my L1 cert. A single stage bird that recovers via 'chute

Construction:  This kit is pretty straight forward. It was the first HP type kit that I had built so I did not understand the instructions real well at first in regards to the "LOC-type" attachment in the body tube for the shock cord mounting. Other than that the kit goes together easily and is well suited for the beginner. The through-the-wall fin mount allows for ease of alignment of the fins. The parts of the kit were all in good shape and fit properly one to another.

Finishing:  The kit is the basic rocket shape so finishing can be a breeze. With a little more time and effort I could have removed the "spiral" that we see so often in kits where the paint is just sprayed on after the body assembly is completed.

Construction Rating:   3 out of 5

Flight:  I flew this puppy on a H grade motor every time. the flights were Clean and straight. I used approximately 4 handfuls of the gray insulation for heat shield for the 'chute it worked well. With both single use and reloadables motor retention can be accomplished with tape for the SUs or Kaplow type kits for the reloadable. Both are easy to incorporate into the airframe.

Recovery:  The only headache with flight recovery is that the bird is light enough that it will drift quite a distance on the stock chute. I would suggest trying it with stock and then maybe downsizing one size to reduce those long walks

Flight Rating:   3 out of 5

Summary:  Over all a very good Kit. Perfect for the beginner and an acceptable quick build for the more experienced builder.

Brief:
The Javelin is a single stage 29mm rocket with a nice sleek 3 fin design.

Construction:
The Javelin comes with a nice set of directions and LOC-type 2.56" tubes, 62" total length. Three G-10 fins for through-the-wall construction are provided. The rocket has a good size payload section which could easily house an altimeter although I didn't build it that way. Plywood bulkheads and centering rings are provided and are good quality. A steel eye bolt is provided for the upper bulkhead to attach the shock cord to. A good length of elastic/braid shock cord is provided as well as a piece of nylon cord for a shock cord attachment loop. A nice long plastic nose cone is provided and fits nicely with the overall sleek outline of this kit.

Instructions provided are good for an experienced builder and a nice overall engineering type drawing of the rocket is provided. Nice if you have to re-build any of the rocket from some flight mishap! A straightforward build makes a sturdy kit. I added two "T"-nut motor retainers on the rear centering ring since I am not a fan of "tape" motor retention.

This was to be my Level 1 rocket so I took my time and did a thorough job of fin fillets using a mix of milled glass with 20 min. epoxy. This was my first G-10 fin rocket and I was careful to sand the fins with 150 grit sandpaper where the fillets would be to make sure good adhesion was obtained with the epoxy.

Finishing:
Pretty much standard finishing, tube spiral filling required. I painted my rocket with a bunch of primer coats, primarily to fill those spirals! Then gave it a bright yellow paint job with a black gloss nose cone and hornet like stripes coming down the upper part of the airframe, it looks cool!. No decals were included.

Flight:
My first flight with this rocket was my Level 1 and I chose an H128 White Lightning RMS motor. The launch was straight and fast! It went ~2100' (based on the Rocksim simulations).

My next flight was with another H-128 and this time things went sour, a failed delay insulator caused a motor burn-through when the thing was ~150' up. This zippered the upper airframe but the rest of the rocket was intact despite a free fall without a chute from 150'. I cut out the damaged section, added a coupler and a new segment of airframe and it was ready to go again.

The next flight was on a G75 Black Jack, one of my favorites. This was a really nice moderate speed flight that went ~2200' (see photo).

Recovery:
Nylon 24" purple chute that is just right for the rocket. I would down-size if I was putting an I200 in the thing so I would get it back, it's a light rocket (28oz).

Flight Rating: 4 out of 5

Summary:
Nice sleek sturdy kit that flies great.
