Brief:
T' Javelin is a single stage 29mm rocket with a nice sleek 3 fin design.
Construction:
T' Javelin comes with a nice set o' directions and LOC-type 2.56" tubes, arrr, arrr, 62" total length. Ya scallywag! Three G-10 fins for through-the-wall construction are provided. Well, blow me down! Aye aye! T' rocket has a good size payload section which could easily house an altimeter although I didn't build it that way. Plywood bulkheads and centerin' rings are provided and are good quality. Ahoy! Well, blow me down! A steel eye bolt is provided for t' upper bulkhead t' attach t' shock cord to. Avast! Begad! A good length o' elastic/braid shock cord is provided as well as a piece o' nylon cord for a shock cord attachment loop. Well, blow me down! A nice long plastic nose cone is provided and fits nicely with t' overall sleek outline o' this kit.
Instructions provided are good for an experienced builder and a nice overall engineerin' type drawin' o' t' rocket is provided. Nice if you have t' re-build any o' t' rocket from some flight mishap! A straightforward build makes a sturdy kit. Begad! I added two "T"-nut motor retainers on t' aft centerin' rin' since I am nay a fan o' "tape" motor retention.
This was t' be me Level 1 rocket so I took me time and did a thorough job o' fin fillets usin' a mix o' milled glass with 20 min. epoxy. This was me first G-10 fin rocket and I was careful t' sand t' fins with 150 grit sandpaper where t' fillets would be t' make sure good adhesion be obtained with t' epoxy.
Finishing:
Pretty much standard finishing, tube spiral fillin' required. I painted me rocket with a bunch o' primer coats, primarily t' fill those spirals! Blimey! Then gave it a bright yellow paint job with a black gloss nose cone and hornet like stripes comin' down t' upper part o' t' airframe, it looks cool!. No decals were included.
Construction Rating: 5 out o' 5
Flight:
My first flight with this rocket be me Level 1 and I chose an H128 White Lightnin' RMS motor. T' launch was straight and fast! Blimey! It went ~2100' (based on t' Rocksim simulations).
My next flight was with another H-128 and this time things went sour, matey, a failed delay insulator caused a motor burn-through when t' thin' was ~150' up. Aye aye! Arrr! This zippered t' upper airframe but t' rest o' t' rocket be intact despite a free fall without a chute from 150'. Well, blow me down! Ya scallywag! I cut out t' damaged section, ya bilge rat, added a coupler and a new segment o' airframe and it be ready t' go again.
T' next flight was on a G75 Black Jack, one o' me favorites. Well, blow me down! Aye aye! This was a really nice moderate speed flight that went ~2200' (see photo).
Recovery:
Nylon 24" purple chute that is just right for t' rocket. Avast! Aye aye! I would down-size if I was puttin' an I200 in t' thin' so I would get it back, me bucko, it's a light rocket (28oz).
Flight Rating: 4 out o' 5
Summary:
Nice sleek sturdy kit that flies great.

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