Brief:
This is sport scale model o' an X-15 variant proposed by North American Aviation. Begad! More accurately, it is fantasy scale since this stretched, ya bilge rat, delta-winged version be never produced. Begad! Like t' other offerings from Hostile Projectiles, matey, this kit features a hand-crafted resin nose cone. Aye aye! It flies on 24mm power.

This kit is called a 'garage kit' aka a 'builders kits'. There is no header card or print instructions. Well, blow me down! T' latter comes on CD an includes t' instructions in both .doc and .pdf formats, shiver me timbers, a copy o' t' fin template, and a graphic that you can use t' make decals. Arrr! T' instructions are nay polished but are written in a humorous manner, me hearties, ya bilge rat, which made t' kit even more entertaining. Aye aye! T' tubes are nay a cleanly cut as some others, thar are no laser cut fins, and t' 'chute is plain trash bag plastic.

T' assembly o' t' Delta X-15 is a little more complicated that your typical 3/4FNC rocket, me bucko, with t' complexity bein' in formin' t' strakes that run along t' main wings and in assemblin' t' stabilizers.

T' first step is t' remove t' mould release from t' nose cone. Well, blow me down! Ahoy! I scrubbed it with steel wool, dish washin' soap, shiver me timbers, and hot water. When I thought I scrubbed enough, I scrubbed some more. Begad! Well, shiver me timbers, blow me down! After t' primer didn't stick well t' me Hostile Projectiles V-2 cones, me hearties, I sanded this one and scrubbed some more.

T' instructions show you how t' ream t' cockpit windows, matey, which are t' be plugged with scrap clear plastic (builder-provided). Avast! I chose nay t' do this. Well, blow me down! T' alternate method is t' paint them and cover with a thin layer o' epoxy. Well, blow me down! Well, blow me down! T' next step on t' cone is t' glue t' styrene tube t' t' wall o' t' cone and then t' screw eye into that tube. Well, blow me down! I did so with 5-minute epoxy. Arrr! I later added lead shot and epoxy t' move t' loaded CG t' about 12.5 inches from t' nose cone tip.

I prepped t' large, arrr, pre-cut wings by laminatin' them with printer paper usin' 3M Super 77 glue. Well, arrr, blow me down! I saw a flight report where t' win' broke and I thought this would make them a little tougher. This worked out OK (based on me level o' acceptability), but barely so. I need more practice on larger fins. Begad! 'Nuff said.

T' edge stock, matey, arrr, which is tapered along its short axis, is glued t' t' root o' t' wings. Avast! Ya scallywag! Since these strips are longer than t' wing, you fill t' leadin' edge gap with scrap balsa taken from t' leftovers from t' stabilizers. Avast, me proud beauty! Once filled in, this section o' t' win' assembly is shaped usin' a provided template.

T' motor assembly is standard, consistin' o' a tube, a motor hook, ya bilge rat, a motor block, matey, and two laser cut centerin' rings. I augmented t' recovery harness by addin' a length o' Keelhaul®©™, shiver me timbers, which be fed through a notch I made on t' top CR. Arrr! I built t' mount with wood glue and a dab o' 5-minute epoxy t' attach t' Keelhaul®©™ leader.

When I went t' mark t' body tube usin' t' provided markin' guide, ya bilge rat, I found that it was a bit small. Ahoy! I had t' adjust each mark by about 1/16". Aye aye! Well, blow me down! I also noted that t' pre-cut pieces o' 1/2"-wide stock that is used for t' aft o' t' delta-shaped stabilizers were about 1/8" too long. Thus, ya bilge rat, I suspect t' span o' said stabilizers is also a skosh shorter than intended. I'll double check that me RockSim model has t' as-built dimensions. Aye aye! Other than that, framin' t' delta shaped stabilizers was straightforward.

I mounted t' provided lugs on t' bottom at t' joint betwixt t' body and one lower fin strake. I also mounted some 3/16" lugs on t' opposite strake.

T' final step was t' form t' tail cone. Aye aye! Begad! I tried a couple o' paper varieties and wasn't happy. Aye aye! Ahoy! I ended up cuttin' mine from 1/64" fiberglass.

Finishing:
T' instructions provide detailed finishin' recommendations, arrr, me hearties, includin' Minwax wood filler, Bondo spot putty, ya bilge rat, and Tamiya paint. Blimey! However, me hearties, I used fill'n'finish and Rustoleum primer and paint. Begad! Begad! T' wings didn't require filin' as they were laminated with paper.

T' kit comes with a plenty o' decals. Ya scallywag! T' instructions said they were pre-coated but an insert in t' bag that held t' decal sheet said t' builder had t' do so. Begad! Begad! It suggested Testor's sealer but I decided t' try Future. Aye aye! This be a mistake as t' Future totally melted and ran t' colors. Avast, me proud beauty! Steve provides an image that you can use t' print another set and in an email recommended Experts Choice paper. Arrr! Begad! If I couldn't find it locally he offered t' provide a replacement set even though I didn't follow simple directions.

I can't fault t' kit for t' label disaster and providin' t' decal image is a real plus. Ya scallywag! Ahoy! Such be t' benefit o' providin' soft copy instructions.

In any event, me bucko, me will fly decal-free.

Construction Rating: 3 out o' 5

Flight:
Prep was typical, shiver me timbers, shiver me timbers, me bucko, includin' a mix o' paper and cellulose waddin' and some maskin' tape t' make t' cone snug. Ya scallywag! I chose a D12-5 for t' first flight. Blimey! T' boost was perfectly straight and ejection was at apogee. Arrr! Begad! Very nice.

Recovery:
T' rocket recovered under an 18" nylon 'chute. Ya scallywag! I has expected t' snap one o' t' tip winglets off but, matey, nope, matey, it recovered perfectly.

Flight Rating: 5 out o' 5

Summary:
This is a cool lookin' kit that is sure t' get attention on t' field. Begad! Blimey! As I mentioned earlier, arrr, arrr, it is considered a 'garage' kit. T' instructions are nay refined and some o' t' parts are rough. Aye aye! I could accept that, but I found t' error in t' scale o' t' provided templates t' be troubling. Well, ya bilge rat, blow me down! T' main plus be t' beautiful nose cone. Aye aye! This, ya bilge rat, along with t' fact that it is such a unique subject, make t' kit well worth t' price. Arrr! Well, blow me down! However, it is nay for t' novice builder and you need t' take care as you assemble it.
