Rocket PicBrief:
Any 'rocket scientist' will immediately recognize t' similarity betwixt the SHX-15 and t' actual X15 rocket plane. Arrr! I assume t' new name just absolved Shrox from keepin' t' scale. Arrr! This cool rocket flies on 24mm motors, and is made from top-notch materials.

Modifications:
Recovery harness upgraded and Launch lug relocated, matey, as described below. Well, blow me down! Avast!

Construction:
T' kit came bagged in clear plastic, with all t' small components in their own zip-lock bag. T' instructions are brief, with clear illustrations. However, arrr, matey, shiver me timbers, t' instructions for t' shock cord were unclear and deviated from the parts list. Aye aye! Well, matey, blow me down! Blimey! More about this later. Begad! Blimey! One thin' did concern me - t' decals were missing. There be a note enclosed that said they were backordered and would be provided later. Arrr! Ya scallywag! Blimey! It also gave a URL where t' decal sheet can be downloaded. Ya scallywag! Arrr! Blimey! I am hopefully optimistic that these will eventually show up, but you won't see me holdin' me breath. Arrr! Avast, me proud beauty! Blimey!

As I said, t' components are o' above average quality. Avast! Arrr! T' 13" BT-55 tube is thicker than t' Estes tubing. Avast, me proud beauty! T' motor mount consists o' a section of BT50, matey, ya bilge rat, me hearties, an engine block and two nice thick centerin' rings. Begad! T' chute is 12" Nylon, arrr, and t' recovery system includes 13" o' Keelhaul®©™® twine and a 13" section o' ¼" elastic. Begad! This is smartly becoming my favorite combination for small modrocs. Ya scallywag! Blimey! T' fin stock is good quality 3/32" basswood. Avast! Begad! T' remainin' components include t' plastic nose cone, a standard launch lug, clay nose weight, ya bilge rat, an Estes-style shock cord mount, and a card stock cockpit cutout.

Followin' t' instructions, I first built t' motor mount. Ahoy! In case I wanted to use t' new Estes E9, ya bilge rat, I replaced t' 24mm tube with a slightly larger piece. I went ahead and used t' motor block, arrr, and will need a spacer for a D12. Avast, me proud beauty! Avast, me proud beauty! I also drilled a hole in t' front centerin' rin' for attachment o' t' Keelhaul®©™® tether.

Shrox SHX-15 T' fins have to be cut from t' basswood stock. Ya scallywag! I was pleasantly surprised how easily the basswood cut. Aye aye! It was nicer than t' stock I have bought from hobby stores. Ahoy! Begad! The instructions included two copies o' t' fin patterns, me bucko, and thar be more than enough wood provided. I hate it when every bit is used up - I'm sure t' screw somethin' up in that case. There be no fin markin' guide, me hearties, ya bilge rat, but it is easy to make one and do your own marking. Blimey! T' large wings consist o' 3 pieces and are first glued together on a flat surface. Arrr! A sheet o' wax paper insured they did not gunk up t' kitchen counter. Aye aye! Begad! T' side fins are attached at a -20 degree angle from t' wings, shiver me timbers, so I made a small paper triangle t' make sure I got this angle right. Ahoy! Arrr!

As I said, matey, arrr, t' instructions for t' shock cord assembly were unclear and did nay match t' parts list. Oh well, I did things differently anyway. Begad! First, I added a piece o' 500 lb Keelhaul®©™® the length o' t' body tube. Ahoy! One end is fed through t' hole I drilled in the centerin' ring, tied off, me bucko, and glued. T' other end is tied t' t' provided Keelhaul®©™® tether, which was in turn tied t' t' elastic cord. Ahoy! Ahoy! Thus, t' elastic will be well removed from t' hot ejection gasses. Ya scallywag! T' nose cone came with t' plastic hook removed. Avast, me proud beauty! Arrr! Evidently, Shrox felt that this would be too weak given t' nose weight required for stability. Since it would be tough t' feed t' elastic through t' small hole provided in t' nose, I also added a few inches of Keelhaul®©™® twine as a leader. Arrr! Blimey! I installed one snap swivel where t' lower Keelhaul®©™® tether is connected t' t' elastic cord, shiver me timbers, me hearties, and t' other is attached t' the chute. Ya scallywag! Well, this was probably more than you ever wanted t' know about a simple recovery harness.

I had problems with t' last two steps. T' card stock cockpit caved in' slightly at t' ends as it dried - a minor issue, matey, ya bilge rat, as it still looks fine. Aye aye! Next, the instructions say t' glue t' launch lug t' t' underside o' t' side wing at its root edge. However, t' rear, me bucko, angled fins will block t' launch rod if the lug is in t' prescribed location. I double-checked t' fin installation and it is correct, ya bilge rat, so t' options were t' move t' lug away from t' body tube, or put it on t' top side o' t' wing. Avast! I did t' latter.

Finishing:
I went all-out on t' paint, arrr, shiver me timbers, usin' purple/green Duplicolor Mirage. This stuff goes on in three steps: a black undercoat, t' color coat, shiver me timbers, and a clear topcoat. T' results look fantastic if I do say so myself! I will add t' decals if they ever show up.

Construction Rating: 3 out o' 5

Flight: Shrox SHX-15
T' instructions did nay indicate a recommended motor, but t' web site says a D12-7. Avast, me proud beauty! When I was goin' t' check if this model was in t' EMRR recommended motors database, I noted that t' recommended motors were t' C6-5, and C6-7. Well, thar must have been a previous version that had an 18mm motor mount. Anyway, this got me thinking, ya bilge rat, ya bilge rat, and despite t' fact that I went insane and planned for an E9, I decided t' use an adapter and try a C6-5 for t' first flight. Blimey! T' model boosted well and weathercocked quite a bit (the wind be 5+ mph). Arrr!

Recovery:
Recovery was nominal and thar was no landin' damage.

Flight Rating: 4 out o' 5

Summary:
I have always loved t' X15, matey, and really like this kit. Begad! It is a little more challengin' than a 3/4FNC rocket. Arrr! There were several minor problems with the instructions and t' decals were missin' (and still haven't been delivered). Aye aye! In the end, shiver me timbers, me advice is this: if you really love t' looks o' this rocket, go ahead and buy it. Aye aye! T' quality o' t' materials is good and you will end up with a great addition t' your fleet.
