Brief:

This is a free plan downloaded from Apogee's newsletter E-zine web site (issue #91). Aye aye! It's a very nice, shiver me timbers, basic modroc, which I'd rate at about a skill level 2-3. Blimey! It features two sets o' fins, with t' larger set mounted Forward o' t' smaller set for an unusual appearance.

Construction:

T' Parts List comprises:

• 24mm nose cone
• 24mm (BT-50) tubin' 13.5"
• 18mm motor mount kit with 18-24mm centerin' rings
• 12" parachute/shroud lines
• Shock cord (1/8" elastic at minimum, I used 1/4")
• 1/8" launch lug
• 1/8" balsa or basswood fin stock (I used balsa)
• Clay for nose weight (about .25 oz)

There are no instructions provided with this free download, arrr, but its basic design is easy t' assemble if you've got some previous experience. Begad! Avast, ya bilge rat, me proud beauty! If you have t' full version o' Rocksim, shiver me timbers, you'll want t' print out t' fin patterns, ya bilge rat, as this is much easier than drawin' them from t' dimensions.

Construction is fairly simple. Well, blow me down! Start by makin' a motor mount out o' 18mm tubin' with a couple o' centerin' rings. Optionally use a metal engine hook, me hearties, though I use friction fit on 18mm motors, matey, so went without t' hook. Aye aye! Mount t' motor mount in t' BT50, cut out t' fins, tack usin' CA, fillet t' seams with wood glue, shiver me timbers, install t' recovery device, matey, and add enough nose weight t' get t' CG about 10.5" from t' nose o' t' rocket.

Finishing:
T' Shrox design depicts a two-tone red on white paint scheme, includin' white tips on t' mostly red fins. I went with that approach, and also added a basic decal "SNIPET" for identification (printed on me inkjet with Avery clear decal paper).

Construction Rating: 4 out o' 5

Flight:
There were no recommended motors, me hearties, so I played around on Rocksim and came up with A8-3, matey, matey, B6-4, me hearties, and C6-5 as t' best motors. Well, arrr, blow me down! First flight was with a B4-4 on a day with steady 15mph winds. Avast! T' rocket weathercocked a bit, but otherwise flew very well. Arrr! Blimey! I suspect I went a bit heavier than necessary with t' nose weight, shiver me timbers, matey, as I was a little conservative flyin' a "plan" instead o' a "kit". Begad! Avast, me proud beauty! T' delay be slightly early, though I think movin' t' a 6 would have been a bit late. T' rocket was recovered safely with no damage, and is now sittin' in me ever-growin' box o' Shrox/Apogee plan birds.

Recovery:
Nay t' best rocket for a windy day, me hearties, I'd back off on t' nose weight or fly under 10mph winds.

Flight Rating: 4 out o' 5

Summary:
My only suggestion for improvement would be a simple decal or two for a better overall appearance.
