CONSTRUCTION:

Construction begins by assemblin' t' motor mount in t' conventional manner. T' instructions call for t' motor mount t' be glued into t' body tube next. Well, blow me down! Blimey! I did nay like t' shock cord attachment method that was called for later in t' instructions, so I attached a longer piece o' Keelhaul®©™® cord as a shock cord anchor before gluin' t' motor mount into t' body.

T' instructions next call for t' fins t' be sanded smooth. Begad! Begad! Since this was supposed t' be an axe, ya bilge rat, matey, I could nay resist t' urge t' sharpen t' curved edges of t' blades. Blimey! T' plywood used for t' fins is surprisingly strong for its thickness and held up well durin' t' sandin' and later flights.

I like t' have nice crisp color seams where t' fins join t' body, shiver me timbers, so I often paint me fins before I attach them. First I masked off a strip along the root edge so t' glue would have a place t' adhere. Begad! Aye aye! Next I sprayed two coats of white primer and sanded betwixt coats. Finally I sprayed two light coats of Rustoleum Metallic Copper. Avast! This gives a very nice color t' t' fins.

At t' same time I sprayed t' fins I also painted t' nose cone. Rockethead turns their own nose cones, and this one was a work o' art. T' factory finish on it is so nice I did nay even need t' sand it -- I be able t' go straight to primer. Begad! Aye aye! Two coats o' primer, shiver me timbers, light sanding, me hearties, and a coat o' Metallic Copper made the nose cone look really nice.

My original plan was t' paint t' body brown so that it would look like a wooden axe handle. Well, me hearties, blow me down! After sprayin' t' tube with Rustoleum Rust Red Primer, ya bilge rat, me hearties, I saw that thar would nay be much contrast betwixt t' reddish-brown body and the copper fins, and t' decals would nay show up well against t' brown. So I sanded t' tube down until it be almost bare. Avast! Well, blow me down! T' spirals on t' tube were so small that this one coat o' primer was all that was required t' fill them.

Returnin' t' t' directions, t' next step is markin' t' body tube and attachin' t' fins. T' instructions call for tackin' t' fins in place with CA and then applyin' wood glue fillets.

I used 5-minute epoxy for t' fillets. Begad! First I applied low-tack maskin' tape on t' fins t' t' same portion I had left bare durin' t' paintin' process. Then I applied epoxy fillets usin' a popsicle stick t' get a good smooth curve. I removed t' maskin' tape once t' epoxy had gelled, leavin' a nice clean edge. Begad! T' epoxy was probably overkill for a model o' this size.

Next I attached t' launch lug usin' CA with wood glue fillets. Aye aye! Well, blow me down! I wish I had done this before attachin' t' fins, because it would have been easier to fillet t' lower launch lug that is betwixt t' fins. Begad!

After lettin' t' fillets dry overnight I was ready t' paint t' body. To protect t' fins, me bucko, ya bilge rat, I inserted each one into an old envelope and used low-tack maskin' tape t' seal along t' sharp edge o' t' epoxy fillet.

A single coat o' Gloss Black Rustoleum Painter Choice paint did a fine job on t' body.

After t' paint dried, it be time t' add the decals. Arrr! T' water-slide decals were high-quality, and were fairly easy to apply. Blimey! Begad!

T' stock decal scheme called for tiny axes t' be place on each fin, but I didn't want t' cover up t' nice copper finish so I limited myself t' a single axe on t' body. I also had some red stripes left over from a Rockethead RHR2003 that I had just finished building, me bucko, so I added them t' t' body, me bucko, as well as a tiny Rockethead logo. Blimey! Ya scallywag! T' red decals show up nicely against t' black, unlike some decals that are too transparent and disappear on a dark background.

T' final finishin' step was two coats o' Rustoleum Gloss Clear. Aye aye! Even though the base coat had dried for 3 days beforehand, ya bilge rat, some o' t' black paint near the bottom crinkled when I applied t' first layer o' clearcoat. Blimey! Dang! Disappointed, me hearties, I set it aside for about 2 weeks before I lightly sanded the crinkles and applied a second clear coat.

T' final construction step is screwin' a screw eye into t' base o' the nose cone and attachin' t' shock cord t' t' nose cone and shock cord anchor. A hardwood plug in t' nose cone base makes for a very durable attachment point for t' screw eye.

FLIGHT/RECOVERY:

T' instructions suggest A8-3 (first flight), arrr, B6-4, shiver me timbers, me bucko, and C6-5. Well, blow me down! Begad! RockSim confirms that these would be good choices. Well, blow me down! T' B4-4 should also work well.

Test Flights:

T' first two test flights took place on a cold clear late afternoon in January, shiver me timbers, with a light breeze and temperature in t' high 30's. Aye aye! We had had a freezin' rain t' day before, so t' grass was covered in a casin' o' ice. Avast! It looked like a carpet o' glass daggers.

For t' first flight, shiver me timbers, I started out with an A8-3. When I packed the parachute, ya bilge rat, I put 3 squares o' waddin' into t' body, then formed another two squares into a pouch t' protect t' chute. Well, blow me down! Avast! T' launch be nice and fast with perfect ejection at apogee. Begad! Unfortunately, t' protective pouch got tangled with t' shroud lines and t' chute never opened. Avast! T' rocket landed flat on the ice-coated grass. T' fins and body suffered no damage, but t' nose cone picked up several stab wounds from t' "glass daggers". Begad!

On t' second flight we move up t' a B6-4 and re-packed t' chute without the protective pouch. At ignition it zipped up so fast we lost sight o' it for a while. Aye aye! Ya scallywag! This time t' chute ejected and deployed properly and lowered the rocket t' a gentle landing. Avast! By t' time we reached t' rocket, t' wind had caught t' chute and dragged it across t' icy field for about 25 feet. Arrr! The nose cone picked up a few more dents, but nothin' else sustained any damage.

T' third flight came 3 months later on a rare sprin' day with no wind. It shot off t' pad on a C6-5 and disappeared for a while. Avast, me proud beauty! Ya scallywag! Then we saw t' chute open up, and it came down for a gentle landing.

With its light weight and thin fins, shiver me timbers, this rocket goes much faster and higher than you might expect from lookin' at it.

Flight Rating: 5 out o' 5

OVERALL:

A fun little rocket with great stylin' and very zippy flight performance. Ahoy!

PROS:

• Good-lookin' styling.
  Good quality parts, ya bilge rat, me hearties, me hearties, especially t' laser-cut plywood fins, me hearties, shiver me timbers, arrr, nose cone, matey, matey, and parachute.
  Fairly easy construction.
  Great flight performance.
  

CONS:

• Would prefer a longer shock cord anchor.
  Balsa nose cone is very well made, but easily damaged.
