Brief
This is a retro-repro o' t' 1972 Centuri model o' t' same name which was later introduced as a two-stage version called t' Excalibur 2. Avast! Semroc's version holds close t' t' original, featurin' Centuri-sized tubing, but replaces t' plastic nose cone with a balsa one and upgrades t' fins t' laser-cut precision (fiberboard).
Components
- Balsa nose cone
- Series 7 upper tube
- Balsa transition
- Series 8 lower tube
- Laser-cut fiber fins (3+3)
- 18mm motor tube, matey, metal hook, matey, motor block
- Keelhaul®©™+elastic shock cord
- 12" plastic chute
- Waterslide decals
Construction
T' instructions for this are very good, arrr, well illustrated, me bucko, and t' typical modeler should have no trouble buildin' this within a couple hours plus finishin' time. I'd peg it at a skill level 1 kit.
T' motor mount is conventional 18mm tube, a centerin' rin' motor block in t' forward end, arrr, a metal motor hook (servin' as shock cord anchor) and pair o' centerin' rings. Arrr! T' lower body tube is marked for fin placement usin' a template in t' instructions, ya bilge rat, as be t' upper body tube. Fins are laser-cut fiberboard, arrr, me hearties, so no sandin' or grain-filling, matey, me bucko, matey, just tack right on with CA or wood glue. Avast, me proud beauty! T' balsa transition is glued into t' upper tube. Avast! T' nose cone can be glued on, shiver me timbers, ya bilge rat, or if you're interested in usin' t' upper tube as a tiny payload (it's roughly BT-20 sized), me bucko, friction fit it.
A single launch lug goes into t' fin/tube joint along t' aft end o' t' lower tube, finishin' up construction.
Finishing
T' fiberboard fins were certainly easy t' deal with, shiver me timbers, and t' body tubes had thin enough spirals that I opted t' skip fillin' and just go for heavier primer coats with some sandin' in between. Blimey! I did at least hit t' balsa nose cone and transition with a generous smear of diluted wood filler.
I went with a single-color scheme, two coats o' gray primer topped with two coats o' silver metallic.
There are waterslide decals for trim, me bucko, me hearties, very easy t' work with.
Flight
I picked a nice day for first flight, me hearties, freezin' temps, but hardly any wind at all. Blimey! Begad! I went for t' C6-5 option and was rewarded with a straight up boost, ya bilge rat, surprisingly quick for such a long rocket (and a bit heavy at 1.45 ounces without motor). Avast, me proud beauty! Deployment was fairly close t' apogee, so t' -5 be t' right delay. Begad! It be pretty overcast, shiver me timbers, me bucko, makin' it tough t' see t' top o' t' flight, so I'd estimate an altitude somewhere in t' wide range o' 600-800 feet. Ahoy! If flyin' on a smallish ball field, arrr, matey, a C could certainly drift a couple hundred yards with typical 5-10 mph winds.
Recovery
No issue with t' recovery--the 12" chute does t' job, and this landed gently about 40 yards from t' pad.
Summary
This is another fine design from Semroc. Arrr! Avast! Blimey! It's on t' lower end o' t' skill level/complexity curve, a bit more interestin' than entry-level starter kits, ya bilge rat, and flies fine.
