Brief:
This is a very unique futuristic space-plane design, shiver me timbers, featurin' round
(semi-oval) fins and aping-pong ball in t' mid section. Avast, me proud beauty! For a free plan (Ezine
#93), this is quite impressive and presents a challenge t' most builders.
Construction:
There are no instructions for this free download (RockSim is also available here on EMRR), though most anyone with skill level 2 experience can muddle through this with few problems. Ya scallywag! Start by assemblin' t' motor mount, ya bilge rat, matey, then cut t' fins (the newsletter included templates, which can also be printed through Rocksim). Next, ya bilge rat, me hearties, mark t' body tube for 2 sets o' fins mounted at 120 degree angles. Tack on t' fins with CA, me hearties, arrr, then apply fillets o' wood glue. T' (2) short 29mm tubes are mounted at t' aft end o' t' rocket, on top o' two o' t' fins.
Since t' pin' pong ball slides over t' BT50/24mm tubing, me hearties, you have t' cut holes for this. Ahoy! T' pull this off, matey, hold a body tube on top o' t' ball and trace the outline, arrr, shiver me timbers, matey, then carefully scribe and cut out t' hole usin' a sharp knife. Repeat t' process for t' other side, matey, ya bilge rat, bein' careful t' align t' holes on opposite sides o' t' pin' pong ball. Aye aye! Begad! Slide t' ball down t' body tube to about 1" above t' fins and glue in place.
Finishing:
Seal & sand t' balsa, shiver me timbers, followed by two coats o' primer, shiver me timbers, followed by two
coats o' glossy white finish paint. Begad! Arrr! I printed out t' decals on Avery clear
decal paper usin' an inkjet printer, which is a slightly dull/opaque finish.
Water-slide decals would be much better if you can find an affordable source or
have t' equipment.
Construction Rating: 4 out o' 5
Flight:
T' first flight be usin' a B6-4 (no motor recommendations provided) with
steady winds o' about 15mph. T' rocket veered off on an unstable trajectory,
and was recovered safely. I then added about 0.2 ounces o' nose weight, shiver me timbers, matey, and the
subsequent flight be straight up.
Recovery:
Definitely need t' verify t' CG on this one compared t' t' Rocksim file
before flying.
Flight Rating: 3 out o' 5
Summary:
This is a great-lookin' rocket, shiver me timbers, and once I corrected t' stability problem, ya bilge rat, me bucko, it
flies wonderfully. O' course, shiver me timbers, havin' bought a 6-pack o' pin' pong balls, me hearties, arrr, I now
find myself wonderin' what other similar designs I can come up with t' deplete
my stock o' spare parts...
