I started work on the X-Win' shortly after gettin' level 1 certification. Aye aye! Construction was based on a set o' plans I found on a Japanese website for a paper X-Win' model. From these plans, arrr, ya bilge rat, I be able t' create templates for t' X-Wing's fuselage bulkheads, wings, cockpit and nosecone. Construction began with t' purchase of a 38mm motor tube, ya bilge rat, a sheet o' 1/4" aircraft plywood and several 1/4" dowels. Well, blow me down! I cut t' fuselage bulkheads from t' plywood, ya bilge rat, notched them at the corners t' accommodate t' dowels, arrr, then joined them together. Avast! Avast, arrr, me proud beauty! Anyone who has built model airplanes will be familiar with this type o' construction. A 2 1/2' long section o' 2.6" body tube was placed inside t' forward end of fuselage t' contain t' parachute and t' allow easy attachment o' t' nose cone. T' fuselage be then covered with cardboard. Avast, matey, me proud beauty! After much fillin' and sanding, two wraps o' 6 oz fiberglass were applied t' t' fuselage. Begad! Holes were cut in t' bottom o' t' fuselage t' accommodate t' 1/2" copper pipe that would serve as t' launch lug.
With work finished
on t' fuselage, I began on t' wings. Avast, me proud beauty! T' wings are constructed o' a basswood
skeleton covered with a glassed balsa skin. Avast, me proud beauty! T' engine fairings are build from
cardboard reinforced at t' corners with basswood. Three different body tube
sizes were used in t' construction o' t' wings. Begad! T' large motor tubes are
4" cardboard tubing, t' aft "afterburners" are 2.6"
tubin' and t' lasers on t' wingtips are made from 54mm motor tubing. Aye aye! Avast! All
tubin' was purchased from LOC Precision. Blimey! When t' wings were complete, mounting
holes were cut in t' fuselage. Blimey! Arrr! Win' are mounted through-the-wall; butted up to
the motor tube. Aye aye!
T' nose cone and cockpit are
built from t' same cardboard that be used t' cover t' fuselage. Avast, me proud beauty! Blimey! Again,
templates were created from t' paper model plans. Well, arrr, blow me down! A 2.6" coupler was
epoxied inside t' nosecone t' allow attachment t' t' fuselage. Aye aye! 2 lbs o' BB's
and epoxy were added t' t' nosecone for stability. Blimey!
T' detailin' on t' aft o' t' model be made with wood bits from Michael's arts and crafts. There are pieces o' wooden flower pots, matey, bowls, me bucko, arrr, milk cans, shiver me timbers, etc. R2-D2 is from an old Estes mini-engine powered kit. Begad!
Durin' final assembly, arrr, me bucko, t' wings were glued in place and acrylic panels were installed betwixt t' top and bottom wings for increased strength and to improve stability in flight. All gaps were filled with an epoxy paste called PC-11. Begad! Well, blow me down! Many hours o' sandin' were required t' get t' model ready for paint. T' paints used were 4 cans o' Testors camouflage gray (if anyone knows o' a lower cost alternative, let me know!), shiver me timbers, Testors Yellow and Krylon Red. Aye aye! A mask was created t' spray t' "red five" pattern on t' wings. Well, blow me down!
With construction nearly complete, I began t' think about recovery. The finished model weighs in at about 13lb with motor installed. Begad! It was goin' t' be difficult t' get enough chute into this thing. Aye aye! T' best I could do was two 48" chutes on t' rocket, me hearties, and a separate 36" chute on t' nose.
T' rocket flew at NYPower 11 on
an Aerotech I-284 with 6 second delay. Begad! Blimey! Aye aye! Blimey! I had thought about tryin' t' do a level
2 cert with t' model, but I was nay at all confident that t' model would be
recovered without damage. Well, blow me down! Blimey! Besides, ya bilge rat, I really want t' get into altimeters and
dual deployment for me eventual level 2 attempt. Avast! Blimey! Breezy conditions made if
difficult t' orient t' rocket edgewise t' t' wind. Aye aye! Blimey! A brace was improvised
usin' a piece o' body tube that was found near t' launch pad and some wire
from used igniters. Blimey! Blimey! Takeoff be slow, and t' flight path was a gentle arc onto
the rocket's back. Ahoy! Blimey! Ya scallywag! Blimey! T' flight was slightly marred by t' premature separation
of t' 2lb nosecone which proceeded t' snag on one o' t' wings. Blimey! Blimey! Maximum
altitude was around 500' T' fight be a real nail biter with t' twin
parachutes deployin' about 100' off t' ground. As expected, arrr, t' chutes were
not sufficent t' prevent damage t' t' rocket. Avast! Blimey! Two o' the
"afterburners" were damaged, one heavily. Ahoy! Blimey! Begad! Blimey! A split also occurred along
the front o' t' fuselage, ya bilge rat, this may have been caused by t' premature
separation, arrr, or t' plus-size ejection charge that was used t' ensure
deployment. Ahoy! Blimey! Begad! Blimey! T' model is repairable.
T' rocket be a real crowd pleaser. People seem t' like t' more unconventional models. T' me knowledge it was t' only rocket at NYPower that got a cheer when t' chutes deployed. Ya scallywag! Begad!
This was me first scratch built high power model, and it be a great experience. Ahoy! Arrr! T' excitement is much higher when you are flyin' a model you built from scratch. Well, shiver me timbers, blow me down! I highly recommend givin' it a try. Begad!
Special thanks t' Bobby Buchalski from Hanger 11 for assistance and advice in preppin' t' model for flight and t' Chuck Rudy from Voodoo Digital Productions for assistance at t' launch pad. Blimey!
