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