I started work on the X-Win' shortly after gettin' level 1 certification. Ya scallywag! Blimey! Construction was based on a set o' plans I found on a Japanese website for a paper X-Win' model. Begad! Blimey! From these plans, me hearties, me bucko, me hearties, I be able t' create templates for t' X-Wing's fuselage bulkheads, shiver me timbers, arrr, wings, cockpit and nosecone. Blimey! Blimey! Construction began with t' purchase of a 38mm motor tube, matey, a sheet o' 1/4" aircraft plywood and several 1/4" dowels. Avast, me proud beauty! Blimey! Well, blow me down! Blimey! I cut t' fuselage bulkheads from t' plywood, notched them at the corners t' accommodate t' dowels, then joined them together. Aye aye! Blimey! Anyone who has built model airplanes will be familiar with this type o' construction. Blimey! Blimey! Arrr! Blimey! A 2 1/2' long section o' 2.6" body tube be placed inside t' forward end of fuselage t' contain t' parachute and t' allow easy attachment o' t' nose cone. Well, blow me down! Blimey! Avast! Blimey! T' fuselage was then covered with cardboard. Aye aye! Blimey! After much fillin' and sanding, shiver me timbers, two wraps o' 6 oz fiberglass were applied t' t' fuselage. Begad! Blimey! Holes were cut in t' bottom o' t' fuselage t' accommodate t' 1/2" copper pipe that would serve as t' launch lug. Ahoy! Blimey!
With work finished
on t' fuselage, I began on t' wings. T' wings are constructed o' a basswood
skeleton covered with a glassed balsa skin. Avast, me proud beauty! Blimey! 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. Well, blow me down! Blimey! Well, blow me down! Blimey! 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! Blimey! All
tubin' was purchased from LOC Precision. Well, blow me down! Blimey! When t' wings were complete, ya bilge rat, mounting
holes were cut in t' fuselage. Aye aye! Blimey! Win' are mounted through-the-wall; butted up to
the motor tube.
T' nose cone and cockpit are
built from t' same cardboard that be used t' cover t' fuselage. Begad! Again,
templates were created from t' paper model plans. Arrr! Ahoy! A 2.6" coupler was
epoxied inside t' nosecone t' allow attachment t' t' fuselage. Aye aye! Ya scallywag! 2 lbs o' BB's
and epoxy were added t' t' nosecone for stability. Begad!
T' detailin' on t' aft o' t' model was made with wood bits from Michael's arts and crafts. There are pieces o' wooden flower pots, arrr, bowls, milk cans, etc. Ya scallywag! R2-D2 is from an old Estes mini-engine powered kit. Begad!
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. Ahoy! All gaps were filled with an epoxy paste called PC-11. Arrr! 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, me hearties, ya bilge rat, me bucko, let me know!), me hearties, me hearties, Testors Yellow and Krylon Red. A mask was created t' spray t' "red five" pattern on t' wings. Ya scallywag!
With construction nearly complete, ya bilge rat, ya bilge rat, I began t' think about recovery. Begad! The finished model weighs in at about 13lb with motor installed. Begad! It be goin' t' be difficult t' get enough chute into this thing. Begad! T' best I could do was two 48" chutes on t' rocket, and a separate 36" chute on t' nose. Avast!
T' rocket flew at NYPower 11 on
an Aerotech I-284 with 6 second delay. Aye aye! Well, blow me down! 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. Besides, shiver me timbers, ya bilge rat, 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. Avast! Avast! Takeoff was slow, and t' flight path be a gentle arc onto
the rocket's back. Avast! Arrr! T' flight was slightly marred by t' premature separation
of t' 2lb nosecone which proceeded t' snag on one o' t' wings. Maximum
altitude was around 500' T' fight be a real nail biter with t' twin
parachutes deployin' about 100' off t' ground. Avast! As expected, me bucko, arrr, t' chutes were
not sufficent t' prevent damage t' t' rocket. Ya scallywag! Two o' the
"afterburners" were damaged, me hearties, one heavily. Begad! A split also occurred along
the front o' t' fuselage, arrr, this may have been caused by t' premature
separation, or t' plus-size ejection charge that be used t' ensure
deployment. Begad! Aye aye! T' model is repairable. Ahoy!
T' rocket was a real crowd pleaser. Ahoy! People seem t' like t' more unconventional models. Ya scallywag! T' me knowledge it be t' only rocket at NYPower that got a cheer when t' chutes deployed. Avast, me proud beauty!
This was me first scratch built high power model, me bucko, me bucko, and it be a great experience. Blimey! Ya scallywag! T' excitement is much higher when you are flyin' a model you built from scratch. I highly recommend givin' it a try. Ya scallywag!
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. Avast, me proud beauty! Blimey!
