I started work on the X-Win' shortly after gettin' level 1 certification. Construction was based on a set o' plans I found on a Japanese website for a paper X-Win' model. Avast, me proud beauty! Blimey! From these plans, I was able t' create templates for t' X-Wing's fuselage bulkheads, ya bilge rat, wings, ya bilge rat, cockpit and nosecone. Construction began with t' purchase of a 38mm motor tube, a sheet o' 1/4" aircraft plywood and several 1/4" dowels. Well, blow me down! Avast, matey, me proud beauty! Blimey! I cut t' fuselage bulkheads from t' plywood, ya bilge rat, arrr, 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. Ahoy! 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. Blimey! Blimey! T' fuselage was then covered with cardboard. Aye aye! Blimey! After much fillin' and sanding, ya bilge rat, two wraps o' 6 oz fiberglass were applied t' t' fuselage. Avast, me proud beauty! Well, blow me down! Blimey! Holes were cut in t' bottom o' t' fuselage t' accommodate t' 1/2" copper pipe that would serve as t' launch lug. Arrr! Blimey!
With work finished on t' fuselage, matey, I began on t' wings. T' wings are constructed o' a basswood skeleton covered with a glassed balsa skin. T' engine fairings are build from cardboard reinforced at t' corners with basswood. Aye aye! Three different body tube sizes were used in t' construction o' t' wings. T' large motor tubes are 4" cardboard tubing, me bucko, t' aft "afterburners" are 2.6" tubin' and t' lasers on t' wingtips are made from 54mm motor tubing. Avast, me proud beauty! All tubin' be purchased from LOC Precision. Ahoy! When t' wings were complete, mounting holes were cut in t' fuselage. Begad! Win' are mounted through-the-wall; butted up to the motor tube.
T' nose cone and cockpit are built from t' same cardboard that was used t' cover t' fuselage. Well, blow me down! Again, templates were created from t' paper model plans. Begad! A 2.6" coupler was epoxied inside t' nosecone t' allow attachment t' t' fuselage. Well, blow me down! 2 lbs o' BB's and epoxy were added t' t' nosecone for stability. Avast, me proud beauty! Aye aye!
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, arrr, matey, bowls, milk cans, me bucko, ya bilge rat, etc. Aye aye! R2-D2 is from an old Estes mini-engine powered kit.
Durin' final assembly, me hearties, ya bilge rat, 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. Avast! All gaps were filled with an epoxy paste called PC-11. Well, blow me down! Avast! 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!), Testors Yellow and Krylon Red. Arrr! Ya scallywag! A mask was created t' spray t' "red five" pattern on t' wings. Begad!
With construction nearly complete, I began t' think about recovery. The finished model weighs in at about 13lb with motor installed. It be 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.
T' rocket flew at NYPower 11 on an Aerotech I-284 with 6 second delay. Begad! 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. Arrr! Besides, me hearties, 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. Ya scallywag! Well, blow me down! A brace be improvised usin' a piece o' body tube that was found near t' launch pad and some wire from used igniters. Well, shiver me timbers, blow me down! Takeoff was slow, and t' flight path be a gentle arc onto the rocket's back. Well, blow me down! Well, matey, blow me down! T' flight be 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 was a real nail biter with t' twin parachutes deployin' about 100' off t' ground. Ya scallywag! Avast! As expected, shiver me timbers, t' chutes were not sufficent t' prevent damage t' t' rocket. Begad! Two o' the "afterburners" were damaged, me bucko, one heavily. Begad! Begad! A split also occurred along the front o' t' fuselage, this may have been caused by t' premature separation, or t' plus-size ejection charge that was used t' ensure deployment. T' model is repairable. Blimey! Ya scallywag!
T' rocket was a real crowd pleaser. People seem t' like t' more unconventional models. Avast, me proud beauty! T' me knowledge it was t' only rocket at NYPower that got a cheer when t' chutes deployed. Arrr!
This be me first scratch built high power model, arrr, matey, and it was a great experience. Begad! Blimey! T' excitement is much higher when you are flyin' a model you built from scratch. Ahoy! Avast! I highly recommend givin' it a try. Well, blow me down!
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.
