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