T' parts list:
T' downloaded plan set includes images o' t' printed material from t' original kit, me bucko, It includes additional photos o' t' collection o' kit parts, t' round balsa parts, t' flat balsa parts, ya bilge rat, and an aftermarket part sheet that describes part details and dimensions for a win' segment. Begad! T' photographs give a good idea what each part should look like. Arrr! This is quite important for t' round parts because none o' these parts are off-the-shelf items. Aye aye! Well, me bucko, blow me down! T' original kit printed instructions include an exploded drawin' o' t' entire model, me bucko, a set o' assembly drawings, arrr, me hearties, and step-by-step instructions for each assembly drawing. T' instructions are quite clear, shiver me timbers, and t' assembly drawings illustrate what needs t' be done in each step fairly clearly, however, shiver me timbers, me hearties, t' assembly drawings are generally nay drawn t' scale.
There are some serious "gotcha's" with t' downloaded plans that must be taken care o' durin' initial parts fabrication. Ahoy! Well, blow me down! First, t' descriptions o' t' "blow-out plug" in t' round-part photo and in t' aftermarket parts list specify a taper that cannot work. T' forward end o' t' plug must taper t' 1", NOT 0.75"! This is because t' elevon hold-downs mounted on t' plug must straddle a BT-50 tube, NOT a BT-20 tube. Blimey! Second, ya bilge rat, t' lengths o' t' BT-50 and BT-55 body tubes are possible, but they can't yield t' model shown by t' original kit insert or in t' Kopter catalog (found at Sven Knudson's Ninfinger website). Begad! From assembly figures 5 and 14, me bucko, t' correct BT-50 and aft BT-55 tubes can be deduced t' be 14" long, arrr, NOT 18". Avast, me proud beauty! Ya scallywag! From t' model specs and figure 5, me hearties, t' forward BT-55 tube must be 11" long, ya bilge rat, NOT 8". Avast, me proud beauty! Begad! Third, shiver me timbers, t' dimensions for Win' Part A on t' aftermarket parts list are nay consistent. Begad! That is, thar are too many dimensions and they don't add up. Ahoy! I recommend disregardin' t' 10-5/16" dimension while keepin' t' others.
I used a plastic "toy lathe" t' turn t' balsa nose cones, baffle plug, shiver me timbers, and blow-out plug. Begad! Begad! T' lathe is a Toymax Toolmaster Workshop that, shiver me timbers, unfortunately, arrr, has been OOP since around 1997. Without a lathe, you should be able t' order t' nose cones and baffle plug from Balsa Machinin' Services. Blimey! T' blow-out plug should be doable too, arrr, if you figure out t' dimensions t' specify.
Instead o' usin' 3" wide flats, arrr, I used 4" wide balsa flats for t' wings and rudder. Blimey! Begad! T' do this, I drew t' full-scale outlines o' t' completed win' and rudder, based on given patterns, then divided them up into 4" strips. Ahoy! I feel that this lead t' simplified assembly by reducin' t' number o' joints that needed fittin' together.
Once all o' t' parts had been fabricated, followin' t' assembly instructions be straightforward but still posin' some interestin' challenges. Matchin' duct slots had t' be cut into different caliber 14" tubes, ya bilge rat, arrr, then had t' be carefully sealed together with glue joints and fillets. T' win' and rudder parts needed careful trimmin' for precise fit.
