Waco Taperwing (oz9160)

About this Plan

Waco Taperwing. Radio control scale model biplane.

Quote: "I take a three view and start from there. This Waco is a modeller's dream for flying, whether the modeller is new at the game or an old seasoned flyer from way back when. The drawings I used for this plane were in the Air Classics of January 1975, and after reading the article and seeing the old bird all feathered out for racing, I just had to build it.

I used a conventional landing gear to simplify things, and took Jerry Nelson's construction ideas for the fuselage and tail assembly. This makes it easy to build and most importantly, holds down the weight.

As all the construction articles read: Construction of the fuselage is straight forward. I think what they mean is to start at the rear and work to the front and 'keep it straight.'

Cut the sheet balsa 'floor or shelf' and ink in the center line. Cut formers 2 through 6 and position on the center line. I use Wilhold or Titebond throughout, except as noted, and I find either to be quite satisfactory. The 3/32 sides are strengthened as shown on the plans with 1/32 ply. Contact cement used at this point will assure no war-page as might occur with other glues. The wing saddles (outer side) are also installed. Then the completed side panels are secured to the formers and shelf. After this has completely dried, we get to the firewall, then and then only.

I have found that on all biplanes I have ever built, which is more than I can remember, right-side thrust and down thrust never hurt a thing and sure can help an awful lot, so with that in mind, I want you to look at the assembly that you have tacked on the building board, place the center line of the firewall on the center line of the shelf and remembering the fuselage is upside down secure the lower right-hand corner of the firewall in position so that you end up with an actual right and down thrust of 1/8 back. That lower right-hand corner is going to show 1/4 in, and the top right-hand cornea, 1/4 in back, so that when the plane is in normal flying position you will have down and right-hand thrust of 1/8 in each, already built in for your firewall motor mount..."
