Information:

The plans have been modified slightly to bring it up to newer building standards, including eliminating the blocks of wood for the motor mount and replacing them with a standard motor mount. This allows a wider variety of power plants, including electric. None of the changes affect the final plane, they just make it a little simpler to build.

Here are all the changes:

1.  Changed to a solid firewall, with standard motor mount. As a result of this, I straightened out the nose of the plane, so it is easier to build, and there will be no problem fitting or cooling any engines/motors. Most people changed this when it was scratch-built anyway.

2.  The firewall is set to 2 degrees right thrust, and 2 degrees down thrust, so the engine is at the proper angles automatically.

3.  The 3/16″ balsa nose doublers are cut to automatically place the firewall at the proper location and angles. The left and right sets are different, so the left side set will be marked on the wood.

4. The 1/16″ PLY landing gear braces are replaced with 1/4″ braces to make the gear mounting stronger.

5. The center of the wing has been modified. The 1/4″ center rib that had to be tapered by sanding to match the dihedral is gone. The inner ribs of each wing have been changed to 3/16″ balsa, and a precut dihedral gauge is supplied so they can be installed at the proper angles, so the wing halves will fit together easily, at the proper dihedral. The alignment dowels are still used.

6. The wing ribs have both building tabs for accurate building without a wing jig, and 1/4″ holes for use with a wing jig.

   The kit is available with either a foam wing or a built-up wood wing.
