About this Plan

Waco E. Radio control scale model biplane.

Quote: "Hi Steve, Here is Ken Willard's Waco E from Model Builder magazine issue 11-84. The text describes this as an updated R/C version of his earlier plan which is posted as Waco (oz1585)."

Quote: "WACO Biplane, by Ken Willard. Finally! Here's a fun little biplane designed for the G-Mark .030 that will fly and look realistic in the air or on the ground. Grab some sheet balsa and your micro radio gear!

About twenty five years and thirty pounds ago, I designed a small, all-balsa and plywood Waco Custom Cabin biplane for the Cox Tee Dee .020 engine, an Otarion super-regen receiver, and Babcock escapement. The Waco (oz1585) design was published in the now defunct American Modeler magazine, and was popular with small airplane enthusiasts. After a couple of years of flying, the model was 'retired' to hang in my garage.

A couple of years or so ago (the pounds had stabilized by then), I took the Waco down, cleaned it up, and installed a new radio and engine combination. The radio was Cannon's Super-Micro, and the engine was the G-Mark .030. It was the perfect combination; the throttle feature on the G-Mark made it possible to taxi out, take off, climb out, throttle back and cruise - even do touch-and-goes! It was a reborn hit.

I took some photos of it with me when I went to the Toledo show in April 1983, and showed them to Bill Northrop, originator of the phrase: Real airplanes have round engines and two wings. How about an updated construction article? I'll do it. Time passed, other designs came along. Then I went to Toledo in April 1984, Bill gave me that icy stare. I'm working on it, I lied. When'll I get it? Bill demanded. Before the end of May. What year? He had me trapped. This year, I promised.

So here it is. When you see it, if it's late in the fall, don't blame me. I did what I promised - delivered it in May, 1984. Yeah, I shoulda done it sooner, but there's a side benefit now. In addition to Cannon, you can also install the new, lightweight equipment from World, Airtronics, Circus, or Ace. The choice is yours. There's room for any one of them. The plans show a schematic installation for three servos, a small receiver, and a small battery pack. The servos are in-stalled merely by sticking them to the sides of the fuselage with mounting tape, and the receiver and battery pack are loosely packed in foam rubber and stuffed up front behind the firewall.

With the exception of the radio mounting, the basic construction is unchanged from that which was described twenty one years ago. This is the way it read:

WINGS. The top and bottom wings are made in three pieces - the right and left panels and the center sections. The panels are butt-joined and glued to the center sections, with the inboard ribs of the panels slanted at the proper angle to provide the right dihedral. Some sanding may also be required to make the angle accurate. Then a 1/2in strip of nylon, or Celastic if you prefer, is glued over the joint on the top and bottom to give it the necessary amount of strength.

To make the panels there are a couple of tricks. Let's take a top panel in sequence.

1. Lay the bottom sheet of 1/16, sanded to 1/20, on a flat surface.
2. Put a piece of 3/16 sq stick under the bottom surface, longitudinally, at the tip rib location. Pin the bottom sheet to the table.
3. Trim the bottom of the leading edge to fit the curve from the tip rib to the next inboard rib. Glue in place..."

    ScaleType: This (oz4664) is a scale plan. Where possible we link scale plans to Wikipedia, using a text string called ScaleType.

    If we got this right, you now have a couple of direct links (above) to 1. see the Wikipedia page, and 2. search Oz for more plans of this type. If we didn't, then see below.


    Notes:
    ScaleType is formed from the last part of the Wikipedia page address, which here is https://en.wikipedia.org/wiki/Waco_E_series
    Wikipedia page addresses may well change over time.
    For more obscure types, there currently will be no Wiki page found. We tag these cases as ScaleType = NotFound. These will change over time.
    Corrections? Use the correction form to tell us the new/better ScaleType link we should be using. Thanks.

Notes

* Credit field

The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.

Scaling

This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
