About this Plan

Kawasaki Ki-61 Hien (Tony). Radio control scale model Japanese WWII fighter.

Quote: "First off, let it be known that I'm not a 'dyed in the wool' scale builder, although I admire the work produced by that type of individual. The Kawasaki is my first entry into the scale field. After flying the usual competition and fun-type R/C multi-flying machines ie Ascender, Stormer (oz5794), Kwik Fli (oz6526), etc, I decided I wanted something different. That is, a scale R/C that would perform the full AMA pattern and look good while doing so. The Kawasaki-Mien (translated Flying Swallow) was the solution.

The Kawasaki KI-61, nicknamed 'Tony' by the Allies in WW II, was the only Japanese fighter powered by a liquid-cooled engine to see operational service. It was first encountered by the Allies over New Guinea in April 1943. Several versions of the aircraft were produced; the one presented here is the Kawasaki Type 3, Model 2A which was mainly used in the defense of Tokyo against the American B-29 raids. Although scale 3-view drawings are at a premium, I was fortunate to acquire considerable data on the Kawasaki from Volume III Warplanes of the Second World War, by William Green, published by Hanover House. Also, Dale Willoughby deserves recognition for providing me with additional scale plan data. The R/C plans presented herein are modifications of those supplied by Masahiro Kato in his Japanese kit of the same model.

The original model was completed and test flown one week prior to the 1966 Denver Mile-Hi R/C Club Contest. The ship placed first in R/C flying scale against some of the best looking scale R/C ships in the mid-west. Its flying characteristics were the deciding factor, since with a competent pilot and proportional, it will do all the maneuvers in the book and then some, ie fast application of up elevator equals high speed snap rolls! I discovered this startling characteristic on the initial test flight which was performed at the F'ikes Peak Radio Club Hying field at an elevation of 7.200 feet. Thereafter, I lengthened the elevator horn so as to limit the total elevator travel to approximately 1/2 inch. This is all the movement required, since the aircraft is relatively short coupled compared to present-day multi designs.

The equipment used in the original ship at the Denver contest was the F&M Propo-Digital 6. Frank Hoover's F&M servos, and a Merco-61 swinging a 12x6 Top Flite power prop. Insofar as the model presented here is concerned, it is almost fully scale; its wide landing gear, thick tapered wing and excellent aerodynamic qualities all contribute to truly outstanding flying characteristics.

Construction Details: Inasmuch as I loathe wing construction, I try to get this task out of the way first. WIng construction is similar to that used in other multi R/C's using all-sheet covered wings. First, laminate the 1/4 x 1/2 in balsa spars in the center section..."

    see Wikipedia | search Outerzone


    ScaleType: This (oz9047) 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/Kawasaki_Ki-61
    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.
