About this Plan

Com-Bat. Control line combat model for .35 power.

Quote: "'Wings' are quick on the draw but sometimes too tricky for their own good! For 35's, this job is easy to build and fly. Right CG, control set-up, for stability. Com-Bat, by Earl Cayton.

Com-Bat is an extremely simple to build combat and sport model which is fun to fly, yet having a novel appeal which sets it off from other present day combat craft. Construction is super simple. With the cowl and distinctive paint job you have a model that is a real eye catcher on any flying field. Without the cowl and painted trim construction time is at a minimum and building time is reduced to one evening to replace combat losses at contests. Ruggedness is another virtue of the Com-Bat.

To add a change of pace to combat run of the mill models, a J Roberts bellcrank unit can be used in conjunction with the new K&B Torpedo .35 with throttle control. With engine speed control, an astute combat flier can add new tricks to his combat strategy. If variable engine speed is not desired, any large control horn, such as Veco, may be used. Also, any .25 to .35 displacement engine will power the Com-Bat very nicely.

Fuselage: The fuselage is basically the profile type which is simple to construct. The profile is simply cut from a sheet of rock hard balsa stock size 2-1/2 x 1-1/2 x 14-1/2 in. The 1/8 plywood sandwiched on each side of the profile suffices easily for the engine mounts. The engine is mounted with four #4-40 bolts. Put a fairly thick washer between the engine and mounts at the front mounting bolts. This will provide some out-thrust to insure the model staying tight on the lines at all times. After you have chosen a good commercial tank, or constructed your own pet design, mount it in position with rubber bands. Do not mount permanently until wing is installed.

Wing: The wing also is simple. First cement a strip of 3/16 x 3/8 pine to one edge of a sheet of medium balsa 2 x 3/8 x 30 inches which is a combination leading edge and spar. This pine leading edge helps protect the wing leading edge from the frequent bashing in incurred during combat events. The trailing edge and tips are formed from 3/8 x 1-1/2 in sheet. Ribs merely consist of 1/8 x 3/4 in balsa strips. This doesn't form any super airfoil of any sort, but it makes for quick easy construction and flight characteristics are good which is what really counts..."

Quote: "Hi Steve & Mary, Here is another C/L model from the 1950s that was a lot of fun. I'm a sucker for anything a bit different. Striking colour scheme, but the wing is a bit thin. I built a couple with a thicker, 'proper' symmetrical airfoil and they flew much better. Unfortunately I only have the first page of the article, and I cannot find the photos of my Com-Bats, so I have cleaned up one of the page 1 pics. My first Com-Bat looked exactly like this. Cheers, KraftyOne."

I had forgotten about the red highlights in the eye and mouth. The rest of the model was always B & W. Here it is in "Full Colour" [more pics 003]. The underside was usually plain black with red or white club and association markings.

* 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.


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.
