About this Plan

Cessna 170. Radio control scale model for .25-.35 engines, designed by Henry Struck. 1954 Berkeley kit. Wingspan 72 in. Scale is 1/6.

The plan includes build instructions text.

Quote: "This replica of the Cessna 170 has been designed to provide the ultimate in realistic performance. In fact, at 6 lbs gross weight the model is considered dynamically similar to the full scale ship when carrying the pilot, and will behave in the air like the big ship.

To make this high performance model practical, the structure has been designed with great care to withstand the high air loads and hot landings to be encountered. Therefore this is not a model to be assembled in a hurry. Study the plans and detail sketches before beginning work to become familiar with the general construction. Since all the details are illustrated in the plan these instructions are necessary only as an outline of construction. To further simplify assembly have been numbered in the order of installation, and with the letter F denoting fuselage, W wing, S stabilizer and R rudder..."

Update 12/07/2019: Added wing ribs, thanks to Edubarca.

Quote: "These are the full size wing ribs for this beautiful balsa model of a classic airplane. As was usual in 1954, no wing ribs were drawn on the plan because it was designed and drawn for a kit. You can see that I attached the supports on the ribs that state 'jig' after the identification number, this facilitates building the wing with no warps. Good luck and greetings from Colombia. EDUARDO".

Did we get something wrong with these details about this plan (especially the datafile)? That happens sometimes. You can help us fix it.

    ScaleType: This (oz681) 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.

    ScaleType is formed from the last part of the Wikipedia page address, which here is https://en.wikipedia.org/wiki/Cessna_170
    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.

This is my Cessna 170 using the Berkeley plans [model photo & more pics 003]. I modified them to 5 channel radio and installed a vintage Super Tigre .35 engine for power. This is the same engine I had in my original Cessna single channel built in 1956.

* 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.
