About this Plan

Ultimate Biplane 40. Radio control biplane sport model for .40 engines.

Discontinued kit from Great Planes.

As requested on the wanted page.

Quote: "The Great Planes Ultimate 40 is a high performance, propeller-driven sport biplane that closely resembles the full size Ultimate. The Ultimate 40 is very stable and forgiving, allowing even intermediate skill level pilots to enjoy it.

This is not a beginner's airplane! While the Ultimate 40 is easy to build and flies great, we must discourage you from selecting this kit as your first R/C airplane. It lacks the self-recovery characteristics of good basic trainers such as the Great Planes PT Series. On the other hand, if you have already learned the basics of R/C flying, and you are able to safely handle a 40-size low wing airplane, the Ultimate 40 is an excellent choice to try your skills at flying a biplane.

Engine selection: There are several engines that will work well in your Ultimate 40. We recommend a hot 2-stroke such as an OS .40FX or SuperTigre G45 with a Pitts style muffler. For unsurpassed power and realistic sound, an OS FS-52 4-stroke can't be beat. The engine you select will determine how you build the firewall section, so it is important that you have the engine close at hand while building..."

    ScaleType: This (oz13254) 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/Ultimate_Aircraft_10_Dash
    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.
