About this Plan

North American P-51 Mustang. Radio control scale model WWII fighter, for electric power using Speed 400 motor.

Quote: "The Electric P-51 Mustang. Speed 400 powered P-51A (and A-36), P-51B and P-51D. Designed and drawn by Gus Morfis.

The story of the P-51 Mustang has been told a good many times already and this article could add nothing new. Suffice it to say that this was the Allied fighter which was finally able to successfully escort and defend our bombers against the German interceptors, on the long road to their targets and back.

The name 'Apache' was given to the earliest airplanes, but this quickly gave way to the now famous '"Mustang.' The earliest model was the A-36 and it was to be a ground attack airplane. The P-51A was really the same airplane, except that it was optimized for the fighter role, and the most prominent differences were the change in armament and the deletion of the wing mounted dive brakes.

In service, it quickly became apparent that its Allison engine was rated for medium altitude performance and that Allison-engined airplanes could not operate effectively at much over 16,000 ft altitude. The same thing happened to the Bell P-39 Airacobra. But the Lockheed P-38 Lightning escaped this problem because its Allison engines were turbo supercharged. The rules of war had changed and altitude capability in the 25,000 ft. range was now required.

The Allison engine could not be adapted for this new altitude environment, but the British Rolls-Royce Merlin engine could. And it was agreed that these engines would be built in the U.S. by the Packard motor car company. These airplanes were identified as P-51 Bs. This change altered its thrust line and its nose contours. In addition, the belly radiator also had to be enlarged and revised to match the requirements of the Merlin engine.

These changes improved the P-51B's altitude performance and now its range was unmatched as an escort fighter. The P-51B was now a significant player in the war.

The next change was to develop the Mustang to its final, classic shape. A bubble canopy was fitted in order to improve its all around vision, and the designation was now P-51D.

The plan gives the details required to make any of these versions. My partner in this project is Jack Hix, who also did the photography. Our model used a direct drive Speed 400 motor and seven KR600AE batteries. After doing a lot of flight testing and having a lot of fun with his Mustang, Jack then tried the more powerful Astro Flight 020 motor, but this proved to be just too much power for this model.

Jack first used aileron and elevator control only, and he was very pleased with the Mustang's handling. But then he added the rudder and the model was even more fun to fly. So, you choose the set-up that you prefer to use.

Construction. This is a small model, so be weight alert, and select quality wood for your construction. Also, prior to beginning construction, cover the plans with waxed paper or plastic wrap to prevent the glue sticking the parts to the plans.

Wing: Note that all four versions of this airplane have the same basic wing, but only the A-36 Apache's wing has the four 20mm cannon armament. Locate lower sheeting, lower spar cap, lower 1/32 x 1/2 trailing edge strip, the lower 1/32 x 1/4 capstrips, and glue in place. Taper, chamfer and glue in place the leading edge and the trailing edge doubler as required. Locate the wing ribs as shown on the plans and angle rib #1 per the dihedral template, then glue in place..."

    see Wikipedia | search Outerzone


    ScaleType: This (oz8150) 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/North_American_P-51_Mustang
    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.
