Quote: "N.A.A. XA2J SUPER SAVAGE NEO-DIMER
SPAN 16”
TWIN RUBBER POWER
Here’s another unusual aircraft that Gage Van Vranken requested and was unique enough for me as a nice twin rubber powered aircraft, and was only built in prototype form, never produced. North American Aviation was very much at the leading edge of aviation following WWII. This was meant to be an upgrade for the radial engined Savage.
Wing is build using the traditional solid balsa ribs 1/16” balsa sheet. 1/16”SQ upper and lower spars. I usually use the stack method of making the ribs, using a root pattern and tip pattern pinned together from each side and carved and sanded to shape. Remember there’s 3 root ribs W-1 then 2 ribs each for the other ribs.
Fuselage is built using the box style construction with 1/16” SQ longerons, uprights, and spacers. Using formers upper and lower on the fuselage for the top rounded shape. Canopy would be made using a flat sheet of acetate in the true dimer fashion. If you’re not competing you can vacuum form a canopy. I believe this plan would have to be published in some newsletter or magazine to actually qualify for a neo-dimer competition.
The empennage is all 1/16” SQ and sheet balsa.
Make the two nacelles as the fuselage is built, using the box technique. All using 1/16” sq and sheet balsa. The motor anchor is made by in-filling the triangle with 1/16 sheet balsa.
Here ya go Gage, hope this will work for you.
Once again I can thank Steve and Mary enough for hosting this site!!! Well Done!!!

ScaleType: This (oz16379) 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_XA2J_Super_Savage
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.

Thank you for the amazing plan. The super savage is one of my favorite aircraft in general. It really gives that flashy yet vintage appearance. After I finish my dumas sparrowhawk, this will be next.Gage Van Vranken - 09/11/2025

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.
