CURTISS P-40Q-3
27” SPAN RUBBER FF
DRAWN BY TOM AKERY 23 OCT 2025
There are tons of P-40 Warhawks out there but very few P-40Q-3’s. I was looking for a warbird to draw and even though this bird was to late for WWII, it was to be the ultimate P-40 variant. Even though there were 7-8 variants there were only 3 prototypes. The first two prototypes were just two airframes built from existent P-40K and P-40L airframes. The final P-40Q-3 got the latest Allison engine with two stage superchargers that was still in development. There’s a nice article on these prototypes found on this link on the Old Machine Press: https://oldmachinepress.com/2015/08/18/curtiss-xp-40q/
Wing is constructed using the Dave Rees’ Sliced Rib Technique, link found on plan to the tutorial by Mike Stuart.
Fuselage has all the formers/bulkheads cut from 1/16” sheet balsa and built using a Ladder Jig. The tutorial for this is noted on the plan of Tom Hallman’s Beechcraft Twin Staggerwing video: https://www.youtube.com/watch?v=1yUYY1dqfH8
The empennage has the outline of the horizontal stab made with 3 laminations of 1/32”x3/32” outline and 3/32”SQ and sheet balsa spar and ribs. The vertical stab outline is 3 laminations of 1/32”x3/32” with two 1/16” vertical spars and 1/32”x1/8” outer ribs. There are two basic color schemes for these aircraft. The first was in the standard Olive drab finish and the second was in the overall bare metal finish.
Have not built this model yet but hope you’ll note any errors. I hope you can find this as a nice addition to your squadrom.
Regards,
Tom Akery/Sky9pilot"

ScaleType: This (oz16394) 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/Curtiss_P-40_Warhawk
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.
