B-24 Liberator (oz4533)
About this Plan
B-24 Liberator. Radio control scale WWII bomber, for 2 x .049 engines and 2 or 3 channels. Wingspan 62 in, wing area 360 sq in.
Quote: "This is an 'economic' 4-engine model. Only two 1/2A engines, diesel or glow, are needed to pull this 2-3 channel ship. B-24J Liberator, by Eric Clutton
The B-24 was faster, had more range and carried a bigger load than the B-17 but had looks only a mother could love and was a much more demanding plane to fly, requiring a lot of extra effort in the all important formation flying compared to the B-17. So why model a B-24? Apart from it hav-ing a high wing and a boxy fuselage, making it easier to model, I had a couple of other reasons. I used to work on RAF Coastal Command Libs in England during WWII and the area where I now live in Tennessee was a hotbed of B-24 training bases. I was determined to have the first B-24 to fly over Tullahoma in 50 years!
I had also determined that using four engines added a lot of weight and would require a much larger model than I was comfortable with. So I chose - for reasons of economy and simplicity - to use two en-gines on the model. I also figured that once the model was airborne it would not be possible to tell it only had two engines instead of four.
Construction. Fuselage and tail. Start by making left hand and right hand side frames from 1/8-inch sheet balsa, edging with 1/4-inch square balsa. When cutting out the sides it is possible to use the piece cut from under the rear end to make up wood required on the top side of the rear. The 1/4-inch square should be cracked or cut at each change of direction, not bent to a curve.
The sides can now be assembled using the formers. If the tops and bottoms of the for-mers are fitted as separate pieces this makes it easier to maintain a square and true assembly.
Top and bottom keels are now added and the lower section covered with sheet as noted on the plan. The 1/32-inch ply section is to take care of any landings on hard stuff! The 1/16-inch sheet is easily sanded to blend in with the 1/32-inch. Joints between sheets should be made so the butt joint is midway on the former.
Servos, pushrods and all that stuff should be sorted out at this point before completely covering the top with balsa sheet. If the horizontal stab is made it can be fitted and the various pushrods linked up. The elevator is only fitted to one side and is basically for trim purposes. My model made a good few flights as two-channel with only rudder and throttle control but elevator now allows me to flair out after a glide approach..."
Note this is a low resolution plan.

ScaleType: This (oz4533) 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/Consolidated_B-24_Liberator
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.

* 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.
