About this Plan

Avions Caudron. Quarter Midget racer, based on the 1936 Thompson Winner. Wing area 340 sq. in, airfoil NACA 65010.

Quote: "Steve, Please find attached a scanned plan of my old Hal Debolt 1/4 midget of years past. I thought the plan was long lost, but found it after two moves in a bunch of RC stuff, also long lost. All the info is on the plans including the NACA airfoil used. If I remember correctly the wing was a pain to build the way it was laid out using the three support jigs. If I had it to do over, I would cut a foam wing and be done with it. Our modern RC gear will more than make up for the extra weight. Mine came out light enough I was forced to use a 500ma battery to make weight. It was glassed with 3/4 oz glass cloth and epoxy, painted with DuPont lacquer paint. It was a VERY nice flying plane with no bad habits."

Did we get something wrong with these details about this plan (especially the datafile)? That happens sometimes. You can help us fix it.

    ScaleType: This (oz6378) 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
    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.

Hi Steve & Mary. This plan only shows the root rib profile. Doesn't show the rest of the ribs, or at least the tip rib so the rest can be interpolated or a foam core wing cut. I'm I missing something or should it be labeled as incomplete?

Ok, thanks have set this one as incomplete now.

The tip rib is the same airfoil as the root rib. You would just need to shrink the root rib to fit the tip. On my example the tip has a slightly more blunt leading edge.

* 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.
