About this Plan

Cessna L-19 Bird Dog. Rubber scale model.

Update 08/10/2018: Replaced this plan with a re-scaled version, thanks to rchopper56.

Quote: "This is the best I am willing to do without putting the file into cad. There are still discrepancies in that the ribs are a little too big and the bulkheads a little too small. This is truly a measure 3 times, cut once file."

Direct submission to Outerzone.

Note: this plan seems to have been drawn up from the original Frog Cessna Bird Dog (oz10509) plan.

    ScaleType: This (oz4424) 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/Cessna_O-1_Bird_Dog
    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.

User comments

It appears that the scaling is off on this plan. The parts are larger than the working drawing. Interestingly this plan seems to be the author's attempt to rework the FROG model #731 FK with additions of a better nose block, 1/32 wing ribs, a built up rudder, etc. FROG models are great but they tend to be rather robust and are just ripe for modification and weight reduction and that seems to be the attempt here. The original FROG plan was 22" and this is 20" as it is now. For reference and verification see the web site for House of FROG.

The web address is http://www.houseoffrog.co.uk/ I believe it appears under their heading of "Rubber powered scale models".

* 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.
