Sperry Monoplane (oz4657)
About this Plan
Sperry Monoplane. Rubber scale model. This is a modern re-drawn plan.
Quote: "Hi Steve, This is my first direct submission. The Sperry Monoplane by Jed and Trudee is scale rubber powered free flight. The wing span is 20". I do not know when it was designed but has a copyright of 1967 [confirmed now]. This plan was for a very long time, distributed by Peck Polymers which is now A2Z corp. It is no longer available from A2Z corp ...I find the model very attractive and it is definitely a very good flyer. I have over the years, made two or three at peanut scale. They never failed to do 30 seconds minimum when kept below 8 grams. The first one built, did an out of sight after about 90 seconds. The second one was carried away by a creek. The third died from hanger rash. This model will not disappoint the builder if kept light and no warps. I have used these relationships for some of my own originals with good success. The enclosed file was generated in cad but it is not a vector file. It was exported as a tif from the original PDF file so as to add a border and then save with G4 compression. The result is a smaller file but it is now a raster."

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 (oz4657) 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/Curtiss_JN-4
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 commentsHi Steve, Don't know if you want to post this or not, but I took your Outerzone Sperry Monoplane 20" rubber plan (ID#: 4657) and printed it at 200% to give me a 40" span outline. I then redrew the plan and built a 3ch. electric. Since there aren't a lot of photos of the original, I did it up in a sort of British WWI scheme. She's powered with a Firepower Speed 400, 30amp ESC on an 1800mAh (3s) Lipo. She's still a hanger queen at this time, but with a wing loading of only 11.25 oz/sq.ft., I expect she'll fly fine. Thanks for all you do to keep this hobby alive.

Nice work. Since I have no pic of this model at 100%, will happily use this as the main model pic for now. Thanks

The dates are correct on the plan. This was designed by my mother and father then sold to William Hannon. I've asked my father several times over the years. I just recently (July 2020) had 3 laser cut short kits made for my father, myself and daughter. Hopefully I'll have some new photos to submit in the near future. I intend on making mine a 3 channel electric park flyer.

* 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.
