About this Plan

Madman. Control line stunt model. Wingspan 49in, wing area 429 sq in, for Orwick .64 engine.

Designed by JC Yates. Plan drawn by Howard Johnson.

Note photo of completed Madman model was found online at

There is an interesting snippet in the AMA JC Yates bio at which is an extract from the Charles Mackey book 'Pioneers of Control Line Flying', published 1995, as follows:

"JC lives in Hemet, California. He has a large workshop next to his house that is full of Radio Controlled airplanes. He does not fly competition, but still designs, builds and flies model airplanes. Two points that should be raised: one, JC has no memory of charging his airplane dry cell batteries and thinks it is a foolish idea and two, the 'Madman' plans drawn by Hi Johnson do not show 1/4-square-inch wing spars and show more dihedral than the 1947 National airplane."


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

Dear Mary and Steve, I hope everything is going well for you. I found this advertisement [pic 004] for the Burbank Manufacturing, JohnsonBilt , “MADMAN” by J.C. Yates. This was found in the May 1948 Air Trails Pictorial Page 96. My father James K Jolly worked for Mr Howard Johnson in 1953 when he moved his manufacturing from Burbank to Fullerton California. The Company also had a name change to “Ken Hi Products”. As Ever,

* 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.
