About this Plan

Tiger (the Challenger). Free flight power model. Contest winner. From Air Trails Annual 1942.

Quote: "Speaking of women in aviation, this gas job, built by a girl, is the only beginner’s model we know of that is a contest winner. The Tiger, by Mary Louise Thomas.

Having won a class B motor, I was in the market for a plane to fit it. So I had my brother, HA Thomas, design me a simple, sturdy model and I built it, entered it in a contest and won first place in B Class. The ship also took first in Class B in our annual meet in Little Rock.

The model is quite conventional. Make a cardboard duplicate of the scale to facilitate enlarging the plans. The grid shown on the tail and wing tip will make them easy to enlarge. Hard balsa, pine or bass should be used for longerons, spars, wing edges, and softer balsa can be used for ribs, crosspieces, et cetera. The plywood pieces in the nose are reinforced below with pieces of 1/8 sheet on the inner sides. Veneer can be substituted for the sheet aluminum. Where the landing gear passes through the plywood, small plywood pieces should also be cemented on the inside as reinforcement. All ribs are cap-stripped above and below with 1/32 x 1/8 strips. The wing center section is covered with 1/32 sheet balsa.

The camouflage is easy to duplicate. Ivory is the background color, with gray-orange, gray-green and blue-black splashed in at random.

Test glide the model, moving the battery if necessary to balance. "

This is not a correction, but I wonder where the picture came from as I'm convinced that it's mine as it appears to be electric with an olympus gearbox. Is it covered in red nylon? I can only guess that the photo was taken at Middle Wallop in UK some years ago.

* 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.
