About this Plan

Crazy Crate. Simple all-sheet tethered-line biplane sport model. For .020 power.

Quote: "If you're one of those fortunate individuals with an old K&B Infant engine or you know someone who is no longer using his, then Crazy Crate is your dish. This little crackpot is a tether line job, which means that it flies by itself on the end of a single guide line with no controls.

The full-size plans will enable you to produce the Infant size in a jiffy; for larger engines just double all measurements. Attach the tether wire to a mounting bolt and run it out through the dowel. This serves as a guide. The model should be balanced along this line.

To fly, hold one end of the flying wire; have your mechanic start the engine. Just hang on and allow the model to take off by itself. It will as it picks up speed. Because the center of gravity is so far ahead of the wing. the wing acts like a stabilizer during flight, preventing pitching.

Keep your Crate as light as possible. Dope it with, clear, then spray on fuel proofing."

* 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.
