About this Plan

Millibar. Radio control aerobatic model for .29 to .45 power.

Quote: "An attractive 'smaller size' aerobafic model with a sparkling performance for .29 - .40 site motors...
Like Mike Birch I like to read of the development of other people's models. However (I cannot tell a lie) this model was developed for me. Look closely and you will see that it is none other than Phil Kraft's Bar-Fli (oz5544) in disguise. After building two Bar-Flis I decided I liked the layout generally but did not like the 'built-in drag' approach since it limited the performance in certain manoeuvres. About this time, I decided that I wanted a model to practice pylon course flying. This model was, preferably, to be the same size and weight as a Goodyear (Formula 1) racer.
It was then discovered that scaling the Bar-Fli down to nine-tenths full-size gave a wing area of 470 sq in; the stage was thus set for thr Millbar. It was decided to mount the motor on its side andclaen up the front end. The cockpit was moved forward to give the fashionable fish look. There was avery sound aerodynamic reason for doing this - I needed somewhere to stow the DEACs on my bulky Diditrio-4!
The resulting model turned out to be a much better aerobatic model than I ever expected. Its competition results have been limited more by my flying ability that its own failings, although things have not been helped by a motor in pylon racing trim rather than a proper aerobatic motor..."

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

* 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.
