About this Plan

Quote: - "Your tool for boring holes in the sky! Used by author: 10x7in prop on 1000Kv motor using 4S 5000mAh. Use 5S for 800Kv motor."

Quote: - "A couple years ago I designed a 40-size sport plane around some equipment and wood I had on hand. The intent was to have something with which I could just bore holes in the sky, so I called it the Drill Bit 40. With size and power comparable to my electrified Tower Kaos 40 it was sure to be a winner, but what I didn't realize right away was how many others liked it. It is a simple design, but not a 'box' - I wanted something that required a little extra craftsmanship just to make it different."

Quote: - "Hi Steve, Here are final plans for the Drill Bit 40 as found in the build thread at
https://www.rcgroups.com/forums/showthread.php?2632298 Thanks for making your plans site available. Andy"

Notes

* 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.

Scaling

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.
