About this Plan

Big Bird Too - Radio control sport model. This is a low-wing version of the earlier RCM-810 Big Bird (oz5827) design.

Quote: - "The Big Bird Too is even more stable than the BB. The center of lift is natuarlly higher than on the BB but, due to the polyhedral, it is still above CG and we do not experience the pendulum effect as much as with the BB ...our approach is to combine low weight with generous wing area and a small throttle-equipped engine to obtain a forgiving, slow flying aircraft. This allows the new pilot ample time to correct his mistakes..."

Quote: - "Steve, Here is RCM's Big Bird II. It is the low wing version of the Big Bird high wing you have on Outerzone now. I built this plane about 20 some years ago, and it was a superb flyer. It would stay up all day with an OS 10 and 4 oz of fuel. Really good for thermals but not for high wind. I have it on my list to build again with electric motor. The title box of my original plan was town off and the large scanner chopped W1 W2 W3. A little measuring of the ribs on the wing plan with give the length. Thanks for the great service."

Note: this plan shows some distortion in the scannning at top right. If anyone out there has the skills and time available to clean this plan up and straighten it out, that would be great, thanks.

Update 26/09/2016: article pages, text & pics added, thanks to RFJ.

Update 20/04/2017: For an alternate clearer copy of this plan (no scanning distortion, more reliable) see the original Big Bird (oz5827) page which includes supplementary plan by hogal, which shows both versions of the Big Bird combined, in PDFvector format.

Update 03/05/2017: Replaced this plan with a clearer copy (removed distortion, redrawn from scratch) thanks to TonyP.

Quote: - "Some months ago I downloaded Big Bird Too ID 6220. I didn't bother to book it as it was very badly distorted and needed a complete redraw, was going to take a long time, and I was'nt certain how original I could make it look. In fact it's come out fine. However, I see that Hogal has done one of his fine jobs on it and beaten me to it. My fault of course but I have attached it anyway. "

User comments

I've been eagerly waiting for somebody to post the Big Bird II. Regarding the distortion in the scan and the missing rib tips, I read the construction article on another website, which said that the wing was exactly the same as the original Big Bird because they were too lazy to build another one. If a good scan of the Big Bird II can't be had, a really ambitious person could simply cut and paste from the other plan to replace every distorted part. I'll see if I can talk my son into doing that. He's not a model airplane nut, but he loves working with photoshop.

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.
