About this Plan

Brooks Biplane - Free flight gas model. With 66in wingspan it is for 2.5cc to 3.46 cc motors.

Update 10/02/2013 : Added PDFvector (and also CAD) version of this plan, thanks to hogal.

Quote: "Basil Brooks was the designer and flier of the Biplane. The model had been developed over four years until the stage at which the plans were published. It looks a really interesting and practical build and was even suggested as being suitable for R/C in 1952. It is an interesting design and one that would be well worth building nowadays - especially considering that, according to the article, it meets the pre-1950 deadline. The recommended minimum power is an ED 2.46 Racer with a preference towards a 3.46cc motor ...I think I would tend to start with a OS 40 FS and consider a OS 26 FS after initial flights. However with three channel RC it would give a sweet summer evening treat. As always with my drawings they are only tracings from the original articles and may be subject to faults ...If you do build from my plans please take care and measure at least twice before applying the knife. Most of all - enjoy."

Update 07/02/2017: Turns out this plan is 66in not 56in wingspan. Thanks to Brian for pointing this out. Will sort out resizing the files asap.

Update 09/02/2017: Replaced this plan with a better version (for now) at correct scale, with wingspan 66in, thanks to Edubarca.

Update 17/02/2017: added 1200dpi scan of the original plan page, thanks to RogerC41.

Here as promised on RC Groups is a 1200 dpi scan of the Brooks Biplane from Aeromodeller November 1952 [see supplementary file 'original_page_scan_1200dpi']. This is really just for completeness.

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.
