QB 40S (oz10768)
About this Plan
QB 40S. Radio control sport pattern model. Wingspan 1500 mm, for .40 power and 3-4 channels.
Quote: "The QB 40 S is a shoulder wing sport model using a .40 size engine and four channel radio (although it can be flown on 3 channels if you want). Like all QB kit series, the balsa wood is mostly hand cut at the factory with the playwood parts being beautifully die-cut. Hardwood motor mount, steerable nose gear and heavy duty aluminium main landing gear are all included. The canopy is vacuum formed, and all necessary hardwood is included. A full size plan, radio installation instructions and an illustrated construction guide will all make this an easy model to build."
Quote: "Pilot QB 40S including construction sheet, patterns and some drawn formers that are missing from the plan sheets."
Update 15/03/2019: Replaced this plan with a much clearer scan, thanks to Balsaworkbench.
Direct submission to Outerzone.
Note this planfile also includes page 3 (from previous scan version, credit ZarZep) showing 3 further fuselage formers, hand traced.
Supplementary file notes

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.
