Hi Mary and Steve: First, congratulations on reaching 9K plan references, plus A LOT of books and mags! Yes, I know you have less than 9K plans on your Database these days, but that is really not your fault, is it? ... The other day I was scanning some old slides (yes, again) and I run across a few photos of the wonderful QB 20L [model photo & more pics 003-009]. I must say the QB 20L is a wonderful model, very stable yet responsive. I built one almost 30 years ago, in 1988 to be precise, from the kit. Powered by an OS 25FP it could do all the usual 'club' aerobatics - rolls, loopings and the combinations thereof. The only thing it did less well was the stall turn as, no matter what I tried, it would always 'snake' a little on the downwards leg - maybe it needed less dihedral/more fin and rudder area?? But the things I liked most were the take-offs and landings - with careful use of throttle, one could balance the model on its main wheels, not letting the nose wheel touch the ground for a couple dozen yards. In fact, one of the enclosed photos shows it doing that 'stunt'. I still have that model in my attic, so one day... Well, there you have it - another group of grainy photos from Portugal. All the very best to you both; thank you for your work - and for the joy you give us, true aeromodellers, every single day (yes, I make a point of getting my 'Outerzone/RC Library' daily 'fix'!).

Hi, I just finished this plane and in the kit was a small drawing of all the formers. I saw these were missing on your site. [see supplement file]. I also added two pictures of my QB20L-II, that you are welcome to display on your website [more pics 011, 012]. Happy to give something back.

* 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.
