Hi Steve, A couple of years back - 2010 to be exact ... a challenge was made to our RC Flying Club. The challenge was to build a Vintage Model & make it RC assisted if need be & to prepare for a 'Vintage Fly-in' which was to be held at our club. I decided to build the SIMPLEX as per your plan No.77. Once again I had the original plan in hand and the results are shown in the attached photos [see more pics 004 - 007] Credit: Bernard & Petro Odendaal. My Simplex initially flew with a 1964 PET OS (.099) which I reconditioned and she flew like a dream - the only problem being the absence of a throttle.... I subsequently installed a Brushless EP setup. My Simplex still flies frequently and I want to encourage anyone reading this to build yourself one of these delightful little Vintage Models. Kind regards,

* 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.
