About this Plan

Thunderstormer - Radio control pattern plane, for Veco .61 power.

Quote: "The whole thing started out as sort of a joke. Don Mathes and I decided to see how small a fuselage we could wrap around the Micro-Avionics receiver and servos. Would you believe his is skinnier...

*N.B. Please note this plan takes longer than usual to open. It will get there eventually, but you may need to be a little patient ... :)

User comments

I've lusted after this design since I first saw it published in RCM. As a member of the USAF with but two stripes on my arm, there was no way I could afford the required radio equipment. The Digicon radio set it used sold for about $1000 in 1966 non-inflated dollars. Doug Spreng and his buddy Don Mathes were the creators of that system, the first in the world that used their revolutionary servo design, instantly copied by all the other radio makers. Problems doomed the Digicon to a short commercial life but others used the servo circuit with success. The exact same system is used today in the vast majority of current servos.

* 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.
