About this Plan

Robbe Tonga. Radio control sailplane model. Wingspan 2740 mm.

Quote: "Dear Mary and Steve, please find attached the scanned and cleaned plans for the Robbe Tonga. I checked the dimensions, they're well within tolerance. The Tonga was a 2,75m thermal soarer, rudder/elevator only, with rather elegant and scale-like outlines. I got mine in '73, it's actually on the workbench undergoing a complete restoration (what includes correcting some serious youth sins). Seems it's seen a lot of rather eventful groundings. Pictures will follow once the restoration is done and pictures can be made. Best Regards, Hubert"

Hello Oz, attached are 2 pics of my Robbe Tonga, taken 2 years ago [model photo & more pics 003. I got the plane sometime in the 70s, on these pics it's freshly restored using silk, dope and Piper Yellow rattle cans. The cabin is new as well. The empennage is modified, now being smaller, lighter and symmetrically profiled. B/R,

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.
