Heinkel He 162 (oz13889)
About this Plan
Heinkel He 162. Radio control sport scale model, for IC ducted fan. Wingspan 1515 mm.
Quote (google-translated from the German): "Heinkel He 162 Volksjäger Salamander, by N Gallena.
While the original 'He 162' is a purely German development, this model is the result of German-American cooperation. For years our association has maintained very friendly relations with the local model flight club of the American soldiers. And so one day the chairman of the 'Kitzinger Aeromasters', Loris J Smith, handed me a box with an impeller engine and asked me to come up with something.
After seven months it was ready, the Heinkel He 162. I drew the plan and Loris did the shell construction. Finish, system installation and the test flights were my job again. The motor (6.5 cc) drives a five-blade impeller with a diameter of 120 mm and runs in a tube with a maximum outside diameter of 134 mm. It is mounted on an aluminum casting that is bolted to the outer tube through the six guide vanes. The rear end is formed by a streamlined cone, which is bolted to the aluminum casting. A spinner, which has a groove for starting with the V-belt, serves as the front end.
The entire engine is mounted on the model with a retaining fork and a strap. According to the operating instructions, the fuel should be supplied via a fuel pump and a tank outside the engine. However, I made a brass hammered, streamlined 125cc tank which I bolted on in place of the rear end cone. For practical testing, I mounted the engine on my old high-wing aircraft. For the start I used the engine mounted in the nose, the impeller engine was throttled.
At safety level I throttled the front engine and gave the impeller full throttle. The model lost some altitude, slowly gained speed and in the end was a lot faster than with the normal drive. My initial skepticism was gone. The model flew excellently despite a take-off weight of 4,100 g and the braking effect of the throttled front engine. From the sound alone, the impeller is a pleasure... "

ScaleType: This (oz13889) is a scale plan. Where possible we link scale plans to Wikipedia, using a text string called ScaleType.
If we got this right, you now have a couple of direct links (above) to 1. see the Wikipedia page, and 2. search Oz for more plans of this type. If we didn't, then see below.
ScaleType is formed from the last part of the Wikipedia page address, which here is https://en.wikipedia.org/wiki/Heinkel_He_162
Wikipedia page addresses may well change over time.
For more obscure types, there currently will be no Wiki page found. We tag these cases as ScaleType = NotFound. These will change over time.

* 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.
