This is a thing of beauty. Both the finished engine, as well as every single detail drawing, of which there are many. A masterpiece!

Hello, I am new to aero engines I usually build marine steam and of Jan Ridders petrol engines, can you tell me what kind of carb is used on a caster oil methenol engine. Andy.

What a project. It's like building a four engine 747 with four gas turbines, and a Space Shuttle to set on top. Just the CAD drawing itself is a work of art, waaaay beyond my capability. A carburetor was not shown on the drawings, but a possible addition would be to find an existing glow engine of about the same size and steal the carb off of it. I saw one of Forest Edward's engines at one of our club open house events and it ran beautifully, didn't notice the carb mounted on the rear. The popular Walbro carbs used on Weedeater motors are a possibility, but they would have to be modified to run on glow fuel. You need a LOT more fuel for a glow engine and a gas carb would have to be drilled out in the jets to work with alcohol, not an easy task. I would try a carb from an existing glow engine.

Read General Notes, it uses common Perry carb.

Hi, You will need a carburetter from a .40/.60 size glowengine. Run in the first 1 1/2 hour or so with metanol with 20% castoroil, after that mix with 6-8% synthetic oil p.e. Aerosave. Clean it out after the castoroil befor you swiths to synt. oil. Success.

* 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.
