Ace Foam Wing (oz8557)
About this Plan
Ace Foam Wing. NACA 2415 Taper Wing. A balsa alternative to the classic Ace Foam Wing.
This is a modern redrawn plan in vectorPDF format.
Plan shows built-up balsa construction replacement wing for the discontinued Ace Foam Wing used in many 1970s RC designs [see /search/results.asp?keyword=ace+foam+wing&searchcompletetext=Yes for examples].
Note this plan shows a tapered wing, but a constant chord wing can also be built from this, using the root rib template. Wingspan is 35in discounting the shaped wingtips.

Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

User commentsGreetings, I was contemplating the designs that use this wing design when a thought occurred to me. Has anyone ever weighed an Ace foam panel, and compared it to the weight of a panel built to this plan? I assume the wood panel would be lighter, but it would be interesting to know the real values.

* 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.
