Note this is a plan showing how to make a wing only. See instructions on plan re purchase of fuselage components to match (model 132 fuse and tail set from

Quote: "Hello, I have been downloading from your site for years and feel that it's time to start to repay for that privilege. I designed a 3.8m electric sailplane a couple of years ago and had the help of a wonderful CAD man I met on RCGroups. It uses off-the-shelf fuselage components and only the wing has to be built... Thank you for starting and maintaining such a wonderful web site. Mike,"

Update 23/12/2017: Replaced this plan with a revised version, this now includes sheet #3 showing all wing ribs, thanks to MikeMcCrabb.


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

The trailing edge is unclear, quite how it fits. Do the ribs have capping strips or should the CF trailing edge be inset somehow?

I believe the the TE is inset into the ribs and the gussets used to reinforce the joint. Though it is probably easier to cut the last 5mm off the ribs than to try and slot them.
Personally I would also cap the ribs with thin carbon that extends over the TE.

* 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.
