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

Hi just thought I would let you know after downloading this plan and starting to cut out the parts I think I have found a few mistakes on it, so far they seem to be limited to the wings the rib patterns aren't the same and the wing construction aren't correct if measured there are quite a few discrepencies that make construction most difficult to the untrained eye I hope me pointing this out to you will help others who want to build this aircraft

Very nice looking airplane with style & simplicity. Thankful that is does NOT have a RINGMASTER wing. The rectangular wing is very good, a lot simpler to cutout & build time is reduced. When cutting ribs it makes it easier to cut enough for 2-3 wings.

1 more comment about the wing. Cut wing rib sets are offered from BRODAK. They have a lot of rib sets to choose from & price is reasonable.

Wing rib template lead-out holes are pitched incorrectly to suit 3" bellcrank lead-outs shown on plan. Cheers,

* 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.
