About this Plan

Harlequin. Radio control 2M sailplane. Wingspan 78-3/4 in, wing area 620 sq in. For 2 channel radio.

Quote: "The Harlequin is designed by Mr John Lupperger USA and is an easy to build model that looks good and flies really well on the slope or off the high start. The kit includes exact die-cut plywood fuselage sides and bulkheads. Also die-cut balsa wood ribs are included with spruce spars, control horns and bolts."

Direct submission to Outerzone.

Update 15/11/2022: Added hand-traced ribs file, thanks to Paul Ayala.

Quote: "I purchased an unmolested Harlequin kit on Ebay a couple of months back and remembered the plans here on Outerzone did not include the ribs. I am submitting the scans of the tracings of the ribs from my complete kit.

W-1 and W-32 are 1/16" ply while the rest of the ribs are 1/16" balsa. The tracings are a little bigger due to the thickness of my mechanical pencil which is about 1/32".

I am currently turning these scans into vector format and when done I will send over the DXF and SVG files for these ribs, but in the meantime these scans should be enough for someone to work with. Sincerely, Paul Ayala"

Update 30/3/2023: Added instructions, thanks to RichL.

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

* 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.
