About this Plan

Frog Jupiter - Free flight rubber sports model. The Jupiter was kitted by Frog between 1947-1950.

Quote: "FROG Jupiter, a 36in span low wing semi scale model of a sports aircraft with snappy flying qualities". This plan shows all fuselage formers, but only the root rib - no patterns for the other ribs.

Direct submission to Outerzone.

Update 12/10/2016: Added new wing layout drawing, thanks to RonaldL. Quote: "Finally found the time to resize the wing layout. It's not the most precise or advanced drawing but should be sufficient to build a wing from. At least it was for me. I would be most delighted to see someone else taking advantage of it. Ronald"

Supplementary files

Wing layout drawing, includes all ribs.

This is one of my all-time favourites. Thanks again to Mike Stuart who runs the excellent www.houseoffrog.co.uk site for submitting this one. I like the styling of this so much I have ended up using the artwork as a site logo for Outerzone. I must get around to building this one day. Will probably end up with 3 channel RC and electric power, as a park flier, so with no undercarriage.

Hi Steve, I posted the wing layout for the Jupiter in my build thread at http://www.rcgroups.com/forums/showthread.php?t=2639421 I'm happy to be able to contribute to your great web site. Please also use a picture of my Jupiter to add, as well. My Jupiter has an enlarged wing +20% span and chord and flies nicely at around 230g. Best regards,

I've added a few of your fantastic photos, Ronald, I hope that's OK [more pics 003-006]. The Lego jig is genius!

* 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.
