About this Plan

Fire-Fly. Free flight all-sheet model for Jetex 50 power.

Quote: "Hi Steve - Here is Reid Simpson's Fire-Fly from Flying Models magazine issue 08-68. The plan was scaled to the 1/8 inch sheet cross section shown. No reference to overall size was given in the text." Quote from article intro - "Fun for anyone is the best way to describe the Fire-Fly. This small sport plane was conceived with the idea in mind of having something with which the kids could play, fly and chase while Ole Dad went on about his merry way trimming out his latest contest bomb. As it turned out, Ole Dad is having a lot of fun flying the design along with his kids.
The Fire-Fly, while not claiming to be the greatest flying machine going, will ROG easily, climb up to about 100 feet and although not comparable to a Nordic A/2, it does have a respectable glide. The Jetex 50 (Hellcat) motor rather surprised us with the amount of power available, and thus the Fire-Fly has proven to be a highly consistent sport flier even in the wind. The Hellcat 50 motor is easy to maintain, load and ignite, even for younger fliers. At this point I would like to insert a pitch for safety. These small Jetex motors are only as safe as they are handled. With proper instructions, 8-12 year olds can clean, load and ignite these small motors safely. (Try igniting with dethermalizer fuse instead of open flame.) So dads, let's make sure they know how and are properly supervised to start with. Now let's get to the building of this little jewel..."

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.
