About this Plan

UMX Tristar EDF. Radio control sport model, with electric ducted fan. Wingspan 17-1/4in, wing area 47 sq in. For EFLDF180M2 fan unit.

Quote: "UMX Sig Tri-Star 180 EDF.

This is a scaled down version of Sig's .15 size 2-stroke model by Leroy Satterlee which I have as electric conversion. I like the full size version so much that a few years ago I built my first micro version of it powered with a Parkzone UMX F-27 Stryker system. It was a quick build and as such, not the strongest plane. So for my new one, I decided to learn how to use CAD and draw out my first plane and solicit my dad and his laser to cut it out.

A few changes that I made were power source (obviously) and a single central mounted vertical stabilizer with a rudder rather than two wing tip mounted vertical stabilizers with no rudder. The reason I did these is because I thought it would make for a cool EDF and because on the full size model the lack of rudder can make interesting last second corrections on landings. I am also using this plane as a test platform in case I want to super size it in the future. It will be powered by a single E-Flight 28mm fan unit on 2S."

Notes

* 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.

Scaling

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.
