Sky Flieger Build Plans and Info

Written by Clark Salisbury...

This airplane project has been one of the most fun that I have ever completed. I was looking through my covering material and discovered that I had a lot of yellow, red, and black. It hit me that those are the colors of the German flag.

This airplane uses the wing from a design I created six years ago called the SkyEye, but I wanted this model to be able to carry at least one pilot and a Barbie-size passenger.

It has a lot of dihedral that makes it easy to control with three channels. Rudder-only turns are beautiful. The wing loading is low and that translates to fast takeoffs from grass, even at half throttle. I also wanted to have plenty of lighting on the airplane for flying at dusk, so I used 22 white LEDs. My plans show you where to install them. Well, letís get into building.

The girls matching clothes next to the model looks just amazing!

The more I see this model, the more I want one!

I need to clear off a space to build!

3s on that motor is just fine for 75-100W/lb, which is all a 3ch trainer needs.

You're talking 350-450W
