Yard Ace Electric Model Airplane
An easy to build RC model airplane for larger venues - great for first time builders

The Yard Ace is designed for larger inside flying venues or outdoors as a park flyer under calm wind conditions. The Yard Ace is an easy to build model plane. The detailed CAD plans make the Yard Ace an ideal first plans built project.
The Yard Ace uses common building materials of balsa and plywood with no specialized building techniques required. Construction is simplified with a constant chord wing and an open frame scheme for the fuselage.
Designing the Yard Ace was a lot of fun. There really are no tricks to building the aircraft. The wing easily mounts on the upper struts, and there is plenty of room to mount a wide range of radio control gear and electric motor options.
The picture at left shows the finished components of the Yard Ace. The servos mount to the side and poke out a bit, making connections to the rudder and elevator simple to connect.
All the information needed to build the Yard Ace is contained on the plan, from wood types and sizes to full size patterns.
Three channels provide positive flight control. Rubber bands keeps the wing in place.
The prototype of the Yard Ace was built with a shorter wing span than the version shown on the plans. The prototype flew fine, but was just a little bit too fast for the golf dome indoor flying site I used for the test flights. The longer wingspan allowed for slower flight speeds and more benign handling characteristics.
