New Yard Ace Page

I added a page on my build of a park flyer sized version of my Yard Ace design. Very pleased with the outcome, see details here.

The Yard Ace is an easy to build RC model plane that makes for a perfect first build from a set of plans. In this case I demonstrated just how easy it can be to make a smaller version of a model from a set of plans. Same goes for making a larger version, should you wish.

The neat thing about being able to “design as you build” smaller or larger variants of a model from a set of plans is the large universe of new radio control model designs that become available to you.

In a future project I will do just this. First, select a plan of a model designed and built many years ago. Then rebuilt with today’s electric power systems and control electronics. And finally take this “new” model for a flight!

I enjoy Almost and Ready to Fly model aircraft as much as my fellow modelers. Still, it is nice to be able to build something on your own, and have a distinctive aircraft at your club flight line. More to follow!

Park Flyer Yard Ace Test Flight

I had a very successful test flight of my smaller version of the Yard Ace last night!

The total weight of the airplane came in at 2.3 ounces, well below my maximum target weight of three ounces (upper weight limit for the Parkzone motor). I had to add a bit of weight to the nose to provide the proper center of gravity balance.

The plane had plenty of power and flew right out of my hand. Control throw was good, although I think I’ll add either a bit more rudder area or throw to the final version. Handling in the air was smooth ad positive just like the larger version. There was no problem keeping the plane within the confines of my smaller test flight area.

Next steps are to draw up a set of CAD plans for this smaller variant with correct wood sizes as well as modified fuselage and wing layout. As you recall, I used the regular plan to construct this version and adapted structure as needed for the smaller prototype. For example, I’ll lengthen the nose a bit to help reduce the need for nose weight to keep the model within center of gravity limits.

I’ll include this new plan with the regular Yard Ace plan. I also intend to offer a video showing step-by-step how to draw the Yard Ace plan, now that my new Mac offers the capability of screen recording.
