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.
