Description

The new Auri DLG from LD Models is a great improvement over their previous designs, in both quality of construction and contest success. See this RCGroups post from the designer:

Last two years I flew the Stark Pro and found that it was rather hard to fly in dead air. Me myself prefer forward CG and speed flying. So, when thermals are very unstable or when you only have "good" and "bad" air Stark Pro never showed a sign it can climb in something.

My decision was to change the central wing airfoil section to make the model more sensitive to weak thermals. At the same time I wanted to keep penetration and speed of the plane near the same. Also I really like wing's planform of the Stark Pro and didn't want to change it. So, after hours with XFLR and Solid Works new airfoils were ready and we started our work on moulds.

It took 1.5 months to mill wing and tails moulds, sand and polish them. First prototype was ready 1 day before the first contest this season.

I was really surprised when I won that contest with ease. And it was only beginning of my amazing flying season with Auri. Now, when my flying season is over I can say that it is really big success of LD Models team.


The Auri is ideal for customers looking for great flying performance and model toughness at reasonable cost. The fuselage is a one piece design with a generous front to facilitate a four-servos-in-the-pod RC installation, eliminating the need for noseweight. The tailplane (horizontal stabiliser) and fin (vertical stab) are very light and have a good finish. The rudder and elevator are ready hinged, and wing gap tape has been fitted to minimise drag and improve the control response.

The wing is beautifully molded from spread carbon with a Rohacell core to maximise strength and dimensional stability, ensuring the surface finish stays smooth. The design incorporates nicely designed ailerons to give excellent control at all speeds. The hinge gap is sealed with hinge tape, eliminating a common drag source and ensuring high launches.

The supplied accessories include servo mount, tail pylon, aileron pushrods, rudder and elevator pull cables, torque springs, all control horns and a nice asymmetrical throwing blade.
