KDE have released thier new tail pitch design upgrade for the 500 series.
“The ALIGN TREX 500 Series continue to be one of the most popular class of RC Helicopters available on the market and has been reborn with the launch of the newer TREX 500 PRO edition. To further improve the flight characteristics and tail authority, we are proud to release the KDE Direct TREX 500 Series Performance Tail Control. Based on the proven design features of the Performance Tail Control for the 550/600 and 700 Series helicopters, the upgrade provides a continuously smooth, failure-free operation even under the hardest and most extreme flying conditions. You can see the CAD design in action (rendering animation) on YouTube to see the full advantages.”
