When it comes to lightweight 3D foamies, micro helis and indoor slow flyers, every ounce you can eliminate means better performance and longer flight times. Weighing in at a scant 2 grams, the Spektrum™ AR6310 model is the perfect receiver for these types of applications. Not simply because it's so small, but because it gives you the superior response and interference protection with Spektrum DSMX® technology. Its JST connectors are compatible with the Spektrum programmable DSP60J Digital Super Sub-Micro Servo (SPMDSP60J), the 2.5-gram A2010 Ultra Micro Servo and the 4.3-gram A2020 Nanolite Servo.
