The VA2500 combines an FPV camera and a 25mW, 5.8GHz transmitter into a single unit no bigger than a thimble. Its signal range is ideal for small park flyers or racing quads and it can be powered separately or through the model's receiver. Powering it separately requires a 2S or 3S Li-Po battery. If powering it through the receiver, its integrated power filter will prevent interference from the model's motor and servos. The VA2500 is compatible with all 5.8GHz Fat Shark headsets and can be installed in minutes. If your RC system has a spare channel, you can remotely change the frequency via a dial or switch on your transmitter.
