What is Minla?

Minla is a RC receiver that connects your RC model to internet.

You can now manually control your RC model (rover, drone, boat, etc.) from your Android/Apple smartphone/tablet or PC web browser via internet.
FPV (First Person View) video stream from internal camera, realtime telemetry data delivered from Minla and control signals delivered to Minla over mobile 3G/4G network and internet. No regular radio equipment (2.4GHz, 5.8GHz, etc.) is required to operate rc model. Just 3G/4G mobile network.
