Finch takes the drone piloting experience to a whole new level.
In oppose to the well-known lack of performance offered by the 5.8 GHz. The 3.3 GHz system beautifully penetrates obstacles like no other 5.8 GHz can, consequently minimizing the undesirable video drops and loss of video to insignificant levels. 
Besides operating on a stronger and reliable band, the Finch has a dual power level available, that can easily be selected by the user prior to the flight.
Technically speaking the 3.3 GHz band, gives the Finch twice the range in comparison to 5.8 GHz transmitters at the same power level.
