Varios (variometers) for RC gliders explained

In this, the last video before my walls went up, I show the new high-precision variometer from FrSky and give an overview/demo of what varios do and how they work.
This vario can also replace the old telemetry hub used by earlier FrSky sensors and produces a far lighter, more elegant way to interface to either the old or newer (X8R receivers.
Note that in order to get the audio output associated with this sensor you will have to be using a Taranis radio or a radio with the FrSky telemetry system and a suitable version of open-source software such as the OpenTX system.
I'll soon be putting this vario in my DLG and doing a flight video to show just how this vario works in actual use.
This unit was purchased from HobbyKing for the normal retail price.
