It only takes a moment to unplug it, and put a bit of tape over the plug! :dry: Radio manufacturers used to ask that you returned the set WITH the battery, so they could test it! :huh:

Not being able to afford a new Taranis setup I thought I might upgrade my Futaba 9 to something that will give me some telemetry. Height, speed, battery voltage, variometer. I went to Banggood to find a bewildering array of stuff, what the hell do you need? Can anyone help?

I think the reason for the extra weight in the X8R will be the filters and extra amplifier stages in order to get the selectivity required at that long distance.

Eric - I would agree about the possible risk of a LiPo fire but my old second hand Futaba cost very little (and certainly a great deal less than a Taranis! ;) } and the LiPo was half the price and had a bigger capacity that a NIMh pack. :P :P
