04907 VControl Battery ID Sensor

This item is a pretty cool thing to have on your Heli if you are a logging statistics nerd. That is if you can get it to work reliably. The tolerance for tag proximity to the reader antenna is rediculasly small and requires a great deal of tweaking to get the tags positioned properly so that you can use your batteries with more than one Heli. The adhesive on the tags is worthless. You MUST find a different method to attach the tags. And of course you are tweaking location while you are trying to get the tag to stick. I have three of these readers and I am constantly twiddling with them to make them work.

This was the first time trying the battery ID system. Figured I only have two packs per 700heli so why do I need a battery ID system. Well I got to say, it's pretty nice not having to remember which pack I put into the heli. In conjunction with voltage UI sensor, I can plug in and fly with no worries every time!
