Very easy to set up. Works as described.cheap and easy to install, does leave a see through dark patch where read out is, mine is stalk set up but I think the numbers would be hard to read without it, I never callibrated instead I flew and checked batter on ground then Just new 11.3 v was time for me to land.This thing is great! I wired it in line with an immersion rc 600mw transmitter and HS1177 camera, I took the power for it from the line coming out of the fat shark power filter, which feeds from the batteries balance lead. I only have one power line going into it as all I really care about is my flight time and remaining battery level being available on the screen.
Easy to install, it doesn't take long at all, I looked at what others had done on site and checked their wiring diagrams to see what they had done.
Straight out of the box it provided an accurate read out of the power remaining in the battery, this was checked against a battery tester and found to be correct.
The OSD menu is easy to use, you just hold your finger down on the button and once the menu is up you can cycle through the different options on the screen to place the numbers where you want them, Once you have selected the one you like it stays stored in the unit.
For any rc vehicle where you need to know your battery levels or flight time, this thing is great. Don't be fooled into thinking this is too hard to set up, with a little research on this site you will be off and flying in no time. I have mine on a 250 sized quad.voltage seems a little bit off, but i guess it's fine.Excellent value. I have this setup on my base-station side of my FPV gear, so I can see how my receiver-side battery voltage is doing visually!Just works and easy to fit to my 250 Quad.Item arrived one week from international to CA usa. Easy to setup. Just run parallel to ur video and if using one battery to monitor hook up to batt2 input plugs. Easy and works well. All i need for my fpv quad. Good buy!work great with crius aiop and little mod for rssiEnded up not being able to use this since I've ended up going 4 cell. Will replace with a minimOSD which is better and cheaper.Great, cheap and easy to install
