This is 2nd upgrade on my eRC quad. It's very simple and straightforward.
The hole point of the voltage display on a quad is that you can see battery voltage before take off and even in flight by doing a simple flyby. This is completely optional, but I think it looks cool and it really helps a lot. And for extra 4g it's awesome.
I've installed it by simply jamming it between lower and upper plate. It's perfect fit and it doesn't go anywhere. Of course, you can put it wherever you want.
WARNING:
1. Be very careful when soldering wires to the voltage display. You shouldn't switch positive and negative wires. If you did everything as I said in "KK2.0 voltage alarm" video, then just make sure you solder positive to number "2" on JST connector and negative to number "1".
Tips:
1. Good idea is to set the reading slightly under actual voltage because it's better to think you have less juice than more.
2. Measuring battery voltage without load (like I did) isn't quite right because you're comparing that with voltage readout from battery under load. However, load is really small and it's not easy to measure voltage once you connect your battery to the quad. Also, this voltage display is not that precise so this doesn't play a big role here.
You need:
Phillips screwdriver
Any 30W (or similar) soldering iron.
Enjoy RC as much as I do! :)
I'm modifying a little one of my SK450 to add my FPV gear on it I hope I can add some pics soon. if I'm lucky that it fly well with the FPV I try with the dead cat conversion but did not like how it flew so I change back to the original and add some modes. I was thinking that you might have try something new lol so hope to hear/read from you soon!
Fly Safe!
