If you arent dead set on the parts you have already choosen you may want to consider something like this. http://www.amazon.com/gp/product/B00YACIDNU?keywords=emax%20250&qid=1451850415&ref_=sr_1_1&sr=8-1 I bought one of these when I build my first quad recently and was quite pleased with it.
This kit does not include standoffs for mounting PDB and FC though, i just picked some up from ACE hardware.
Perfect!!! I decided to use that!
Can you let me know if you see any problems with this list?? Anything I can improve?? Anything I don't need??
Drone Battery 1 (heavy) 2200mAh
Drone Battery 2 (light) 1800mAh
What's the cheapest way to be able to get voltage to show on my FPV setup?
-Would I be able to use this voltage checker/warning buzzer?
What about a cheap lost model buzzer/discovery buzzer?? Can I use a switch on my Tx to make the alarm sound??
Is it overkill to get 3 batteries total?? 2 for the drone (So I can keep flying when one is charging) and 1 for the FPV reciever/display?
Thanks for the help!!
