FPV #5 - WL V911 micro FPV heli project

Out of curiosity and desire to fly indoor through first person view i've gather some material and built my very own micro FPV machine.  5.8Ghz Nano VTX, 90 degree POV 520TVL nano 1g nano cam with built in mic and an FP micro 100 size heli that run on 1S lipo battery which fly much better than my old crap Align 100s.  Its 50x better.   Stock heli flown at 6 minutes 30 seconds but after putting FPV load its around 4 minutes max due to sensitive weight.  Since both heli and FPV hardware share the same 1 cell lipo battery its kinda a glitchy  but i get random good and bad videos unless i'm putting two battery configuration.  Overall it flew well with short duration but atleast was a successful implementation for my first micro attempt to fly around inside my house.  I think it would awesome platform if i could use this for fly around inside a haunted house without risking self encounter with paranormal stuff.  Fun stuff but i think i need to research more how to extend its runtime.
