Mine got mullered by it. 200 to 300m range max when prior i could go 3 miles no problems.
You were flying out 3 miles?
For a start, that's illegal. The limit is direct line of sight, which I can lose on a 20 acre field.
I also SERIOUSLY doubt any standard Phantom 3 would ever go 3 miles miles without the control link breaking. It's 5.8GHz, only 16dBm (40mW). You'd be lucky to get the specified 500m out of that. The US version with the higher power can only do 1Km.
