Made 1mile (1.6km) FPV today w/ Phantom 1 :)

First milestone crossed off the list. Going to make a few changes and shoot for 2 miles next. :mrgreen:

Wow! A fun ride, but the video quality is terrible. What kind of camera are you using?

Good flight though.

How was the FPV video feed that far out? Seems like that's pushing it for a 250mw TX... I could be wrong though!

A small bit of break up about 1/2 way there, repositioning my head up fixed that issue. At 1 mile it was good, until I turned around - then complete video loss.

Having the vtx antenna pointed out back isn't a good idea once turned around, so I'll be repositioning it to the side for the next flight. Also going to add a 5 turn IBCrazy helical directional antenna on the goggles too. Most of the video reliability is on the receiver antennas side - 250mW should be enough for 3-4miles+ with a good receiver antenna. Also, keep in mind that the FS 250mW often tests higher than advertised, while the IRC 600mW tests lower. I've actually seen some tests showing that the FS 250 puts out more power than the IRC 600 - who knows.

Here is a neat video comparing a Helical to a Crosshair antenna using 5.8ghz. Notice the distance - 10km (6 miles)!
