I have read a lot about the simple windsurfer mod, and since my range was not great I thought ordering one couldn’t hurt.
In the stories I have read, most of the people that have fitted one reached close to a mile/1600 meters, comparing that to my 400m with stock, it should be a great little mod and it costs a few Euro’s/dollars depending where you buy it, but it is worth the money! You can get one here
Standard I could get over 400 meter without any problems or messages.
But with the windsurfer…
(And the magic power mod for video range as described here) I got just shy of 1800 meters
This simple windsurfer nearly quadrupled the range!!
So all in all this is a great addition for the Phantom 3 standard, and when you do the magic power mod too, you will not lose video at that range.
