DJI Phantom 3/ Inspire 1 Controller / Video Split Range Booster ~ Windsurfer style 2 Antenna mount(2 part system). This simple reflector will significantly increase your controllers range without any modifications to your controller. It works by focusing the signal that would normally be transmitted 360 degrees & lost behind you, back in the direction of your phantom, Strengthening the signal sent & therfore increasing your range. Research it on bing. Easy on/off instillation on the controller. Watch the video to see all info and the other styles of windsurfers I offer. This one will allow you to do the V shape with the boosters as some like to do.

Results were pretty good: Stock: 16040′ – lost control: RTH With my booster: 16936′ – lost control: RTH With David’s booster: 18857′ without losing control. 5 bars on video, 1 bar on control I didn’t push it as I wanted to make sure I had enough battery but it was no problem. I flew ATTI only for a short section on the return and landed with 26%. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Do to high demand there is currently a ~ 5 TO 10 day lead time ~ I print all my items to order. When your item is done printing I check the item for defects. Then I prep the item (Sand, File & or Assembly). Then I VAPOR SEAL the item. This is done with a Chemical bath. By Vapor Sealing the item the result is a STRONGER item & it gives it a more “Injected mold” Look by smoothing the Appearance of lines left by the printing process. (This is more visually noticeable in Abs then Pla) I make every item like its going on my Quadcopter so you can be sure you will a Quality part. I have 100% Feedback because I WORK with my customers. If you have an issue with any of the items or want to see if I can customize it for you.. just send me a message. I’m very easy to work with. All items are Available in many different colors & I’m continually adding more.
