I decided to make the switch to UHF/1.3ghz for longer range and better penetration around hills and trees. This is a shameless copy of the setup of MelSailsNorth runs. Dual 1.3ghz receivers connected to an EagleEyes diversity controller. I also wanted to gain the ability to "roam" with my goggles on and be completely wireless. I'll be using a blown 600mw 5.8ghz video Tx to relay the video output to my goggles. I also have a 10" monitor on a tripod that will connect to another video output. And in the future, I'll be adding a small DVR as well.
I currently use the FrSky system on my Turnigy 9XR, for my quad and a couple other planes. Since I still want the ability to use the FrSky without having to swap out the module for the DragonLink transmitter, I decided to build a relay box. Below is a list of components I used to each relay station:
ImmersionRC 5.8ghz Tx (old blown one from a crash, low output power)
Wiring harness (XT60 -> 4-way splitter)
3S 2800mah battery
Each of the 4 units (Rx(2), Diversity, 5.8ghz Tx) runs on 12v, so I wired up a straight connection to my 3S battery. I may opt for a 12v power filter or a PowerBox distribution unit, but for now everything works great. We'll see how it performs in the field, and make adjustments as needed. I made my own...Continue Reading
I've been looking into aerial mapping, surveying, and vegetation analysis, and the Skyhunter looked like the perfect ship for this application. Add to that the super stable camera footage I've seen, sporty performance, and a cavernous fuselage, and it looks like a great FPV survey platform.
I decided to build this up with a friend after seeing lots of videos, build logs, and even another local FPV'er fly his. I will be loading this up with the new Pixhawk flight controller, with a couple of extras: airspeed sensor and wireless telemetry link. The OSD overlay will be served by the MinimOSD unit, which connects directly to the Pixhawk. Specific details on the build components are listed below:
In the process now of moving to 1.3ghz for video and will be testing out this setup:
Video Rx 1: ReadyMadeRC w/ SAW filter
Video Rx 2: ReadyMade RC (no SAW filter)
Eagle Eyes diversity
Video Tx: 1000mw from RMRC
Tx Antenna: Cloverleaf
Filter: IBCrazy 1.3/2.4 Notch Filter
Rx 1 Antenna: Crosshair
Rx 2 Antenna: SPW
Mapping Camera: Canon SX-260HS w/ GPS
Camera Software: CHDK
Camera Trigger: Sent from Pixhawk based on the Mission Planner Survey Tool
(PWM servo output from Pixhawk will be run through a 3.3v to 5v step up, then wired into the USB connection for the camera)
My first FPV plane was the great Skywalker 1680. It was a great plane which was destroyed after a malfunctioning elevator servo caused a pretty bad crash. I decided to get out of FPV and just fly RC planes for a while.
But a couple months ago I got back into FPV with some Fatshark goggles and 5.8ghz equipment on my Bixler v1.1. It's a great FPV platform, but lacked the space I wanted for adding OSD, stabilization, and larger batteries for more range.
For my latest FPV plane, I've gone with the Skywalker 1900mm, picked up on the RCG classifieds. As with the shorter wingspan version, it's a great plane for FPV. Very stable and tons of room inside for electronics. The larger wings and higher lift design make it an amazing glider and slow flier. With some help of thermals, I've flown for over 70 minutes and still had 10% left on my 5000mah battery!
Here's the build specs, along with some pictures and some videos I've made over the past few weeks.
I picked the Skywalker for my first FPV plane based on it's reported stability, ridiculous payload capacity, and airfoil design to support that payload. I've had a great time learning about FPV, radio frequencies, radiation patterns, electronics, wiring, and all the other fun stuff that goes along with a DIY FPV build. Attached are some links to what I used in my build, pictures of the Skywalker evolution, and flight videos.

Maiden voyage. No FPV gear added yet, just the stock Skywalker.
