Warning Picture heavy Long post
So after owning a modified RMRC tracker with EagleEyes Diversity tracker unit i wanted to step up a gear and build something a bit tidier but also that enabled me to switch between 1.2, 2.4 & 5.8Ghz.
I would use NexWave Fatshark Modules mounted on Vero board so that they can be swapped out in seconds,.
I decided on one of Rory Games EFPV trackers with the upgrade kit.
Below are some starter pictures for sizing and also some of the build stages. As always click the pic’s for the full size versions
This is a top down view of the tracker , notice the holes into which the VRX modules will sit nicely.
Here we have the top section in progress, you can clearly see the slip ring section with the 12 wires for servos and the VRX modules, wiring was certainly a challenge but not impossible.
A very nice smooth ball raced section with pinion gear which i lubed with a small amount of grease.
The underside of the slip ring and the pan servo in shot now.
Top section completed apart from the wiring ,now for the fun part getting all the ancillaries into the bottom box.
Started wiring both top and bottom sections now. Will move onto the modules.
And here trying to keep the wiring tidy
The VRX’s were to be mounted onto VERO board with 4 way DIL switches and PCB edge connectors for easy removal.
Here’s some shots showing real world dimensions for those interested.
Now i had to transpose the pin outs of the VRX onto the Vero board which was reasonably easy, however some kind soul had already done a Vero board layout.
Below you can clearly see the tracks cut underneath the 4 way DIL switch.
Switch 1 on the DIL switch is UNUSED.
It IS worth noting that the pin outs on the 2.4Ghz VRX modules are different please see below.
And a 2.4Ghz (Left) & 5.8Ghz (Right)unit side by side , notice the audio channels and switch pins are swapped.
Here we have three VRX modules made up almost ready for use.
Now some almost finished pictures, i need to tidy up the lipo feed wires and generally tidy things up but you can see the progress.
I’ve also included some pictures of my old tracker for comparison.
Feel free to ask questions,and ill try and answer the best i can.
