title: RC Equipment description: My gear and the modifications I did to it parent: quadcopters position: 80 date: 2015-10-09 update: 2021-05-28 --- Over the years of flying quadcopters and other stuff I have grown quite the collection of self-made or customized gear. ## Spectator Monitor When out flying alone or with a partner, often people walk their dogs nearby or families go on a walk together and see us. This often sparks a conversation. For these occasions, it turned out to be very useful to have some kind of second screen and receiver with me. A friend of mine even has a spare cheap set of FPV goggles with him most of the time. I decided to go a slightly different route. For my first experiments, I bought the [Quanum DIY FPV Goggle Set](https://hobbyking.com/de_de/quanum-diy-fpv-goggle-set-with-monitor-kit.html). I didn't really like the box-style of goggles, so I quickly took the monitor from the set and used it stand-alone. After I switched to proper FatShark goggles, I used the Quanum monitor again, this time for a spectator monitor. I built a simple wooden box out of left-over parts and hot-glue, with a large cut-out in the front for the monitor. Inside is not only a [FR632 Diversity Rx](https://hobbyking.com/en_us/fr632-diversity-5-8ghz-48ch-auto-scan-lcd-a-v-fpv-receiver.html) but also an [Eachine ProDVR](https://www.banggood.com/Eachine-ProDVR-Pro-DVR-Video-Audio-Mini-Recorder-for-FPV-Multicopters-for-RC-Drone-FPV-Racing-p-1061196.html?cur_warehouse=CN), 2x 18650 cells, voltage regulators, a fan and a voltmeter. The channel can be selected on the receiver, with cut-outs on the back. The DVR can be controlled using external push buttons. A power switch, as well as a switch to select either the Rx video feed or the DVR video feed, are on the top. The batteries hold up for maybe 3 sessions with spectators. I had to add the fan after the first tests because it simply got too hot inside the box and the first DVR died after a while. The quality of the Quanum monitor is great and it does not switch to a blue-screen when the signal is fading. The DVR does not work 100% reliable, but considering my FatShark Dominator v3 has a built-in DVR as well, I'm not really dependant on it. ## Customized Transmitter Also see [the article about my Arduino FrSky Telemetry display](2016_11_05_frsky_telemetry.html) and [the article about my Saitek X52 USB joystick experiments](2016_07_24_usb_host_cppm.html). ## FPV Monitor ## Spectator Monitor 2 The files for the modified 3D printed case [can be found on my Thingiverse profile](https://www.thingiverse.com/thing:2003324).
