Per suggestion of a fellow FPVC member phreakin I decided to build a crab. Have only flown a few packs so far and it feels like I'm going ludicrous speed compared to my shrike racer build. This build, like most all other builds (at least the builds that I do...) presented its own unique challenge in mounting/sizing the stack. Apparently there is an additional hardware kit that you can purchase along w/ the crab for a few bucks more, but alas, they were sold out. So, I was able to retrofit a combination of nylon standoffs/nuts with the super squishy 7mm anti-vibration rubber/metal standoffs to get the stack up to the correct height. Would love to be able to modify the camera mount carbon for smaller camera builds like the mini and micro. As you can see in the photos there is a decently sized gap and the entire stack has ample space between the components. However, there is an actual benefit from having extra space in between the stack layers. Cooling. The most often overlooked factor in builds and likely the result of many premature failures.

Looking good! You should be able to use the stock Runcam Swift Mini bracket to mount your camera, I added the hole in the top specifically for that. That'll get rid of the hot glue solution.

Also, if you still need a 30.5mm hardware kit, DM me and I'll send you one directly.

The EV100 Micro AV Recorder is a DVR for the Eachine EV100 headset. Eachine should have built this into the headset, but here we are. It's about the size of a matchbook and works quite well despite a short learning curve. It's powered by the same battery included with the EV100 and uses the white balance lead. Other than that you can use either of the included 2.5mm to 3.5mm cables to plug it into the video input/output port of the EV100. You can either strap it beside the battery in the headstrap or use the included double sided tape to mount it to the top of the goggles. Vs the Eachine ProDVR This is obviously a repurposed Eachine ProDVR, but it does simplify the design. The ProDVR has different pins for each input and output. In fact the entire side of the unit is dedicated to various keep reading..

Currently on sale for $97, EV100 at Banggood The much anticipated Eachine EV100 headset has finally arrived! Opinions have been quite polarized and unless you've never flown FPV before you're likely to find fault in the field of view (FOV). I've tried a number of headsets and have to admit that I've been spoiled by the FatShark HD2 and HD3 goggles. That being said this is nowhere near that price bracket, so I'd like to compare the EV100 to a few headsets around the same price. Keep in mind that these cost $100 when they were released, so the current $159 price is likely to come down. EV100 vs the Competition I've been a long supporter of the Eachine EV800. It's a great headset for the price (~$55). Feature for feature it's the most comparable headset to the EV100. Both include a keep reading..
