This is my first micro build, but I really like it so much.
It was coming in a DIY set from helipal, and in this set there was almost everything there what I needed for the build. I am really happy with the supplied parts, the quality is great, there are only 3 parts what I found not OK in the DIY kit:

  • for the battery cable is better to use AWG16 cable with XT30 connector
  • better to change the VTX for a stronger one, I think I will go with TBS Unify
  • The original battery straps are useless, they are too short for any kind battery

BTW: I broke my camera lens fixing ring, and can’t buy it anywhere for the RunCam Micro

Update: After a small crash ( its crazy because not even the prop was bent and the motor has not had contact with anything) one of the magnets moved out on the motor :( No chance to repair, have tu buy new motors.

Update: I added the FrSky r-xsr and the TBS Unify 5V, so I have now telemetry and also smart audio :)

Thank you! Unfortunately the motors are not very durable :(

You can buy those camera rings. I have purchased them before in a pack and they are better than the stock ones. LMK if you need a link.

Napalm   Sep 10, 2017 

Please send me the link. I can not find them because they are not M12 like usual camera rings, they are M8.

Great!.... Are you sure 4s 650 on this little thing??? Not to heavy????

Napalm   Sep 08, 2017 

Sorry it was my fault, i run it on 3S, but you are right, the AceHe LiPo's are to heavy, so I am waiting now on some lighter LiPo's.

My first choice was Gensace, but they are useless.

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..
