A lot has happened since I started this build. You can see in the image gallery different variations of this MRM Micro Scythe 130mm frame. I will go over the different versions starting with the oldest pictures at the bottom of the image gallery.

Version 1
The first problem was the used electronics I purchased RCG (RC Groups), one of the ESC was bad. Then I tried using the Micro 600TVL Wide Angle FPV Camera w/ Mic CC1563 that this frame was designed to use but I did not like how a large portion of the camera view was blocked by the props. To make matters worse, I was using black props too. So, I think clear props might of helped. This should be the lightest version because of the smaller camera and mount. At the time I only had a 600mw cricket VTX but that was only temporary.

Version 2
To solve my problem with the prop in view of my FPV camera I went with a POD style mount and Runcam 2. The quickest and cheapest thing to do is 3D print a pod. I did a quick search on thingiverse and found a perfect setup. This new setup added a little more weight but it still flew great. Without the battery it weighs in at 187g.

Version 3
Like always, I like to upgrade things and that is exactly what I did. Other than the FC I switch everything out. New motors, Camera, VTX, Antennam PDB, 4 in 1 ESC and camera Pod. With this new setup it weighs 174g. The newer and lighter pod was taken from a QAV ULX clone. Its basically 4 standoff and a carbon fiber plate on top. If you want the side carbon fiber plates you just use some zip ties to secure it.

So the FPV pod you made. Hows it holding up and what material was it printed in?

Sorry for the last response, I did not see this message until now. I printed it with PLA. Here is a link for more detail on the print: http://www.thingiverse.com/make:292781
This pod is like a TANK! Even after dremeling out some material around the pod and it is still rock solid. I have been a few crashes and it is still holding up strong! Please note, I did not design this pod, I just download the files from thingivese. http://www.thingiverse.com/thing:1618876

In late 2019 DJI made inroads into the FPV scene with their remarkable low-latency digital system. It gave us a 720p video feed with latency on-par with the status quo, analog video. Traditionally we've used analog video systems for low-latency video, but the video quality is far from ideal. It's a trade-off we've been willing to accept for the control. Now we've got the best of both worlds and what..

When the FatShark HDOs hit the market in 2018 the FPV community rejoiced for the new Sony OLED displays. While they lacked further upgrades like an updated DVR and power button they were still a market success. With the 2019 announcement of the Orqa FPV.One the community finally had a potential HDO killer on the horizon. With only weeks before the release of the Orqa FPV.One Skyzone came out of left..
