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:
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.

Until recently GoPros were delegated to larger quads. A typical GoPro weighs around 125g and we've only recently begun to mount them on 3" cinewhoops. Even that is a stress on the motors. Now we've got the "GoPro Lite". Remove the battery, displays and casing and you're left with a small, lightweight board and sensor. Wrap it in protective TPU casing and you've got a 30g micro GoPro. The Hero6 is..

This guide will walk you through the process of building your first FPV quad. The goal with this design was to build a low-cost, lightweight quad, yet powerful enough to safely carry a GoPro in close proximity areas. I chose these parts to minimize the amount of soldering at no cost to the quality. A typical build requires around 30 solders while this only needs 25. It's not a huge difference, but..
