having escs mounted on the bottom isnt a huge problem, but it definitely isnt optimal.
looking at the build as a whole just..what the FUCK... at first i thought i was looking at the middle of the quad, like you removed the top plate/standoffs to look inside...but just...what the fuck. is that the PDB just chillin fully exposed? thats a short waiting to happen. everything is just...exposed. this has to be some kind of mistake, link to the product page?
EDIT: is it this one? its clear in one of the pictures that its being sold this way...but why...just why. cant believe people buy this
