Very little room. Maybe 2.5mm. I've already got them soldered on and it looks ok to me. I guess I could have hid the wires a little better but this build is so small my nerves would need some professional help.
I think I would definitely run those motor wires under the board. Those wires are high frequency and could interfere with the receiver unless you mount it under the top plate. Probably won't cause an issue, but it has my spidey sense tingling.
I'm gonna have to see what happens with it mounted to the bottom plate. Mounting to the top plate is a no-go. The antenna wires would get chopped by the props.
Why not put it under teh center of the top plate? Would be out of the way of everything. Again, It could never cause issues being near those motor wires, but I like to play it safe. Sometimes lol.
Few more photos this morning. I got the receiver, dvr, and battery cable soldered on. I am pleased to find out that the standoffs that came with the camera will be within 1/2mm from touching the top plate. This is good news for the vtx that I'll get tomorrow.
