JR bay fan mod for Express LRS with beefed up clips and extra cooling holes

thingiverse

I have drilled cooling holes in the module bay of my old Turnigy 9xr Pro Tx and I wanted corresponding holes in the bottom of the module case (I have soldered a heatsink cut from copper sheet onto the bottom of the RM9 tx board where the grid of vias under the power amp chip are, after carefully scraping off the solder mask with a scalpel). I also found the clips were a bit loose which meant the module could move around and even intermittently lose power, so I made the groove in the clips narrower. I also managed to break one of the clips so I added extra thickness at the base of the clips.
