Description

PDF

I designed this vtx cooler after having experienced vtx getting too hot while waiting for GPS-lock and doing pre-flight checks.

It uses two 14x14 heatsinks usually sold for Raspberry Pi. Just push in place should be sufficient. It also has holes for filament that goes into the VTX holes on Walksnail VTx but that is likely not needed.

If you like my designs please consider donating a coffee or any amount really, I appreciate the gesture.
