Aluminium Heat Sink 19x19MM - Black 1PC

It's normal for a 5.8G FPV video transmitter to heat up when powered on, but an over-heating transmitter will result in reduced range and the video quality will drop too. If you can't move the VTX into airflow to cool it down, another option is to add a heat sink to it. We sell these small aluminium heat sinks which can be attached to your transmitter using thermal adhesive tape.
