It's all basically the same stuff made by Yinhe Technology Development
Co., Ltd. The RF-604 transmitter in your unit is identical to some of
the other 4 channel units sold. The difference here is the flash hot
shoe built into the receiver. Maybe its electronics are subtly
different or your FL-50 has a sufficiently high voltage to allow it to work.
As I said before I know mine work just fine as long as the voltage is
4.25 volts or higher. But somewhere between there and 3.75 is stops
working.
