I remember learning abt TX and RX frequency being a fixed number of MHz away from each other, too bad I forgot wads the value. Yeah but basically TX and RX have a certain paired frequency and the frequency listed on both side of teh set usually only show the RX freq.
More and more I believe that the Crystals in the picture should work. I downloaded the VS tank manual and it shows a table where it says that the transmitter frequency is 27.045 MHZ and that the receiver frequency is 26.590MHZ. There are 6 different frequencies and always the transmitter is .455 MHZ 'higer' than the receiver. In every store that I have enteres looking for VSTanks, they generally only show the transmitter frequency.
So I don't know about HL, but this crystals will probably work on VS Tanks
