It's a 2.4GHz VTX, so you'll not be able to use a 2.4GHz radi= o set with it.

I've been making small FPV modules lately, I use the RangeVideo 200mW 5.8GZ modules and then one of the microcams from FPVHobby. =A0The RV
modules are cheap - $20, but use the 'A' set of 5.8GHz channels for=
which you'll need a matching RX, RV also sell them. =A0They aren't<= br> compatible with the common RC305 receiver that HobbyKing and others
sell. =A0Also they are strictly 3.3V, so I use a diode in series with a
1S lipo to power it which seems to work fine.

FPVHobby also have 5.8GHz modules, they can take 5V so straight 1S
lipo is fine, so a lot more convenient, and they are compatible with a
standard RC305 receiver. =A0They are $40 though, so you have to make a
choice there.
