Looks like diatone have made some more improvements to their SP series of video transmitters, now the SP3 has a built in OSD, and 48CH. The other useful feature is that it also has the ability to switch power levels between 0mW, 25mW, 200mW, and 600mW, so if you are doing some FPV flying with friends you can set it to 0 when you turn on your quad to stop you jamming their signals! This is the new video transmitter used on the crusader GT2 kits.
