yeah, they are, vtx is 5.8ghz, and rx (transmitter one) is 2.4ghz. but the question remains. do you just wire it (rx) to rx wire you have in 5:34 of the first video?
antenna, vtx, and camera are really light (i'm using those on racing quads so they have to be light). would be great to drive with bb8 around the field inbetween batteries on quad and my rc buddies would just love it.
