Hi Vin, FPV is not a Kit or something you can buy, but you need to find and connect the right components based on your needs ans your existing Hardware.
You own a Spectrum, i assume 2,4 ghz, so your future FPV- Equipment has to work with 5,8 GHZ. There are several shops and offers for FPV Equip, i has good Experience with 5,8 stuff from Immersion RC in combination with Cinemizer Goggles and/or Fat Sharks.
Mounting on the Copter is also important, take care to not create groundloops and interferences between VTX and RC-TX. This
