Dirt Cheap Indoor FPV fun

So wanted to try some indoor fpv as outside there is 6 feet of snow and it lends itself very badly to flying quads outside....
Bought some micro FPV equipment from banggood and also bought a cheap RTF quad and stripped it of unecessary plastic parts.. Glued the camera and VTX on top and had a go..and it worked out pretty good :)
Parts used, NB some soldering skills are needed:
Camera:
VTX:
Antenna:
Drone: UDI 818A, but any suitable RTF drone will work..
