The vertical camera broke off a while ago. I don't want to throw this drone away, because it was great while it worked - but it's really hard to find parts for this thing, outside of an abundance of rotor blades.
You can utilize any FPV camera unit that runs on 3.7v power (I used a GOQOTOMO GT camera/transmitter from a wrecked tiny whoop). Just attach the red power lead to the back port-side power plug and the black lead to the starboard-side rear power plug on the topside of the Mambo. I hotglued the camera unit to a lego brick, which clamps down the leads similar to the cannon attachment. Camera units are under 20 USD on Amazon. Power draw does not affect drone performance and reduces flight time by two minutes at most, VTX range exceeds the range of the flypad.
