Hello,
can it be done?
can i connect a phantom 3 or phantom 4 to the air unit of the lightbridge?
i have a remote from a crashed phantom and i want to buy lightbridge 1 or 2
can i buy jest the air unit?

Thank you all!!

No you cannot use either a P3 Pro/Adv or P4 RC to a standalone Lightbridge unit. Lightbridge 1 can only use 3rd party RCs or older DJI RCs (P2 or DR16) that have training ports in the back. Lightbridge 2's ground end is built into its RC and can only be paired to other standalone LB2 units or the M600 series.
