DJI O4 Air Unit Reviews

Both had No SBUS

By Dan
Rated 3 out of 5

I bought 2 of them and my Friend also bought 2 and they all worked quite fine as a VTX but none of the 4 had working SBUS receivers in them.

Great product. Fast shipping.

Excellent place to source O4 air units. Fair pricing and very quick shipping. Will definitely come back to B&H with the purchase/building of each new quad.
