DJI 5.8Ghz radio with LB question

shaunmed · May 16, 2014

I have a P2 H3-2D. I recently got LB. I have a spare P2 Vision radio. Can I use that radio with my set up?

In other words, how does my P2 communicate with a 5.8Ghz radio when its original radio was 2.4Ghz?

Yes you need to swap your receiver with one of these 5.8GHZ receivers though

oh the hell with it. i guess i'm just gonna buy a futaba. doesnt make sense to waste money working around something that would work better if i used a futaba and the LB as the radio.

I think that's the right way to go. It keeps the weight down - with all the non-essential stuff stripped out (2.4 GHz stock receiver board, cables, CanBus etc.) the P2 is still up at 1350 g with the LB air unit and the H3-3D. Also I suspect that the LB radio link is rather less prone to interference.

You still need to operate the gimbal control via separate controller though, is that correct?

Not with the P2. It's no different to using the radio directly - it just passes the control signal via the LB.

Is that from first hand experience? I read on another board there was no channel on LB for gimbal control and it required a separate controller to control the gimbal via classic P2 Rx.

Yes. I have a P2 with Lightbridge - it works exactly the same as running the controller directly to the P2 RX. You may have been reading about problems using LB to control gimbals on other platforms with full 3-axis control, or with dual operator setups. It doesn't apply to the P2.
