My P3P has a drift issue when hovering close to the ground!
I got a new downward sensor for $3 and change from a seller with good reviews! I also ordered the landing gear and new antennas and a screw set to replace all of the old ones with new! If after I replace all this stuff and it still drifts could it be the motors? I hope it’s not in the main board
It sounds like you have no idea what the issue is and you're just replacing parts at random.
It would make much more sense to identify the issue and deal with that.
Most of the things you've mentioned would not be involved at all.
It's not possible to work out much from your description.
You haven't described the problem in any detail, but something caught my attention.
You said that it happens close to the ground.
Are you aware of the limitations of the VPS system?
It only works where the ground has a definite texture or pattern and the lighting is good.
If the surface is plain like grass or concrete etc, there is nothing for the VPS to lock on to and it's going to wander trying to find something to lock onto.
It's easy to check to see whether this is your problem.
What surface are you hovering over? At what height?
If you climb past 10 metres does that fix things?
If you disable the VPS does that make a difference?
If that doesn't sort things out, a look at the recorded flight data might help.
