might be a noob question but when landing my p3p manually it will sometimes suddenly gain height when im about 1ft from the ground, almost as if it is fighting me to land. im in p mode.
Yes - the air pressure increases dramatically as you come close to the surface because the props are blowing air down onto the ground and it's hitting the ground and coming back up. So the increased air pressure makes the craft "think" it has suddenly dropped too much and compensates.
Could also be your stick handling. There is quite a bit of prop wash downward. Try being a little more deliberate with left stick down. Hold left stick straight down for 3 seconds to stop the motors once you have landed.
Without seeing this it's hard to really evaluate.
I don't give much creedance to any of the barometer based guesses. In an otherwise normally functioning aircraft when you command the craft down it should continue to do so despite the Barometer.
My first thought is Ground Effect. Simply put... additional lift created by proximity to the ground.
It may also be your technique. Again without witnessing it it's hard to evaluate with certainty.
Yes, I have experienced this with my P3P several times. Mostly it happened when approaching the ground very slowly hovering to focus in on the exact landing spot, then just as I pull back to land, it quickly "hops" up maybe a foot or so prior to comply with my pulling back the throttle.
I thought it might have to do with the VPS, but the barometer theory sounds more plausible.
Usually I hand catch it but whenever I land on ground, I use a flat board and never noticed upward sudden movement. There is definitely some ground effect but notice alarming.
