So I have a small update for everybody regarding the P4 range or lack of in certain circumstances.. After a huge amount of testing the best I can do is follows 1. Near power lines & other wifi networks in a reasonably built up area - 500 meters to 1.2kms range at 120 meters altitude 2. Country area no power lines, no wifi networks and no trees - 2.2kms range at 100 meters altitude 3. Over water (zero obstructions) - 2.7kms range at 60 meters altitude (I could have gone much further here but the whole water thing turned me off) Tbh I think 5kms was achievable Without breaking my local laws it's impossible to go any higher than 120mts which would increase my range but be pretty dangerous where I live.. So I'm curious why does this drone do so much better over water at such a low height compared to a country field with no obstructions (like in test 2) at a higher height (ps the reason for lifting the height was due to connectivity issues in test 2.
