hey, I’ve recently brought a P3S to get in to drone flying and videoing. I brought it off eBay for a good price as it had some upgrades. Seller was honest and very helpful answering questions afterward. So it works fine no major problems. First couple of flight I just flew it up out my garden, I kept getting a warning about strong interface. I guess from the house? So today I took it down the park right by the harbour. Big open area and I still got the same warning. It’s has an uprated antenna. I flew it out about .4 of a mile and then the auto return to Home kicked in. Is this about normal as I was expecting at least to get a mile. Am I positioning the antenna wrong?? Or is that really the max range??
