The Neo's GPS module is probably of a lower quality or poorly positioned. Flew the Neo a couple days ago using the FPV RC3. Just up and down the driveway, around the immediate yard, and one pop up above the tree line directly over the immediate yard to take a peak. Tree canopy over the driveway is thick enough to shadow it from sunlight. Only made it ~200 meters down to the mailbox before video reception when from fine to yellow to digital camo in a moment. Normally when trees are leaf free I can just make it to the mailbox. Another 50-70 meters. A few curves. So no direct line of sight to the mailbox. Flying in S mode. Knew would lose video signal at a certain distance from launch pad. I crash in M mode when visual cues get sketchy. And once again satellites went Red to none. Red Warning osd banner. No loss of control. Just no GPS positioning. Like flying indoors with adequate ambient light.
Never had a Neo or Avata2 go crazy with zero satellites locked. At times my impatience with the Neo's slow satellite acquisition has me taking off before Neo has had time to set Home position. Usually VLOS platform. So no big deal that Home is not really Home when the Neo finally acquires enough satellites. IIRC, Neo needs double digit satellite acquisition to set Home position.
