    Do firmware updates always cause problems?

    I always update when I see a new FW update, and no issues ever.

    Visiting San Deigo CA, Scenic spot? Help please

    Check the B4uFly / AirMap.io. A ton of that area has a lot of controlled airspace, so you'd need to call the appropriate towers and airports. Here's a quick look from airmap.io

    Flying around an airport

    Contact DJI directly, or use their android Beta version that has GEO unlocking. Airport areas can be unlocked only those two ways.

    It works, and works well!

    P4 F-Stop 2.8

    It's fixed. If you want an adjustable aperture, you need an Inspire with an X5 camera.

    Afraid of altitude mode

    I had this happen with my P3S, once the compass errors out, it goes into ATTI mode and there is no more RTH. I presume it's to stop a flyaway, so you can take full control and land it immediately. That one was my fault for calibrating compass next to my car.

    A serious competitor for DJI

    The phantom knock off? Only 1 mile of range. Even the video feed looks odd with that MHz spectrum... No thanks.

    Max 'altitude' below take-off?

    I recall hearing about a -200m altitude limit. I haven't had anywhere to test this though. Although the -700ft is more than that, so perhaps there's no limit to negative altitude. Sent from my iPhone using PhantomPilots mobile app

    How is RC range after the latest fw update ?

    Just hit 2,550 meters / 8366 ft today. That's the furthest I have pushed it to date. I did the FW update last night. That was clear LOS, but started in a residential area and flew into open hills. Never lost RC / Video, full bars.

    Auto-Flight-Logic

    From my understanding, their app doesn't use the built in Waypoint modes, because their app ensures the phantom maintains speed even with windspeed. Also the curves for flight paths are more accurate. It'll RTH when you lose signal. I personally like their zip line mode. Sent from my iPhone...

    Will a Phantom 4 avoid hitting a powerline?

    I tested this by not testing a power line, but with a horizontal rope of approximately the same size. It's hit or miss. I had a black climbing rope, and stretched out it recognized it sometimes when moving it closer to the camera. Chain link fences seem to be hit or miss too.

    How exactly does obstacle avoidance work?

    I think he's talking about the downwards facing VPS that works similarly to the OA system. Same concept applies to both. Sent from my iPhone using PhantomPilots mobile app

    How exactly does obstacle avoidance work?

    I found this, basically it's a very in depth subject matter that's still being developed. The word you're looking for is "Stereo Computer Vision" which is able to extract depth information from 2 (or sometimes more) cameras. It compares the same object from two views and calculates the...

    Any SF Bay Area Phantom Pilots?

    East Bay area reporting in! I haven't really flown with any other pilots, well at least since I flew RC helis.

    What range you guys getting if you set the downlink bitrate to 10mbps?

    No, that is right, it automatically will select channel and bitrate on its own according to what's necessary. The farthest I believe I have gone with 10Mbps was only 1000m, and that seemed about right. I started to get choppy video feed, so I turned it down to 4Mbps and went another 1000m...
