    Battery Storage when not in use.

    Many factors influence LiPo Battery life. Not charging as fully, not discharging as fully will increase the number of cycles significantly, charging and discharging at lower rates and storing at lower temperatures will cause less loss of mAh with time. As a consequence I take mine out of the AC...

    Hey DJI: Easy solution to most crashes

    RTH is a great function so long as it is not activated when you are under an obstruction such as a bridge, power lines or tree branches, or the top of an obstacle between the drone and home is higher than 400 feet above your launch point. However the Breadcrumb solution is much safer under those...

    Just lost pro 3 in the ocean.

    It is not the take off voltage that is critical for a partially discharged battery. The voltage when flying can be much lower when flying, especially on used batteries when they are are not still warm from flying. The internal resistance of LiPos increases at lower temperatures, at lower battery...

    Just lost pro 3 in the ocean.

    I agree that the software should warn about low battery voltage on load. However you also need to monitor the lowest cell voltage while flying. Since I also fly RC planes I often measure the internal resistance of each cell as a warning when batteries have deteriorated significantly due to storage.

    Which Drone; Phantom or....?

    The reviews I read suggested that the range of the Autel was much worse than the Phantom 4, so my reaction was that it did not have Lightbridge

    Which Drone; Phantom or....?

    I don't think that the Autel or the Typhoon H has Lightbridge but you can add better antennas to both

    Talk me out of the Typhoon H

    The height setting is not adjustable! However if you start above 33 feet it will fly home at that higher height.

    Does RTH work with Compass Error?

    You can fly to the home point based purely on GPS if you ignore the compass, but can you always safely ignore the compass when it does not agree with the GPS values?

    Which Drone; Phantom or....?

    I agree that the Typhoon H is an attractive option but be careful of the RTH flying height of the Typhoon H, manual says it is only 33 feet over home point unless you start the RTH above that height.

    Talk me out of the Typhoon H

    This thread appears to be concentrating on screen glare. I like the Typhoon H concept except for RTH, which according to the manual can not be guaranteed to fly over 33 feet above the home point if RTH is initiated below that height. Unfortunately I have trees around my flying areas that are...

    Storing Phantom 2 batteries

    Be careful to check your batteries regularly if you store at 30% charge since they discharge slowly. That is why I prefer to store at 50% charge.

    Storing Phantom 2 batteries

    In addition to storing LiPos at about 50% charge you should also keep them cool for long term storage. Avoid leaving them in hot cars or hot rooms. For long term storage I keep mine in a refrigerator.

    *UPDATE* P3P flips after only seconds in the air and lands hard in the water

    After a drone becomes waterlogged, disconnect the battery, and then shake out as much water as possible, gently dry it with a hair dryer, and then keep it in a warm dry place in your home for a week and the chances are good that it will function correctly. That has worked for me with an RC plane.
