    hand launching

    I wouldn't hand launch. Catching is pretty safe because you back it to you in stable flight slightly above your head, grab it firmly, and shut down with one finger. It is completely in controlled stable flight. When you hand launch you will need to release it and then find out if it is in...

    Found drowned drone

    Yes, I did a 360 earlier in the flight to see how close I was to the trees on the other side but unfortunately did not before the fatal scan when I was flying sideways down the canal to pan the house. I wonder in the P4 would have picked up the mast and prevented it? I should get my hood...

    Found drowned drone

    I was flying my P3 from my balcony videoing my neighbors house across the street over the canal when I lost video and all contact with it. Several days later after failing to find it with snorkel using last video image, I read on here that DJI GO tracked the last flight with GPS so went to DJI...

    FPV using NVidia Shield K1 and airbuds (or other) goggles

    Battery life is no longer a problem with the Shield. I have had mine 6 months and use all three of my phantom 3 batteries and the Shield still isn't close to needing a recharge. I ordered the Head Play goggles and am expecting great results using the hdmi output. The Shield is the answer for...

    Drones not proven to be problem to airliners

    I agree, the small electric motors have parts much more dense that could cause considerable damage to an aircraft engines turbine. I am sure Captain Sully would have much rather encountered a drone than a flock of geese when he ditched his Airbus into the Hudson a few years back due to complete...

    Drones not proven to be problem to airliners

    The recent London Heathrow airliner incident striking a drone on approach indicates as most thought. Birds, hail and other aircraft are much more likely to damage an airliner than a small drone weighing less than 3 lbs. Maintenance found no damage and returned the aircraft to service...

    Speed vs Batt Life.

    True, as is fuel burn per hr increases with higher speed. My example of 10 mph vs 15 mph by increasing speed if you had 6 minutes of battery left you would go 1 mile. By increasing speed you may lose up to 20 % battery life so would have 4.8 min at 15 speed so would go 1.2 miles. Someday that...

    Speed vs Batt Life.

    I would increase speed returning with a headwind to get most distance. For example if you were returning into a 20 mph headwind at 30 mph your speed over the ground would be 10 mph. If you increased to 35 mph your ground speed would increase by 50% to 15 mph. Our airliners use this formula in...

    I don't hand catch anymore

    My first Phantom went for a swim when I took off from my dock and in a low hover, about a foot, decided to fly off the edge over the water about two feet lower and it instantly flipped over and crashed into the water. Obviously when the rotor blades over the water lost ground effect they lost...
