    P4 Return to Me (not to home)

    Be careful changing the home point during flight. There have been several reports of the new home point location not being recorded correctly. If the home point is in error and happens to be outside of the maximum flight radius that you have set the drone will immediately start flying toward...

    Distance / "Fuel" Ecconomy

    I'm sure there is an optimum flight speed to achieve maximum range but I don't know what it is. I've been meaning to fly a mission at various speeds to see if there is a "sweet spot" in terms of speed that gives the best range. Any calculation like that goes out the window though is you're...

    Was it litchi or the IMU?

    Also keep in mind that if your takeoff point is at a slightly different elevation that will affect altitudes.

    Those are your sheep, right <g>?

    Flying from inside house or car anyone?

    I assume that you are referring to my post. The site works for me, l-com,com. That's lower case L and a hyphen at the beginning.

    Litchi mission and no-fly zone

    Hmm, ok good to know that it will not start flying the mission. I had visions of my P4 stopping in midair halfway through a mission while out of RC range. So does this apply to the 3 mi restricted area around smaller airports (that you can override with GO app or just the large airport full...

    Litchi mission and no-fly zone

    I have seen this asked but not answered. What if you inadvertently plan a Litchi mission that strays into a no-fly zone? What does the phantom do? Could be unpleasant if the answer is "hover" and the aircraft is out of range of the RC.

    Litchi landing question

    Hold left stick full down for 3 seconds after landing or catch.

    Litchi waypoint rotatation action

    Impressive and ballsy flight. I liked the one where you got really close to that building also.

    Need Some Help with Litchie - Missons stalling just beyond controller range

    You are in waypoint mode? And you have uploaded a mission to the P4 and started it? There is a setting for behavior on loss of signal while manual flying, and you can select land, hover, or rth. That shouldn't affect what happens during a mission but you may want to check it anyway.

    Itelite with amps and maxx range antenna question??

    These are receive only, no transmit. Only useful for the peceive-only port of the RC, with a standard booster on the TX/RX port.

    Itelite with amps and maxx range antenna question??

    A booster is helpful in certain situations. You can definitely increase the transmit signal strength with a booster, no question about that. The problem is that fpr most situations you need to help the receive side as well. For receiving the booster is just acting as a preamp, and yes it will...

    Itelite with amps and maxx range antenna question??

    I have wondered about using an LNA on the receive-only side rather than a booster. This is a bare-bones possibility: 2.4GHz Low Noise Amplifier LNA 2.3GHz ~ 2.5GHz SMA Or these: 2400-2500MHz 1.5dB NF Low Noise Amplifier, LNA-2450,SMA 2400-2500MHz High IP3 LNA, NF=0.85dB, LNA-2425,New, SMA

    Yes if you have good LOS you are home free, but a lot of folks don't have that.
