You can look at the same discussion for those with an Android device that have purchased Litchi. I purchased Autoflightlogic Autopilot because I cannot fly manually by myself while documenting a $7 mil. Malibu Mansion as well as this program does. Waypoints beta teasers have been surfacing but is not out today. The first paying job, you have recovered your investment. For NEWLY, if you are launching at your home and expecting to fly out over 1 mile, you are approaching the limits of your P3. I would plan on going to the middle of your property and flying your grid pattern only 1/2 mile away at any one point.
msinger: Zipline, the waypoints feature will allow preflight programming as all modes do and events to occur at each point, the follow mode allows for 4 directional offsets along with elevation adjustments utilizing the barometric capability of the ios device.
