    I do not own an Inspire 1, but rather a P3A that I am using as a learning tool. Recently I acquired 2 3rd party applications for iOS in support of the Phantom: Litchi and Airnest. I recently ran a test of the POI function of the GO app and I was disappointed in the results. Airnest seems to be a bit smoother. Here is a video illustrating this:



    My question is this: Since the camera on the Inspire can pan 360 without the aircraft having to yaw, is the POI feature in Go smoother on the Inspire than it is on the Phantom?

    Thanks!

    I've used POI many times with my I1 and P3s. In that mode the I1 camera is locked in the angle and direction of the POI and the maneuver is done in exactly the same way as the P3.

    No problem, the POI function on both is somewhat clumsy in my opinion. It always looks weird when they start the POI mode by lurching into the flightpath and I've also noticed they don't always fly in perfect circles.

    Yeah I think my video illustrates the issue pretty well.

    Honestly, I would imagine you will generally get better functionality for those very specific use cases with the more focused third-party apps—Vertical Studio, Autopilot, Airnest, etc.—simply by virtue of the fact that those apps are going to be spending all their development time and resources on those features.

    After all, those features—POI, follow, etc.—are the entire purpose of their app, rather than just a bullet-point in the feature list as with DJI GO.

    My video illustrates Go vs. Airnest. Will be doing the same for Litchi this Sunday.

    To be honest, how long do you want the drone to circle? Going by your clip, I would simply shoot at the lowest speed and speed up in post. I dont see the need to spin as fast as you are trying to do here. I would even shoot at 50fps and go to 25fps in post. Not a problem.

    It was sped up to better illustrate the unstable nature of the footage.

    Don't know if you have seen this one.
    Autopilot - Autoflight Logic
    I have this app, but have not had the chance to test it as of yet.
    I do believe it does take advantage of the Inspires ability to rotate the camera.

    Why? if its stable a speed you want, why speed it up?

    To better illustrate the issue in the video...

    I performed a similar test and app overview for Litchi on iOS here:
