Hi there I’m a Litchi Newbie. I’m trying to use my Mavic Air to record footage on my jetski and figured that the Follow function on Litchi would be good for that. I’ve got a couple of questions 1. Rather than using the dynamic homepoint function I would like to use a fixed point so that the drone returns to that point when it’s out of power/ loses signal. It’s really hard to catch a drone on a jetski. Would using a fixed home point give me any problems 2. Is there anyway I can use the Iphone without a controller attached ? You can do that with the mavic air using DJI but I’m struggling to see any way to do it on Litchi. 3. Any other hints and tips for using Litchi over water ? ---

Spark, Phantom 3 Standard, Mavic Air/Pro drones that can only be used with a phone You don’t have enough drone speed to chase ---

The problem is that you don’t have enough range to fly the drone. ---

I think you’re better off using magic leash for this. And your friend to control the drone. But only for android ---

@David_Ness 1. Fixed Home Point should not give any problems. The aircarft will behave the same way as using the DJI-GO4 App. 2. During Follow Mode the aircraft follows the GPS location of your phone. This location is constantly transmitted to the drone. Since you don’t have the Enhanced Wi-Fi of the crontroller, chances are the drone will loose you much quicker AND Loss of control signal will occur much quicker in which case the aircraft will return to the Home Point. Theoretically it should work. 3. The downward sensors don’t work well while flying over water (Page 18 in the Mavic Air User Manual).

Thanks for these points. I did try Active Tracking in DJI, however it kept losing me. I wondered if using the Litchi Follow function would work better as it would be following a beacon . I should stress that I’m only going at 20 mph so the Mavic should be able to keep up ---

I use Litchi’s Follow Mode while riding my bike and there are no obstacles. While walking in a forrest I use GO4’s Active Track because of the active obstacle avoidence with APAS-2. ---

You can count on a speed of 28 . With obstacle avoidance disabled. No wind. ---

Oh this is excellent And with the sensors disabled, what is the speed? ---

But the problem is that the native application will not allow you to enable active track when the obstacle avoidance sensors are turned off. And litchi will lose the object at that speed. ---

It’s NO problem at all. The poster asked questions about the Follow Mode in Litchi. > [@bpa](#): > > And litchi will lose the object at that speed. In Follow mode Litchi will never lose the object, it may get out of frame, that’s all. I’m sure he will figure that out as he goes and lower his speed to below 17.9 mph. ---

The instructions say that the safe speed with the included sensors is 22. And the maximum is 28.8 ---

And also the author asked if it is possible to use only the phone. Yes, you can, but the range will be limited to 100 meters. In reality, 80 meters, but for a speed of about 50 meters. ---
