A lot of students ask me what happens if you lose signal during a mission. Well the answer is 2 things can happen and the 2nd affect might surprise you!
Check out this video to find out the answer ...
This video covers some of the more important items in the various Litchi updates over the period of May to August 2017, such as AFC (Autofocus continuous mode), Tripod mode, the on-screen Stop button and support for the DJI Spark
If you fly a lot or run a drone business then you are going to want to get an account with Airdata.com.
Its free but you can get paid options too.
The beauty of this service is it automatically syncs all your flight data into the cloud and gives you actionable intelligence at your fingertips. No more pen and paper at the flying field and wasting precious time and energy doing log keeping. AirData will do it all for you.
In today's blog I discuss how Airdata provide an easy way to sync with the flights in the DJI Go app and this is especially useful for those with a Phantom 4 Pro + drone which could not use Airdata until now.
As always happy flying
Do you experience any of these symptoms when using Litchi:
If you are experiencing any of these issues then it might be your mobile device.
The reason for this is most likely the DJI SDK (software development kit) which 3rd party app providers use to develop their app for DJI drones.
In July 2017 DJI released SDK 4.0. This latest SDK is the most demanding one yet. For example the Nexus 7 worked without issues on the previous SDK, but on SDK 4.0 the Nexus 7 struggles.
According to Litchi they tested the following devices, using a Mavic Pro with the latest DJI firmware (results may vary with other drone models):
- Nvidia Shield Android 7: OK
- Galaxy S8+ Android 7: OK
- Galaxy S6 Edge Android 7: OK
- Galaxy Note 5 Android 7: OK
- Galaxy Tab S2 Android 7: OK (can have some connection issues depending on model)
- Galaxy Note 4 Android 4.4: Not OK (a lot of lag)
- Nexus 9 Android 7: Not OK (way too much lag)
In the above list the 2 slowest devices (note 4 and nexus 9) used to be OK before SDK 4.0.
It seems that the SDK is more demanding on Android then iOS.
Litchi have not published a detailed list but the above Android examples are an idea of what will work.
iOS devices they recommend are: iPad mini 4, iPad 2017, iPad Air 2, iPad Pro, iPhone 6s or anything higher.
In general they recommend at least 2 Gigs of RAM. Also the software version makes a difference as the Note 4 above had issues but it ran on Android 4.4., but my Note 4 on Android 6 runs fine.
To improve the performance of your mobile device, please follow these guidelines:

I am sure like me you enjoy creating a lot of missions. And sometimes the list gets so long that it becomes annoying scrolling through them and you are tempted to delete them. Well I do the same thing, but before you delete a mission you should back it up.
Watch this video to learn this very important tip and make it a habit
In the last blog I discussed how I approached a shoot. Its now time to look at how it went, what I learnt and what I can share with you.
So it went mostly ok. The big issue that has cropped up is I shot the drone footage in 30p (my personal preference) but my client who did the ground based video shots used 25p and it turns out trying to get them both into the same production is a pain in the ass. So tip 1: ask your client what frame rate they need to work in and use that.
The next issue is I assumed I would be able to use Litchi, but in fact because it the section of the warehouse we shot in was very deep under roof, there was no GPS and Litchi went out the window. Tip 2: If you plan to use Litchi make sure you will have GPS
Luckily I shot with the P4 Pro and its very stable indoors even without GPS and therefore I could fly very comfortably. The client asked me to do some very low shots, like 2 feet off the floor and look up at this giant contraption as I flew past it - great idea except for the huge amount of dust that got blown up: Tip 3: If the floor is very dusty wet it down first
I then decided to use Tapfly to shoot some smooth Flyby shots. The problem is that you cannot disable obstacle sensing in Tapfly, so when I got near this giant object the obstacle sensors went nuts and the drone slowed down and I lost that smooth continuous momentum. Tip 4: When using Tapfly remember you can't disable obstacle avoidance and therefore obstacles will cause you to slow down or stop
Then I took the risk of flying through this giant metal hollowed out tube as the client wanted a fly-through shot. Flying through a metal object is a very bad idea as on the first occasion it went fine but the second time the compass went nuts and I started drifting and lost control but luckily got out without a crash. Tip 5: avoid flying through anything that can badly throw your compass especially when the money you are making from the job does not justify taking risks
Then the client walked with me as we did several shots and he kept looking at the drone and I kept saying look at the monitor: Tip 6: tell the client to look at the screen so he can be sure he is happy with the shot. And remind them during the shot.
Well it was an interesting shoot and I wish I could show you the footage but its a very hush hush project and I am not allowed to.
I hope my tips help you out and please share or comment on this as much as you like
I have a shoot tomorrow of a gigantic piece of industrial machinery and after having done a site inspection I sat back and visualized the shots I think I can get (safety is key as crashing inside a poorly lit warehouse is a risk). So I decided to make a short video showing you my shot checklist and the reasoning behind it. I hope you enjoy.
I am not sure if you have seen this video (scroll down). It is a wake-up call for all drone pilots. This poor lady crashed an Inspire into the side of a boat and then into the sea. I posted this on the Phantom Filmschool Facebook Group and I got reactions from many students. some of the students are seasoned sailors and gave good advice for trying to land on a boat.
The main moral of the story for me is not following basics. and by that I mean ALWAYS taking off and landing in forward orientation and not reverse orientation.
It is obvious to me in this video that this pilot would have had a much better chance of a safe landing if she was flying in forward orientation.
The reason for this is simple. When landing your drone manually your brain is managing many things. Wind, weather conditions, bystanders and the noise of the drone and its proximity to you can increase your adrenal levels. Then add a moving boat and an expensive drone into the picture and adrenal levels go right up. Then do this in reverse and your brain is just about overloaded. By landing facing forwards this would have been tricky but doable.
As always keep it simple and practice the basics so when you panic you have rehearsed what to do
