Hello Guys,
On 01/03/18 I sent back my spark to the store where i bought the drone (MSI-ECS Philippines) for warranty claim.
They sent a ticket report to DJI and on the same day and DJI replied the day after informing them that my claim was denied due to pilots error.
I just felt that my side wasnt fully defended by my local distributor so I sent an appeal email directly to DJI support on the morning of 01/04/18 but up until now I havent received any response.
The Crash Story
I have my usual flight in our neighborhood, most of my flights are in this area and that includes my last 3 fligths so i didnt even bother to calibrate the IMU and compass. That being said I still did my pre fligths rituals which is checking the GPS,IMU,compass and wind. After around 10-11 minutes of flying I decided to take off my spark.
Since a bunch of people began to stay at my original launching zone/home point I decided to land few meters away to avoid unexpected injuries to people due to unforseen accident. If you would check my previous fligth logs in my account I usually land to this same area, i think it would be around 10x already so theres definitely no inteference at all.
While doing the landing if you would check the fligth log I am just holding the down button. Unexpectedly 1 meter from the ground the spark began to initiate RTH as the battery hits below 20%. It gained few meters of elevation, spark also began to swing left and rigth. This causes the spark to hit some small twigs. It losses elevation and did the same thing again and unfotunately hits another small twig . While all of this is happening all im pressing is the cancel the RTH, some left button to avoid the obstacles and down button in my RC and phone but my spark is not responding at all.
After hitting the 2nd small twig I was shocked cause I saw the battery fell from the ground first. Then of course the spark crashed and bounced to a small stagnant fresh water. The battery was dry after the crash but a small portion of the spark became wet after the crash. I am not sure which part of the aircraft became wet but definitely its only a small portion since the crash site is a small area of stagnant water only. Battery was latched out mid air so definitely no there damage is no damage on the circuits inside since the drone does not have any power on.
I sealed the spark in a box with a bunch of silica papers/gels to absorb the moisture. I still havent tested the drone after the incident cause im afraid it may worsen its condition.
1. Spark fails to land even though its only 1 meter from the ground
2.The cancel RTH button should be functional all times. This button is vital to avoid such accidents that may happen. I believe the error was caused by the recent updates in the DJI Go App.
3. The spark almost got away with the obstacles however the battery latched out on mid fligth. You can see this on the fligth log.
I believe all of this happens due to the recent updates from the DJI GO App plus the known battery issue with the spark.
I will upload the fligth log later once i got home.
I do hope admins can help me T_T
