Why is the flying time different in the mission hub and the new litchi hub? 7min30s versus 11 min! Same parameters: speed and distance!
With the old Litchi Hub, I noticed that all waypoint missions with a flight time exceeding 15 minutes would arrive precisely 5 minutes before the expected time of arrival. Flights that lasted less than fifteen minutes, on the other hand, arrived at the exact time implied by the on-screen mission duration.
For example, given a waypoint mission whose flight time was showing as 20 minutes in the old Mission Hub’s screen, the drone would arrive exactly 15 minutes after the moment of its departure on the waypoint mission. I assumed this over-estimation of flight time was deliberate, to include a 5-minute margin of safety, which I took into account with my flight planning by creating waypoint missions that lasted 5 minutes longer than the actual flight time I wanted the drone to be aloft.
I only recently started using the new Litchi Mission Hub, and haven’t got around to comparing the theoretical flight time of waypoint missions with the observed flight time. To avoid running out of battery power, I have gone with the assumption that the 5-minute flight time discrepancy has not been carried forward to the new Mission Hub.
The legacy Hub time estimate was inaccurate, but the new Hub should be relatively close in general
Just like to add some info which may help. Any app I’ve used can only give an estimate since the app cannot take into consideration things like which drone you’re using, the environment which especially includes wind. Even the time it takes to get up to the set speed initially as well as every time after slowing down for corners then back up to the set max speed can be a factor. Depending on which drone the power is different to include the acceleration rate. As Vico said the new Litchi hub should be relatively accurate so if it’s way off then maybe there is an issue so I’d check to see if it’s close.
Overall my missions which I have run over many’s years are relatively close to the estimated time. If it’s a minute or two different then I call that about as accurate as it can be. Also the estimated time is from the start of the actual mission to the completion of it. It does not include from take-off and the approach time to the start of the actual mission as well as the return time. If you add a take-off point in the plan you will see the mission simulation only shows the time from start of the mission to the end, not from where you launched the drone or the return. Something you may want to take into consideration. Enjoy.
