If you are flying a multi point Waypoint Mission that has the H501A out some distance from the take off point and the H501A loses connection to the transmitter will the lost connection failsafe kick in at this point or will the H501A continue flying the way point mission?

I have tried this and lost connection and it appeared that it was trying to return to home on the lost connection. H501A FC 1.1.46 RX 1.1.50

There seems to be a difference of opnion on the various Groups on Facebook regarding this behavior.

I believe ( from testing) that the H501A or other waypoint drone will RTH on lost connection and terminate the Waypoint flight. Is this correct?

If in the middle of an RTH sequence from lost connection due to the pilot thinking that they can turn off the transmitter and that waypoints will continue without a controller. Although the mission is stored in H501A it has the information needed to fly the mission it is believed by some that the H501A will either A- continue with mission or B- RTH on lost connection? Which is correct a- or b ?-.

If the transmitter reconnects while in lost connection RTH failsafe will the H501A stop at that point and hover? In a noisy flight location precious time can be consumed wher landing the H501a may h av the Low battery failsafe. Another way to lose the H501A.True or not?

Some have suggested turning off the HT011A controller and APP during a waypoint mission and believe that the H501A will continue flying waypoints. This begs a definitive answer about lost connections and RTH. Will a lost connection while in Waypoint Autonomous flight continue on flying the mission or will lost connection protocol kick in?. I believe the latter based on experience. Please check with R&D to see which has precedence.

If in an RTH due to failsafe condition occurs and pilot turns off and on the transmitter will the RTH failsafe stop when the controller re-established connection?

Next question in waypoint mission definitions is there a version of the Hubsan app that defines a waypoint as a landing point? In all the missions I have done I cannot find a property like this for waypoints. Does one exist?

Last point of clarification needed. On a long waypoint mission with battery falling to 6.8 volts or below will the H501A land at the point of low power? This could result in a landing on top of a building, in the water, or on trees etc. if not worse.

Some pilots are under misconception that fly a waypoint mission and you can just wait for it to land itself without failure. As they set setup a mission and get some tea or coffee and you drone will be waiting for them when they come back. If there are no failsafes triggered it should be hovering at last waypoint waiting for landing control. But with Lost connection and low power failsafes I believe one can get into trouble and possibly lose a drone.

Another Series of things for manuals, Back to Basics or FAQs to address.

Please answer each of the 10 questions to clarify features and limitations of Waypoint flying with the HT011A + APP + Smartphone.These same issues may be present flying with the H7000 controller.

Thanks in Advance for researching my 10 scenarios and resultant questions

Happy Hubsan flying

With my 501a it definitely completed the waypoint mission before returning to home when it lost connection with my phone and relay on 2 occasions

1st occasion it lost connection at 1200m before reaching 1st point , thought it would come straight back but waited over 10 minutes before connection was re-established when it was on way home. Watched video and found it had continued to second and final waypoint before turning to home

I believe that if during a waypoint mission it senses not enough battery to get get home it will terminate mission and return home

Thanks for confirming. Great Job
You would think that Hubsan could have responded to this. Oh well I am thinking of leaving the forum. Why join a forum to get answers from Hubsan when very few are forthcoming?

Below is the response I received Aug 8th from Anne at Hubsan to an email sent re: this subject.

Hello. In answer to your questions.

1) We've observed conflicting testimonies to your question about whether the aircraft will continue waypoint flight after loss of signal. The specifics we will need to ask R&D about, but based on what the technician and I have both seen, it appears that the reaction varies from firmware. The latest appears to require RTH after LOS during Waypoints. Previous versions, however, prompt the aircraft to continue the mission even after LOS.

I can say that with Firmware RX 1.1.50 and FC 1.1.46 RTH does get triggered on lost connections. Since I don't have other firmware to test with I cannot tell you when the change occured. (JustJarhead0

2) If the transmitter reconnects while in lost connection RTH failsafe will the H501A stop at that point and hover?
I'm not 100% sure as I've not experienced this before, but it would make sense that this would occur.

3) If in an RTH due to failsafe condition occurs and pilot turns off and on the transmitter will the RTH failsafe stop when the controller re-established connection?
Yes.

4) Next question in waypoint mission definitions is there a version of the Hubsan app that defines a waypoint as a landing point? In all the missions I have done I cannot find a property like this for waypoints. Does one exist?
To our knowledge, no.

5) On a long waypoint mission with battery falling to 6.8 volts or below will the H501A land at the point of low power?
Yes.

Point 2
No , mine continued return to home when connection re-established

5 that's disappointing I thought it would realise it wouldn't have enough battery and cancel waypoint and come home
Will have to be more careful with my waypoints lol

Btw I've got a question about the app , iPhone has an option called guide next to poi but android doesn't , what does it do and why not ( don't have an iPhone to test )

MY updated Iphone app does not have that.

Ok , saw it on a YouTube video , they must have removed it .
