Hi,

I have the following questions about VOA that I would like answered:

* Does VOA respond differently depending on the speed of the drone? For example, does it kick in sooner if I am flying much faster from further away? If it does not, how slow do you need to be flying in order to avoid crashing into obstacles?

* What size of obstacles does VOA detect? For example, can it detect a telephone pole or a telephone wire?

Thanks! Looking forward to your opinions and answers.
