VPS with new FW ?

the only thing I wish is a way to specific the auto RTH when signal lost. 3s is too short a time. 5 or maybe even 7 is much more ideal or even better, allow a custom set range of 3s-10s
I have to ask.......why?

If you have lost control link what difference does 3,5,10 or 20 seconds make?

Any point in time if you re-establish link you have control of the aircraft back.
