If for some reason radio transmission is disrupted and never re-established, what is the impact on the arducopter (arducopter not in GPS nor Altitude hold running either on arducopterNG or the ardupiratesNG code) ... I mean will the copter drops from the sky immediately or it will continue to fly until it runs out of battery, etc., etc.
What type of radio?
R/C gear (most 2.4GHz and many on other bands) have failsafes that can be set to what you want on signal loss. If you don't have failsafe then I would expect a rapid crash on signal loss.
By rapid crash, do you mean an equivalent of the throttle control set to zero? Also, will signal loss cause the motors to disarm?
The radio system is Turnigy 9x ... a 2.4Ghz ... do you (and others) have any experience on how to set failsafe for the Turnigy 9x ...
You can programme the fail safe in the setting. Just programme you throttle to maybe 15-20 % or what needed to make the copter drop slowly.
You will find the fail safe programming very easy in the menu.
Thanks for pointing the FAIL SAF feature of turnigy 9x. Scrolled down to fail saf, click on menu, scroll down to THR,(which by default shows NOR), pressed the right arrow (screen now shows F/S 000%). Tried pressing menu quickly and I am brought to the previous screen. Tried pressing menu and releasing the button after a sec or 2, the transmitter just beep without doing anything.
Question: How do I change the 000% to the recommended 15-20% or any number for that matter?
To change the 000%, set the throttle stick where you need it, and hold the menu button down.
Thanks for the procedure. Yap, its just bringing the cursor to the 000% adjust the throttle stick then click on menu to see the percent throttle the stick is in, if not satisfied repeat the process of moving throttle stick and confirming with a click of the menu button. Pressing menu once more seals the deal.
Hey fellas, I'm a noob, and therefore I just don't get it. How would the failsafe work if it's programmed into the Tx? Surely it's gotta be programmed into the APM? If the TX is out of range, I just don't understand how it can save your AC from dropping out of the sky, like mine tries to do! Speak slowly, in prain engrish, I'd really appreciate your feedback :)
Good point ... I just assume some algorithm is communicated to the receiver when it becomes "paired" with the transmitter so in the event of signal loss, the receiver implement it as default ... that's just an assumption though ... anyone with a more definitive explanation is welcome to shed more light ...
