Hi all,
I've found that the Multiplex DS IPD receivers that I like to use have a maximum failsafe time of 30 seconds.
For UAV flights on the fringes of radio range I would prefer to turn off the transmitter completely and have the receiver hold the autopilot enabled.
In the case of the MPX units they stop outputting a PPM signal after 30secs but the autopilot stays enabled based on the last good frame received on the enable input. However I'm concerned of stray RF causing a disable signal on that channel.
Ideally I'd like a receiver with unlimited failsafe time, addressing similar to that used on 2.4Ghz (for a degree of protection against outside signals) and 35Mhz operation.
I dont want to use 2.4Ghz control due to the reduced range and the fact that I want to use a Xbee Pro for realtime tracking.
