[QUOTE="msinger, post: 50879, member: 18"] The "Downlink Restored (after 0m 26.7s)" message means the Spark was not sending data back to the remote controller for 26.7 seconds. That doesn't necessarily mean the uplink [I](remote controller connection)[/I] dropped at the same time. RTH is initiated 3 seconds after the uplink drops. If we assume the downlink and uplink dropped at the same time, your log tells us the following: [LIST] [*]RTH was initiated before the downlink reconnected [*]There was a maximum time of 23 seconds when they Spark could have been returning home [*]The Spark ascended 54 feet and traveled 139 feet [/LIST] It doesn't. The Spark initiates RTH on it's own after the uplink drops. When RTH is initiated, the Spark will ascend to the RTH altitude before it starts flying back to the home point. The ascent and flying back are both part of the RTH process. No. You won't know the Spark is returning home until the downlink reconnects. [/QUOTE]
