Subject: Decrease telemetry rate on the pad to 1/sec instead of 20/sec
X-Git-Tag: 0.2~14
X-Git-Url: https://git.gag.com/?p=fw%2Faltos;a=commitdiff_plain;h=e9584e846b9bd7926d61451d32ba5d7a30416f7b

Decrease telemetry rate on the pad to 1/sec instead of 20/sec

Transmitting telemetry through the radio consumes a significant amount of
battery; reducing the rate to 1/sec will reduce power usage while waiting
for launch.
