I'm setting up a Skywalker with a 1.4 APM and the 2.5 firmware. Could someone tell me what initial parameters to use for the airframe? With all the changes lately, I'm not sure if the skywalker.param in the repository is a good starting point…

Mark Peterson replied to Mark Peterson's discussion Altimeter deviations
"Just to close the loop, I definitively determined that the source of the altitude deviations was due to the XBee by removing it and hooking up to the autopilot via USB. The altitude readings were quite steady w/o the telemetry module.

Based on tips…"
