Jiro Hattori replied to John Mulligan's discussion Px4 Testing"In my personal opinion, the issue of PX4 is flexibility of each port and function.
1) The serial port is changing booting and normal process.
2) The order of SRV1-4 outputs also different. ( in dev discussion "Px4_Fmu servo 1-4 outputs do not…"

I'm living in Atsugi. It looks like lots of space to fly air craft in Atsugi. However, there are very few places to flay.
