"I agree with Chris - found that out last night while having difficulty in getting the AC2 HILS running. When in doubt start from scratch (I don't even use old setup files - just in case)

"Hi Gareth, I got -17.32 for Pretoria - entered it like that and looked at the Flight Data page while rotating and turning the quad - looks within 10 deg to my untrained eye. Now I guess its up to flight testing...

Jaques Viljoen replied to vaeddyn's discussion PID tuning for 12" instead of 10" props
"If it is quick oscillations you can decrease the Rate P value, if it is slow oscillations you can decrease the Stabilise P value. Remeber to adjust both the Roll and Pitch values :-)
Friends of mine also went to 12" props and found exactly the same…"

Jaques Viljoen replied to Jaques Viljoen's discussion Delayed switching of Modes
"I think I may have found the solution to my problem -For all my flying I use a Hitec Eclipse 7 transmitter with a Fr-Sky 2.4GHz TX Module. When doing HILS testing I found the unpredictable Mode switching and rudder lockout. However, I then tried a…"

Jaques Viljoen posted a discussion
I have experienced a delay when switching from Alt_Hold to Stabilize and this caused a little crash. The funny thing is that it 'feels' like the same type of lag when the rudder commands become unresponsive.I have logged an issue here:…

Thanks to everyone involved"

Jaques Viljoen commented on Chris Anderson's blog post New product in the DIY Drones store: the DroneCell GPRS board
"Hi, my interest is using a module like this to transfer telemetry from my uav to the gcs instead of a pair of Xbees. My only interest with this module is internet via gprs for the least cost method as well as the highest bandwidth. But I'm not sure…"
