"Hi Antonie, we've seen hectic RF and who knows what else around these types of facilities in SA, there are typically all kinds of Tx's pushing out watts of power so could easily be interference. At 50m AGL you could fly through all kinds…"

"the gradually increasing "circle" movement is related to bad compass data. it could be a local magnetic field, but a compass *can* be calibrated poorly, and yet fly apparently fine until heading is in a certain position. So you can do a…"

Can industrial infrastructure cause this failure?

Hi, We were out mapping a storm water channel around an industrial facility. The last mission was the South Eastern boundary witch passed very close to the plant. On approach to the plant the copter started to deviate from the auto path. I activated RTL and not being able to see if she was turning back, I switched the mode to Alt Hold and brought the hex home.Hex makeup:Pixhawk running 3.2.1FrSky telemetry system checking temp on power and motorsKDE motors and ESC's2xNEO8-MN GPS/Mag820mm center…See More

"Very impressive guys. I finished a big hex build about a week ago. KDE3510-475 motors and KDE35A ESC's. I mounted 15x5.5 carbon props with quick release bolts. I use 16A 6S batteries. I did a very small maiden just checking the stability. Next…"

"Ouch...I've just built a Talon 820 hex with 6 KDE3510's and KDE ESC's. I ran the calc around a month ago. I did maiden today...around 3 minutes checking that all seems sound. I'll put her through her paces over the weekend an…"

"Yes, I concur with TC3. I'm running a Wild Thumper 6WD with brushed motors and a brushed ESC controller. As long as your ESC's accept PWM there should not be an issue. The brushed motors 'humm' at the PWM signal from the ESC but…"

"@Niall, that's great. Made my day:) You should paint some spots on the robot and replace the beep with a bark - would sound less like a south African taxi and more like a herding dog. I like your design. Thanks for sharing. Antonie"

u-blox NEO-6P GPS chip
