"What's the little black box on the top? a wifi module?


No, Cala. This cube is the Pixhawk 2, plugged into the daughter board."

"Confirm. I did around 90 batteries since february on my sample builds F450,Robocat 270 and Cheerson CX-20 mainly with PX4 and I didnt notice hardware issues. One demo of feb.

"I used the live calibration as well (since I didn´t know what the onboard does) Auto Accept always finished far too early (after 180°),turned it off but still had a lot of calibration failures till I got it finished.
It always showed Err 99 for the…"

"1. The EKF status window is reporting partly heavy movements (Mainly Velocity up to red , Pos Hor/Vert,Compass a little) while the copter is setting on the balcony desk (@ low HDOP <1) .
2. The MAG calibration is working for all compass, (turning ba…"

"You´ll be able to measure Voltage w/o arming the motors with the ACSP4 as well :-) Voltage measurement is done by a simple resistor divider (which requires diff. setup depending on FC)"

gervais replied to Randy's discussion PixRacer with Ardupilot
"Yes. Works well for me with these settings :
Keep in mind: Voltage calibration w/o load and current calibration should be done with a hi amp load (e.g. couple of Halo bulbs) Don´t expect proper current readings without load. This is not meant to mea…"

"Philip,Tridge:  Thx a lot. Very nice, my first copter with 3 MAG . (2 internal and one external)
Could you please explain:
1. Does v4 APM use all MAG if enabled ? (Averaging ?)

2. Redundancy ? Switchover during flight in case of a failure ?"

"No matter what you paid, the sales result will be a dissapointment today. Sell your add ons separately and be happy to get 300$ for the IRIS. Ebay is full of nice offers, e.g.

"My r14 board has Probs with Hott (Graupner) PPM as well.

Calibration works fine, but RC Receiver message appears quite often and Failsafe ´s getting engaged. Probs with 3.3.4 (Pixracer stable), as well as with current master. 4/6/2016

And no, this…"

"1. The ACSP5 is coming bare, w/o the wire harness, battery cable , or distri board since most users have their own requirements, application related. However, the Pixracer kit includes 2 cables JST GH, one 35mm, the other with 150mm, as shown below.…"

"Sorry , didn´t realize, that you´re new. The so called GPS cable for 3DR GPS+MAG can be used for latest 3DR telemetry as well. Same pinout. Works right away.


So if you need two, just order a second one. If you want to operate with RTS/CTS as well…"

"3DR radio cable is included (JST-GH 6 Pin > DF 13 6 Pin), or available @ AUAV.co for a bargain price.  I connected mine with it . (The case of the 3DR air module V2 is stripped, a 3DR IRIS leftover)"

gervais replied to Paul Harris's discussion Low Price Pixhawk units out of China, anyone know anything about them in PIXHAWK
"As DG stated, some are clones of the PX4v2 Gen, (1:1 copies), some are derivates (about same components / concept) of it . Pixhawk 2 is v3 gen, Pixracer is v4 gen."

gervais commented on PX4's blog post A detailed look at Pixracer
"They are standard Dupont connectors, usually coming with Servos and ESC. See them at the Pixracer Instructions page pics on http://px4.io/docs/pixracer/"

gervais replied to Chloe Griffiths's discussion Question about drones- any experts here?
"I´m sure, she needs help. But from other experts who will probably recommend to double the Risperdal or Seroquel dose."
