"I'm going to purchase a "BM-785HB Servo Gearbox".
What gear ratio is recommended?

Thanks"

"Stefan,
Look in the "Full Parameter List" page"

"Simon,
My Mauch is plugged into power port 1 and it gave some way off reading until I entered the calibration settings that came on the little sheet of paper that came with the sensor"

DougB replied to Simon L.'s discussion Pixhawk 2.1 - issue with I2C2 port in Pixhawk2.1
"Simon,
Since the Pixhawk 2.1 mini power brick only handles 30amps I hooked a Mauch 100a power module on the power input 1 for the main battery that runs the motor and I'm using the mini power brick on power input 2 for the flight battery that runs…"

DougB replied to Simon L.'s discussion Pixhawk 2.1 - issue with I2C2 port in Pixhawk2.1
"I now have it working. I was under the incorrect assumption that the aispeed sensor static port was also providing barometric altitude data to the Pixhawk. But, the instructions say to set the ARSPD_BUS = 1, I can only make it work on ARSPB_BUS = 0…"

DougB replied to Simon L.'s discussion Pixhawk 2.1 - issue with I2C2 port in Pixhawk2.1
"I was just looking at the Libraries and the airspeed library has the driver for the MS5525 airspeed sensor but the Baro library doesn't have a driver for the MS5525. It's been a very long time since I was working with the development but I think…"

"1). I just confirmed that GPS2 uses I2C-2
2). I'm running arduplane 3.8.0rc5"

"Simon, try changing the I2C bus from 1 to 0 in the parameter config file, I just did that and the airspeed seems to be working
Edit: But Altitude isn't"

"Yes, I was just trying to setup one of the new MS5525 Airspeed sensors on I2C - 2 and it won't work. I'll have to make up a special cable to try it on I2C -1. Someone suggested making a cable to use the I2C bus from GPS-2 connector"

DougB commented on Chris Anderson's blog post New: QGroundControl 3.1 adds surveys and improved geofencing
"How do I get that panel to show up. On mine I only see the "H Planed Home position" and "S Survey" ? I've clicked all over the place and can't seem to find that panel.
Thanks"

DougB commented on Bernie Hoffman's blog post New Heavy Lift Prototype from Autonomous Avionics
"Do you have any video of it in flight? Also, some video from the camera in flight? How stable is it? How much wind will it handle?

It looks nice,"

DougB commented on Stefan Gofferje's blog post Arduino-based mode switch
"It looks like the X-Rock switcher has a analog output. These instructions show how to cut the wires going to a pot and connecting the switcher in place of the pot.

DougB replied to Randy's discussion Copter-3.3 beta testing
"Hi Leonard,
Leonard, Thanks for the reply

I checked the tune log before I saw your reply and, although I don't understand all the info, I could see that the starting numbers needed to be much higher. I increased the  Stab_P, Rate_P, Rate_I…"

DougB replied to Randy's discussion Copter-3.3 beta testing
"3.3rc11  , on a 3dr X8  I did Roll and Pitch individually and they completed ok. When I try to tune YAW it takes over 6mins and does not complete. I run out of battery and have to land. I land by switching to stabilize while leaving CH7 on in…"
