John replied to Randy's discussion ArduCopter-3.2 beta testing
"Hi Randy,

David is right, I also experienced this. It is currently not possible to enable the MB1240 sonar using the latest firmware on an APM using the latest mission planner.

John."

"Hi,
 
HDOP says nothing about the accuracy in case of having reflections or Multi-Path reception.
 
HDOP is only based on the position of the satellites received which determines how accurately you can in theory calculate the position if and only if…"

John replied to Randy's discussion ArduCopter-3.2 beta testing
"Hi,

I tested both 3.1.5 yesterday and 3.2-C2 today with a standard 3DR hexacopter with APM 2.6.

I only flew in Stabilize, Loiter and Hybrid. It all was ok. Then I wanted to look at the logs which gave problems:
1) I cannot get to download the logs…"

"Hi all,

I have been playing around the last 2 days with the auto tune feature of 3.1 RC-4.
I enabled autotune and compiled and downloaded the code. Autotune is working (see attached log).

John replied to John's discussion Please help in setting up 3DR ESC's
"Hi,

spread the word to others who may need the manual, we have it now.
 
Maybe it is a good idea for 3DRobotics to actually send this file with their ESCs so people know what they have bought.
 
Regards,
 
John."

"Hi all,
 
3DRobotics finally informed me which brand of ESCs they relabeled as 3DRobotics.
 
I have contacted the manufacturer, and they did sent me the original manual.
 
This behavior is in my ESCs by 3DRobotics indeed, so now I know how to…"

"Hi,
 
You can easily detect whether you have the SimonK flashed. If you enter throttle calibration and then don't lower the throttle stick, the non SimonK ESCs will start to make all sorts of sounds allowing you to go through setup menus. The SimonK…"

"Hi,
 
Let me start with saying that I am amazed how far you all brought it with both the mission planner as well as the APM!
 
I have had a problem with the 3.01 version in a new RTF Hexacopter from 3DRobotics.
I bought it completely built just a…"

Hi all,Let me first state that I am amazed about the SW that has been created by you all, both the GS as the flight controller! I have bought the 3DR Hexacopter a couple of weeks ago and did all the setups. It was flying nicely. The other day though…
