Chandruth replied to Randy's discussion ArduCopter-3.2 beta testing
"Hi Randy,
Who knows maybe the 0%-5% thing could help when landing on boats in rough seas or rivers. Thanks again for developing such and amazing code for Copter.
Regards
Chandruth"

"Hi Randy,
Take your time with it. If it comes to point there can always be a 3.2.1. Releasing 3.2 takes priority. Just thought a RC throttle 0%-5% check might remedy what users of X Aircraft flight controllers were facing. I was looking at it in a…"

Chandruth replied to Randy's discussion ArduCopter-3.2 beta testing
"Hi Randy,
If its the stability patch that doesn't go down to 5%, how about using the RC transmitter PWM values from throttle input. Use 0%-5% of calibrated RC Throttle PWM. This should be separate from the Desired Throttle to the motor mixer…"

"Hi Randy,
Regarding the landing detector checks, would it not be better to set the overall throttle<5% instead of 25%. Usually just before touch down you power down to idle anyway right. On the flight controller called X aircraft there are cases…"

"Hi Terry
I used the Autotuned gains then manually changed the Stabalize Roll/Pitch P gains. I have attached a screenshot of the gains. The PID Rate gains were from autotune. I only adjusted the stabilise P gains.

Chandruth commented on Chris Anderson's blog post New in the 3DR store: Bluetooth for APM/Pixhawk!
"So can we have an iOS ground station with Bluetooth as the Mavlink transceiver? I hope the droidplanner developers make an iOS app. "

Chandruth replied to Randy's discussion ArduCopter-3.2 beta testing
"3.2 RC2 has been great so far but I think Autotune needs to be improved to support large copters with large props and low kV motors. I fly a 830mm Quadcopter with RCTimer 5010 360kV motors on 6S with 17x5.5 props and the autotune is not able to tune…"

Chandruth replied to Erik's discussion Pixhawk Frustrations...this is a cry for help!!
"Hi
I used to run the same ESC on my pixhawk. The fix is very simple. Make sure all your ESC motor connections are connected to your PixHawks motor out ports. Remove all your props before doing this.
Step 1: Power off your copter.
Step 2: Turn on…"

Chandruth replied to Chandruth's discussion Pixhawk Collision Avoidance
"Do you think using two flow sensors is a good idea? Like use one of them for horizontal movement calculations while the second one is sort of used as a way to gauge depth and then use a comparison/estimation code to combine the sonar and flow data…"

Chandruth replied to Chandruth's discussion Pixhawk Collision Avoidance
"Thanks John. I am aware of the LiDAR project. 3DRrobotics seems to have a lot of interest on it. What I want to do is try and create close proximity collision avoidance as well as something like TCAS and Terrain collision avoidance for UAV's. I…"

So i decided to try Auto Mode on 3.1.2. But upon auto take off the copter  yaw 90 degrees from the waypoint heading but still continued to head towards the waypoint. When i noticed that this was weird i immediately came out of auto mode but then…"

"Hi marco,
This was with a fully balanced charged 3S lipo. The ESC setting are the ones recommended in the ardupilot website. It was working very well on 3.1.2RC1. Maybe I'll get my friend to pass me the crash log and post them here."

"Have to say the Soft mode feels exactly like Mikrokopter. Flew both and i could hardly notice a difference. Although my friends quadcopter crashed with 3.1.2RC2 when we tried to autotune, it suddenly yaw and…"

Other than sbus any chance of JR Xbus support being added. The link posted below shows that Xbus mode b is quite similar to sbus.

Having Xbus work on pixhawk will be a great help with…"

Recently i changed from 10x4.5 plastic propellers to 10x3.8 Carbon fibre propellers. After the change my quad always seem to oscillation in stabilise mode even after redoing the Autotune. I am also using the provided Vibration dampers with…"
