"Increse your landing speed. The higher the landing speed, the earlier the motors will cutoff, and less bouncing. The key is to find a sweetspot between acceptable landing speed and motor cutoff."

Hi Everyone, I have the Feiyutech 602 data modems. These are 500mW 433Mhz Radios which are very light and provide much better and longer range than 3DR Radios (approx 10kms and more). Today, I got an…Continue

Can we expect similar performance with that of DJI on 2.9.2 ???
With due respect to all the contribution of the developers and testers, DJI is still way ahead... in terms of filtering, smoothness and performance...
Asking this as much of…"
Saurabh Srivastava replied to Randy's discussion ArduCopter 2.9 / 2.9.1 released"If you reduce the landing speed way too much kike 20 or below, the motors would not turn off easily upon landing and your multirotor will keep bouncing on the ground... lol

Saurabh Srivastava replied to Randy's discussion ArduCopter 2.9 / 2.9.1 released"Randy, Leonard,
Any update on the 2.9.2 ???
I believe most of the issues in 2.9.1 will get ironed out with 2.9.2"

Thanks."
Saurabh Srivastava replied to Randy's discussion ArduCopter 2.9 / 2.9.1 released"Hi Randy, Here is my raw log file. Do you feel that there is too much vibration? Not very sure how to interpret... I have the APM 2.5 mounted on the o ring suspension. Please help interpret. Also, as I had told you earlier, my COMPASS_OFS_Y keeps…"

Elvis replied to Saurabh Srivastava's discussion Decend Rate - ArduCopter 2.8.1"Andy,
Are you still using Sonar? I'm interested in the Autoland feature and am thinking of picking up a sonar unit. I've heard they put out a lot of EMI, have you had any issues with that?
Thanks,
Elvis"

"Hello,
Do you use the ubec to power the APM and if so do you have a seperate battery for it.
And do you use the ubec on the servos as well? or do the servos have their own battery?
Regards
Christiaan"

If you have a choice now what will you choose FrSky or OrangeRx?

Saurabh Srivastava replied to Randy's discussion ArduCopter 2.9 / 2.9.1 released"Hi Randy,
This is what I did.. As I told you that my COMPASS_OFS_Y was way too much, I reset COMPASS_OFS_X, Y and Z values to 0. Enabled the COMPASS_USE and the yaw drift i spoke about was gone. However, the COMPASS_OFS_X, Y and Z values…"
Saurabh Srivastava replied to Randy's discussion ArduCopter 2.9 / 2.9.1 released"Thanks a lot Randy. Appreciate your time.
My COMPASS_OFS_X, Y and Z values were quite large. Infact the Y was 342.44 which is fairly large. Does this increase with magnetic interference by wires motors etc? I reset them to 0.
The declination…"
Saurabh Srivastava replied to Randy's discussion ArduCopter 2.9 / 2.9.1 released"Thanks for your time Alexey.
The power cables are away from APM. Infact I have kept all cables as far possible. This problem was not there in 2.8.1 with exactly the same setup. What else am I missing ?"
Saurabh Srivastava replied to Randy's discussion ArduCopter 2.9 / 2.9.1 released"Randy,
Could you please explain the parameter "COMPASS_USE"
I have a peculiar problem. When I fly with "COMPASS_USE" set to 1, the copter automatically Yaws 20-25 degree. Also, in the Stabalize mode, the copter…"
Saurabh Srivastava replied to Randy's discussion ArduCopter 2.9 released"Desperately waiting for 2.9.1 followed by 2.9.2"
Saurabh Srivastava replied to Randy's discussion ArduCopter 2.9 released"Thanks Leo. Will start off with either 25 or 30 cms.
Just wondering if Randy could default the Landing speed to 30 in 2.9.1 as it seems to be more apt and practical."
