Respond time quadcopter
« on: January 29, 2016, 07:22:09 pm »
Hi,
I have a 270mm carbon fiber quadcopter with a CC3D flight controller. The thing is when I go to right (for example, left, front and back are same) and immediately I go to the left, the quadcopter take about 1-2 second to go to the left. How can I fix it ? I need a quick respond time.

PS: I'm in mode 1

This latency looks strange :)

For left/right are you talking about Yaw axis ?

Please post your config file: File > export UAV settings

Thanks for your reply, I'm not talking about the yaw, but the right stock on mode 2 transmitter (left / right and forward /backward)
Here is my parameters.

Thanks for helping me

- There is something strange with one motor neutral, look Output tab.
- Start using same bank for all flight modes.
- Keep default values (Attitude response is reduced in bank1)
- Try to tune PID using EasyTune.

-I know for the motor, but if i put about same value of other, it not work.

-I keep all default for bank 1 i will try
-What is the PID ?

You think something is wrong with my quad ?

Redo the Esc calibration... this neutral looks really strange.

https://fr.wikipedia.org/wiki/R%C3%A9gulateur_PID

PID defines the stabilization response but it will not take 1 or 2 seconds to move using default settings.

How feel your quad ? Under-powered ?
Where is the Throttle stick when hover ?

I try to recalibrate the esc, i will see tomorow if it change. But for you it's a esc problem ?

Not sure... but all esc are calibrated at same time, you should not see this difference from one motor to another.

HI, i have try many things, but on mode 2 the response time was better. Can you send me your setup ? Your response time is good ?

Whats the mode2 ?

I don't have any issues with something like 1s latency... :)

Never mind. So do you want it to respond quicker/more twitchy. Is that what your after. Are you in auto level. Are you saying you push the stick forward and it tilts forward and it takes a second to start really picking up speed? What exactly are you asking.

How to know in which level I am ? Yes, for example if I go to the left and immediately I want go to right (not the yaw, haven't try yet) it takes a little time to go to the right. In the first mode is very low, and in the second mode (intermediate) it takes less time, but it's not almost immediately.
