Opinion on flashing ESC's for multirotors

I would like to hear some opinions on flashing ESC's

 

I've been reading about this over at rcgroups

http://www.rcgroups.com/forums/showthread.php?t=1513678

 

The main advantages, from what I read, would be that:

-the speed between controler and ESC is 8 times faster

-no more need of ESCcalibrations

-no more programming of ESC with programming card or TX

 

I'm using the plush 30A ESC's with the Atmega8 so reflashing it wouldn't be a problem.

 

Could this give improvements to the overal flight stability of Arducopter whenlooking at the update speed?

Hi Jashon,

In the code of the ACM, 

((timer - fast_loopTimer) >= 5000)

is this only need 5ms rate from ESCs?

Could we change it into 2000 for 2ms response?

Thanks,

-Duy

There will always be some sort of latency. It can be the motor prop combination with the airflow.

Maybe the frame is heavy?

The response rate ot a controller should be fast as possible.

There is a point of dimminshed return though.

A PID rate gain can adjust to a frame.

However if the frame is physically designed to move slow it will.
