same problem

I have the same problem, how do I fix it?

[Gen]

even though i havent one of thes esc out of intrest i wrote a email to heifi support explaining the problem here is my reply

Thanks for you interested in our products, Please try with the following methods to deal with the issues:

1 Solder another capacity pool to increase the value of total capacities.
2 Make sure the length of wires between motor and ESC is less than 80mm.
3 Make sure the ESC is far away from the receiver as possible as you can.
4 Use the separate battery pack to power the receiver and servos.

I think none of the above is a definitive solution.
I think the error is not interference, and the solution he gives is as if the error was interference.

i will prove it in the future, so far this drive is discarded

Has anyone used this esc 200th with 6s and its bec?

[ray schrauwen]

It has no BEC.

[Steven Vaccaro]

It has no BEC.

It has a bec.

I haven't been able to duplicate the problem they are seeing. Maybe a video of the issue can be done on the bench?

Latest SF240HV firmware( from HiFei ) shows the run-on fault.
I installed this to a beta and the result was terrifying.. it ran on for 1-2 second WOT when it should have slowed for the corner 100ft before !
Also on SF240HV, thermal cutoff has no registration from sensor.
Original supplied firmware did not display this.
Script suggests this is a delay due status change from active signal recognition to failsafe condition... it needs a certain qty of valid command sets before it alters staged output.. but the script screws up the delay.

Am in dialogue now with Michelle ( HiFei) regarding this flaw.

Please post the version of the firmware that has the problem so I can check my two ESCs (new SF200LV's).

early batch ESC#1 firmware AHiB 0730 00MC 2000
recent batch ESC#2 firmware AHiB 0B10 01MC 200L

AHiB 0B10 00HC 240L for the SF240HV as released 08Jan2011
with variable LVC settings
Software is not interchangeable between platforms.

eg 200 =X= 240HV !

[drwayne]

I have have not written for, not ever seen, the 200LV
Show me where Steve hides the downloads, and I will have a peek at comparability...
However I doubt a 26V limited hardware will survive the 51V control set of the HV.

As control errors are ghosted between 2 platforms, one assumes some scripting routines were cloned.

You can download the Version 2 executable here:

"New Program Box" ???

Thanks for the links Insaniac.

[ray schrauwen]

Will these be back in stock anytime soon?

[Steven Vaccaro]

I have confirmation that the order is finally on its way. The long Chinese New Year messed up many of my orders. I hope to have it by the end of this week.

[drwayne]

After beta testing V3 software, I understand the new batch of hifei esc will arrive with that firmware.
This has a crisp response to throttle... 2 second pause to reset failsafe, and a few more tweaks

Thanks Wayne. Now can we update the previous versions?
