I have had many emails with Mgm too, and they try to be as helpful as they can (taking a little language barrier into account), and always reply promptly.

My understanding is that we have to send our controllers in to get the update. After the controller is updated you will be able to do future updates on your own using your PC. Per Mike's message it looks like controllers made after Feb. 18th will have this update.

A little tip. Ship USPS Priority. I went to ship UPS and it was $108! I went to the post office and shipped UPSP Priority for $18. Remember to put a customs value under $15

Hey BashOn, did we have to put a little note on the box to explain the reason why we send it back the controller??

And what about the shipping fees when MGM will return back the controller to us?? MGM will return it for free???

The fact to put a customs value under $15 is very dengerous, because if the controler is lost in mail, you lost it....

BUT... if it's the curent fuse protection the problem in this controller, why not just use it in race mod with an external li-saver?????????

They did not say anything about return shipping. I did include a note with my address to ship it back and my email address just incase they need to contact me. Also make sure you put on the note why you sent it to them. I guess if they need payment for return shipping they will let me know.

You could certainly go with the setup you are talking about. Race mode with an external lipo cutoff. The better choice sounds like to set the controller in NiMH mode and leave the setting on cutoff (good idea jhautz). This way the MGM lipo cutoff is disabled but the over current protection is still in place.

If MGM is saying the problem is the over current kicking in to early not the LVC, then NiMH mode probably wont help the situation since NiMH just eliminates the LVC not the Over current cutoff. If the problem really is the over current, then race mode may be the only work around solution.

Good point. I guess if you used race mode and an extenal LVC you may not have the problem but I wouldn't risk it. Its a pain to send it in and wait but if your having the problem I'd say its probably worth it.

Notice how they implied that this is only a problem with some combinations (larger motor).

we tested this motor/controller/battery combination and we find this problem.
When avarage current (no peak current) go over the 105% of nominal current (current fuse start activate), can caused this mistake and controller save absurd value (and can cut off motor also).
