Glad for you guys that you have found a solution for your problem. A friend of mine uses a MGM 16018 (race mode as he uses A123 cells) and he experiences troubles with freewheeling. No matter if he switches it to on or off when he releases the trigger from fullspeed to neutral the car seems to brake for a split second. I also red some of you guys are experiencing a similar phenomenon. I'm wondering if this could be related to this current fuse. Otherwise he does not have any problems with power delivery. Anyone having a solution for this problem. I will try to auto tune his ESC and have a look if this could solve this last issue.

>When avarage current (no peak current) go over the 105% of nominal current (current fuse start activate)

Am i the only one wondering about this phrase. A MGM 22418 has a nominal current ability of 224A. What kind of setup is required to maintain 105% of 224A over a certain (undefined) period? Could it rather be it activates well below its nominal current ability. Just a thought. What matters in the end is that the problem got fixed. Guess they will see a lot of ESC coming back home to base in the next few days and weeks. ;-)
