    Just went thru 3 blx esc fans and within a few jumps THEY ALL wound up with one missing fan blade causing a loud humming noise. Anyone else experienced this issue before?:confused:

    I wonder if you can add a spacer between the fan and the ESC to give the blades a bit more room?

    Yes. Posted the same issue the other day to see what people thought of. Kind of wish it was my truck, then I could tear it down and look at things more closely to see what the issue is.

    I have 4 of my own electric trucks and have been running them hard for over a year in all the spots my buddy and I bash. I have yet to have a fan break on me. 2 traxxas and 2 castle. Only one has a motor fan (castle), but it's also been fine regardless of the abuse. He's been through 3 or 4 fans in a little over a month. $12 for a fan isn't bad... unless you have to buy 10 of them. lol

    Yep it's looking that way, I don't want to have to buy 10 just to make sure I'm not out of luck randomly breaking them here and there. Seems like another issue exclusive to Arrma. Probably due to their use of this fan that looks to be a cheap chinese ebay item.
