When I plugged in the USB cable into the built in slot it never lit up or did anything. I tried blowing it out, etc. Nothing.  It worked just fine a few years ago and has only been ran twice since the last time I hooked it up to the link.
The Mamba Monster updated but somehow got switched to brushed mode and I didn't notice. Was at the track the other day and I put my batteries in and gave it some throttle and all I got was a blip and then nothing. Seemed like a locked rotor. I hadn't run it since the firmware update so I guessed it was a glitch and figured I'd look at it when I got home. I noticed the battery wires were a bit warm when I unplugged everything (they are NEVER warm), so that had me a bit concerned.
Finally plugged it in cause I was going to revert firmware to see if that would fix it and then I saw it in brushed mode.  Fixed that and it seemed to work fine on the bench (and I expect it will work just fine on the track again).
Also, I have another question regarding the Mamba Monster 2. Is it crucial/required to run the fan on it? The fan on my original MMM pretty much never turns on...and neither does the one on my MMP. Assuming I don't gear it to the moon, is it ok without the fan? Input appreciated.
Either way...love my Castle stuff. The only ESC's I own and will own in the future as far as I can see. (Though I noticed you guys just discontinued a bunch of your boat stuff...I was looking for a tiny boat to run in my pool...and think your new Hydra ICE was overkill - are you guys coming out with replacements anytime soon?) |
Thanks for the kind words BP!
The fan isn't critical - the ESC will shutdown if it overtemps.
However, you will limit the lifetime of the ESC if you thermal it all the time... high temps are hard on the input capacitors and MOSFETs, and they will not last as long.
If you can drive without a fan, and don't get thermal shutdown -- you are good.
Oh -- and your MMM that got put in brushed mode should be just fine...
Thanx!
