not tough enough apparently.....
after patiently waiting for a new MMM to be shipped to me, i ended up getting 2 packages. to my surprise, each one had a refurb. MMM in it. i did the honest thing and called castle, letting them know they had made a mistake in my favor and offered to send 1 back. the dude i spoke to on the phone said it was indeed a mistake and said he will ship me a pre-paid mailer to send back the extra esc.
one of the "new" escs has scuffs, scratches, etc. on the case and switch and smells like an esc that already let out the magic smoke. the other looked brand new and had that new electronic smell to it, so naturally, i chose the newer looking one to run. i soldered a fresh deans plug onto it and did one full run. it had weird, half-second "losses of signal," but i ran it until LVC. that was yesterday.
today, i plugged in the same battery, flipped the switch and nothing happened. i figured the switch was faulty, so i cut it off, stripped the wire ends, and twisted them together, like i did with my blur (hpi MMM) esc. still, there was no response. no beeps, no lights, no nothing. i tried to sync it to castle link and all it did was flash green and the castle link chip got a little warm after a minute of trying to sync it.
i must have pretty bad luck with speed controls.....this MMM is toast.
this was the setup it was run in:
CEN matrix BL converted buggy (~9lb fully loaded)
brand new, never used cc2200kv motor
4s lipo
geared for ~40mph
all i did was drive and drift it on the street with some old, bald tires. the esc, batteries and motor were all under 100F and nothing was stressed on this run. there were no crashes or jumps.
i soldered a new deans plug on the scuffed, smelly extra esc that was mistakenly sent to me and ran 2 full battery packs through it today (after the other one failed) and there wasn't any weird glitching like the other one and it worked fine with the exception of the fan. it sounds like the bushing is about dead. even if the fan does die, it should be fine, because during those 2 runs, it only came on once briefly.
so i guess i will be sending a defective esc back in that pre-paid envolope.
