lol, the MMM V1 flamed to a crisp. The odd thing about that is it was running great with super temps of ~110*F (I checked periodically). I stopped for 10 seconds while talking with glassdoctor then it just started smoking and then flamed. The ESC is completely destroyed. It desoldered the power wires and crisped the BEC wire. The BEC still works fine once I replaced the wire. I sent that ESC in for a V3 replacement (but I did say I would take several bad V1's instead - but marked to void future warranty claims. They said they will send a V3. I tried. ).

The HV110 popped a capacitor spewing cap guts onto my GTP windshield. Must have been a weak one because the other 5 look perfect (no puffing). Sent that in too.

This sucks though because until now, I've never blown an ESC. I'm getting a Quark 125B to replace the HV and will run it on 5s. The V3 will go back into the MBX5/Corr, but I still think the Quarks are smoother. If I could get another Quark 125B instead of a MMM, I would in a heartbeat.

And yeah, I don't mind using fans, where they make sense to do so. Dissipating 185w in a stationary setup requires a fan ... or an EXTREMELY large heatsink ... and I would like to have some work space on my 8' X 3' workbench.

I set a 3.5v/cell termination simply because of the 10A load. I anticipated more voltage "rebound" once the relatively high load was removed. I should use 3.6v/cell when doing this to Mike's new cells since they drop quite a bit less, but anything from 3.6v/cell to 3.8v/cell should be just fine.
