Matt,

Thanks for the info. That's a lot to quote, so I won't bother.

So you say it is worth upgrading the MC330CR. I will get sufficient FETS for doing one of those to see what happens (it is smaller than the Tazer 15T) plus enought to do a Tazer (and buy a Tazer).

What does a "4 volt gate" vs a "10 volt gate" mean?

Regarding 3 or 5 not making sense:

Duh! I hadn't even thought about traces on the top of the board! But I can't see those anyway until I take the FETs off.

However the 3 does make sense according to the ratings of the ESC: 200A forward (2 FET at 100A each) and 100A reverse (one FET). Could the other three be there for some other reason?

Thermal issues: Maybe I will see if I can add more heatsinking to the FETS on the MC330 when I redo it.

My question here is: How can I tell if it is OK to connect the various FETs on the MC330CR to the same heatsink? I obviously don't what to short the thing out after going to the trouble of upgrading it. Do I just check that tabs and if there is already no resistance (zero ohms) between and given pair, the it is OK?

Thanks, Mark

I've had nothing but good times with a Moped Bravo V16R reversible (the red one). Bought it from rcmart.com. US$30 or so before shipping.

The Rooster is tried and true performer. If it is in good shape, $40 is a good deal. it is a little big for a RC 10 though.
