EVO Mosfet mod
Posted: Wed Oct 19, 2005 12:30 am
Well I finally installed the new, upgraded EVO mosfets into my EVO chassis. These mosfets are the ones I found to be more efficient than the stock mosfets.
The installation was quite easy, you don't even need to remove the PCB from the chassis, I just removed the top plate and started hacking, lol....
Yes, the stock EVO mosfets are pretty strong, they will handle a lot of hot motors out there. But ultimately, push them enough and they WILL blow. See mine below, I fried them in no time, lol....

Another key ting to note is that the upgraded mosfets are more efficient. This leads to increased current flow and therefore more torque in the motor. More torque = slight increase in speed.
So I got my EVO MOSFET Upgrade pack from ausmicro.com, you can get them here:

So here's the new 2x2 stack of improved mosfets.

Not a lot to look at I know, but they sure do pack a punch! Notice how on this mosfet stack(side facing the motor terminals) that the 4 legs aren't all soldered together as in the gen1 mosfet stack was. This is due to the mosfets being different in the EVO so you have to be a bit more aware of what you're doing.
The 2x2 stack is a little bit too high to fit the cover on it without a little bit of modding. It's not too bad though. See below.

From the angle shown below you can see that you could possibly fit another level of mosfets onto the stack and get a 3x2 arrangement. The beauty here is that the 3rd mosfet will most likely make contact with the motor terminal connnectors and this will in turn help the mosfets keep their cool.

It's shit's me that I trashed so early, i had like for like 20 seconds on the pavement when it went boof! fuck!
