so there should only be 4 wires going to the external board from where the stock motor fets used to be?

another question, neuro, can i keep the stock fets on, and then just build a external fet mod and solder the correct wires to the correect stock fet pinS?

You can keep them on if you want. But there is the possibility of still buring up the stock fets because current still goes thru them. It's a 50/50 chance it will burn with it or not. Besides it is easier to solder with it off, and remove the aluminum heat sink at the bottom of the car to remove unwanted weight but keep the paper piece to keep most dirt off of the electronics inside.
My Two cents
Feel free to fill the bucket

Hopefully this should clear things up. Note connecting directly to the batteries is ok but don't forget to connect to the main PCB.
Here is a revised img
If the picture doesn't show click the link here
I belive this is what Neuro said it should be. Note directly connecting the battery is ok but remember that the main PCB needs power also.
I fix the link.

I tried to make it easier for people to see where the connections go.

....did you check out codedat's pic? his pic pretty much explains everything......just solder each wire depicted in the pic to the places shown and you'll be ok. IC5 and IC6 are the fets on the bottom of the pcb...but all the info you really need can be found in the previous pages....just take sum of your free time and read through the whole thing and you should have more than enough info

Well, I now have the FET circuit hooked up this way. I thought it strange that LithiumXMod said that it didn't work, so I decided to try it myself. It actually does work, and now the only connections that need to go to the main board is the gates of all four MOSFETs. The rest of the connections are on the standalone PCB. Even a Plasma Dash wouldn't kill this setup now. Actually, even a Novak SPY can't handle the current that this setup can.

neurokinetik, TinyRC didn't give you 1/10th the reward you deserved when he made you a mod. THIS IS GREEEATT STUFF!!! I can't wait to get the FETs sooner or later....
Anyways, for some quick Q's: With your FET setup, the amperage limit is pretty high, from what I hear, so I'm thinking of getting the Team Orion Elite Stock 180 motor, and taking about 20-25 winds off the armature. It will have a bit of a high current draw, but I'm guessing the FETs you're using will be able to handle that.
I'm thinking, that with your FET setup, I could possibly run a 15 wind 180 motor, and perhaps that will kick some serious "asphalt" or something like that. I can hardly wait to save enough money to get this little beauty running.....Thanks again!
