Thanks
What did you ground Pin1 (IC5 0r IC6) to? :p

When you remove IC5 and IC6, you can see a big fat trace underneath them that was connected to pin1 on both chips, and is grounded.

If you attach to either pin 1 trace, it will ground the circuit. Alternatively, you could connect the wire to where the - battery wire attaches to the board.

Just finished wiring the grounds of the fet's to the battery. I cannot really tell if it made a differences.

i'm sure you'll see a difference once you move up to high current draw motors....the difference being the fet upgrade can handle it while the stock fets simply melt

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. :cool:

haha sorry but i dont get the diagram.. which prongs attach to the esc?.... thanks

Just ignore where all the lines cross unless there is a dot at the junction.

Basically, it works like this:

Connect the sources of both IRF4905s together, and then connect them to the positive (+) battery terminal.

Connect the sources of both IRL3705Ns together, and then connect them to the negative (-) battery terminal.

Connect the drains of one IRF4905 and one IRL3705 together, then connect that to the positive motor lead.

Connect the drains of the other IRF4905 and IRL3705 together, then connect that to the negative motor lead.

That leaves only the gate pins of each transistor unconnected. Connect the gates to the pins on the main board as indicated.

hmmm...maybe i connected something wrong. Sorry about that.

update: Is working :)

If I was to wire the new FETs as described in the last schematic, could the servo and everything else on the original board opperate on just two AAA?? Leaving the other battery compartment for say a 9V wired to the FETs?

ok neuro..
so if i wire it like in your diagram, do the positive and negative wires from the batterys still have to connect to the 2 gold disks that have (3) and (2) next to them on the pcb?

same thing doing a direct connect to the motor wires.. do the motor negative and positive wires have to be connected to the golddisks with (6) and (7) next to them on the pcb still? 0r can the positive and negative motor wires just hookup directly to the fets? thanks

according to neuro's latest diagram, the battery will connect to the pins on teh FETs (but don't remove the existing battery wires from the pcb....pcb still needs juice :D ) and the motor now attaches directly to the FETs

ok it still doesnt make an sense to me..

just follow the diagram a few posts up. where he labels + or - battery, solder a wire at those pins and connect the other ends to the battery terminals. where he labels + or - motor, wire that up to the motor. wherever he labels IC6 Pin 4 or whatever, just solder a wire there then find where pin 4 of IC6 is on the pcb

neuro can you post a pic of the pcb with your mosfets added
?

yoohoo?
