I don't really think there is any more work involved in doing it this way than stacking 4562s or 7389s. This is equivalent to two stacks of 10 each (one for forward, one for reverse) of the 8 pin ICs. That's 160 solder connections to make. This method involves about 35 solder connections.
At this point, it would take a truly sick motor to kill these MOSFETs. I'm going to push the limits on it and wind something like a 10 turn motor to use with them. The current draw of the motor could cause some issues with the radio and steering servo, but I have a solution for that as well. I also plan to upgrade the battery wires and all power connections right up to the motor.
As far as adding more power, it could be done, but it is not required. I want to see what can be accomplished with just 4 cells at the moment, before moving on to bigger power sources.
