Well, I've been studying the SS board for a while, and I know that the SuperSlick CAN be FET modded. I've traced the motor wire traces to the FETs, and I'll show you which can be replaced.
Look in this pic, the transistors circled in red are the ones which can be replaced.
Same here, the trannies which can be replaced are circled here...
Now, I just need to trace their source pins back to the power source, so I can figure out where to place the N/P channel FETs,
the N channel FETs would be IRLML2502, P channel FETs IRLML6401.
One pair of FETs is for forward, the other pair is for reverse, once again I have to figure this out...
