Okay, here's what Gadget looks like on the inside. I pried the board away from the battery box enough to determine that it's a one-sider and there's nothing to see there and no reason to tear out the battery-contact posts.

Interesting that right next to the "LAUNCH" and "MOVE" button connection points are 4 contacts labeled "SPEED", as though they were originally designing it to have controls to inc/dec the speed remotely. But I shorted those leads while the learning remote was "listening" and it didn't see anything, so they apparently didn't implement the extra signals those buttons would've transmitted.
