I'm working on a bunch of new mods this month. For Trick or Treating, I hooked up a remote control keychain kill switch ($20 at allelectronics.com), so I could shut him off when other kids were near plus cool LED tail light arrays that fit inside the fake factory jeep tail lights.
I also have some 30K+ RPM ball bearing motors we are going to put the wood to.
