What are you guys using for a motor and ESC?

What are you guys using for a motor and ESC? Have you guys found a “perfect combo” yet?

Some, including myself is running this combo: http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=25138

Thank you! I have two more quick questions. First one, is the bottom plate printable but just in two pieces like you have on thingiverse? Like the one Benjamin Groves just posted but printed instead? Next question, are there any metal parts I should get like a drive shaft or another part or can everything stand up when you print it in poly carbonate and nylon? Thank you so much for your help and this AWESOME project!!!

Also this is the latest and greatest version of the car right, STL Files For OpenRC Truggy Rev B.3? As long as I print the .stl’s in that folder it should work for me right?
