Hey I forgot one - haha.

At about age 14 or so I got an MRP Outrageous Drag Boat. That would be a 1/10th scale R/C, twin battery, electric engine. Thing was a screamer. Does that count?

In fact I still have it and my 8yr old has big plans to get it going again, although the color has faded pretty badly from a bright white to a dull yellowish haze. Years ago I half sank it after skimming off the top of a rock at full speed (~25mph), creating a 4" gash in the hull, and rolling it. It survived but hasn't been on the water for, (uh, how old am I again) a really long time...
