Well, I am into radio controlled cars. Mostly 1/5 scale petrol cars (they have 26cc two stroke engines and do about 45mph), but I also like 1/10 scale radio controlled cars (4wd electric rock crawlers). Currently busy rebuilding / modifying one of my 1/5 scale cars (Hpi Baja 5SC).
This is the 1/10 scale rock crawler which is next on the list to be upgraded. Just waiting for the parts.
