I find that there is something incredibly satisfying about getting a 2WD round well...there nothing anything like flying round a long sweeper with the front wheels on full lock into the bend and the buggy follows the front wheels in a gradual flowing way. 4WD is very 'Point and Shoot'. I still run 4WD and feel that just as much skill is needed, just skill in a different style of driving. 2WD is just so much more reliant on set-up and the drivers ability to control the buggy both in the air and during cornering. The racing line is far narrower with 2WD...Less margine for error for us mortals
End of the day both classes need skill and nerves of steel, and are equally fun when driven with like minded racers...4WD can be a bit of a demolition derby at some club meetings lol especially these days with motors running so quick...have fun and best of all never take it too seriously
