Bulldog was a design flaw. In bulldog 2, Mugen did not address the fundamental issues, such as plastic being too soft. With the 2 bulldogs, Mugen basically had to focus on making cars other than 1/10 buggies....
4WS steering radiu is small but in 4WS mode, it cannot run straight at all!! So most people lock up the rear. When the it is not 4WS, plus the semi-working differentials, almost like front and rear spools, the steering radius was BIG!!
