Sorry, the b5 reliable ?? where I live,all the rc shops carry and sell mostly associated parts, Why ? I know they are very accessible from anywhere in the u.s, o.k every time I go to the track I always see the associated brands breaking, B5 B44.3 SC10 ect. I am not saying there is a bullet proof car out there, there is not....But as a business owner for a rc store I would sell associated..
