Yes the serpent ones are AAA and these ones I am using are AA prob. a little bit heavier but I think the car needs the extra weight to be legal from what I read somewhere .I just ordered a bunch of stuff from tower hobbies but they dont have aot of the stuff that I will really need like upper lower arms and steering blocks.
I am looking for a good place to buy tires for it but cant find any. where do you guys buy the tires at I will be using the mrx3 tires for it.
