The softer B4.1 arms have one built-in ball end for the swaybar, the B44.1 arms are a little firmer and have two of the ball ends. Then you have the Carbon arms which are the firmest.
Order from softest to firmest.
B4.1
B44.1
carbon rear arms
Most run the B44.1 rear arms on the B4.1 because the B4.1 arms tend to be too soft and noodly. This is the conclusion after reading many discussions on this matter. Chris from AE has listed the same order as above. Others will tend to argue this matter.

Actually, I was confused by this recently. I bought a stack of spare buggy arms and some more 4wd buggy arms, and when they came in I thought they screwed up and sent me just B44 rear arms. However, in my brand new B4.1 FT kit (and marked B4 on the tags on the spare rear arms), all the rear arms had two balls. Interestingly, they were not inserted in the bag the same way. One had the bend in the arm closer to the tag and the other had it down, and they were consistently that way. I assume this indicates which is which, but there's nothing about the arms themselves that provides any indication of how they differ. I'd just stock one type if I knew the B44 arms were equal or better than the B4 rear arms. Just one less separate line item to stock...

Others have told me that the B44 are the softest, then the B4, then the carbon (firmest). Doesn't mean that's correct, but it would make sense for various reasons.

softest to firmest.
B4.1
B44.1
B4 (older)
carbon.
it's all very confusing and AE needs to standardize on the a-arms.

What 17.5 motor would you all recommend for a FT b4.1 8mm running in a blinky class?
I run at a medium size indoor clay track. My Tekin 17.5 isn't fast enough to keep up with the fast guys at my track.
I make the A-main every time but never finish higher than 5th. Those guys are always pulling away from me, especially in the tight sections, and they won't share their secrets!
in case it matters, i have a very smooth driving style. Running 72/33.
FYI: I saw that one of them was running a revtech on Sunday but I have no idea about the rest.
Thoughts, suggestions?

Does anyone have any issues with the steering bellcrank screws tightening up by themselves and binding up the steering? I have this issue on one of my SC10s. I don't have the issue with my B4.1 or my other SC10. Quite strange.... I had to take the front end apart twice in a week to loosen it up.

I'll gear up to 35 if I can wedge it in there but I think I'm going to give up too much low end with my Tekin if I do. Hence the motor questions.

X12, Boss 17.5, or RevTech. All torque monsters.

I don't think you have much to worry about on the B4.1. Give it a shot, it won't hurt.
