Hinckley Radio Control Car Club

Just like the subject says which is best to use? I've got both. I raced my B4 and B44 this weekend and both have notchy diffs. The b4 diff is only a little bit but my B44 makes loud clicking noises.

I think I will leave the B4 diff alone as it performed well at the races, well, so did the B44, but the clicking was embarrasing.

Thanks
