I'm just back from the track and for the first time today ( 7th time at the track since I drive a B44 ), I was able to enjoy my B44.2 without any issues. Why? I got rid of the Mamba Max Pro piece of cr*p and replaced it with a Tekin RS pro. I'm running a Tekin 5.5

You can see in this thread why I do not recommend the MMP:

And for the Savox servo... If you have it, use it...
