[MidKnight]

For an 8s speed runner, which of the following 2 MKS would be the best choice for the limitless

HBL575
HBL599

Not familiar with either but I honestly just run a stock Spektrum s652 in my Limitless. Haven't had any issues at all and been up to 138mph with it again no issue. Don't think you need much of a servo for 10% steering rate and no turning during the pass just for turning around basically.

Hi guys. I got the MKS HBL 550 for my Limitless build. It didn't come with the servo horn mounting screw, and it looks like a ridiculous small thread size. Do you know which size/length of screw is needed. Thanks!
