I had some slop there before and that made is whisper quiet and smooth.

Ran 2 meetings with it and I like the traction. Only thing i noticed is that ran too loose you get a weird action when using lots of breaks.

we have one corner where we are tight on the inside of the apex and it's a 180 after a straight. so we all have to break hard and enter the corner much slower. I find the car will not turn in under breaking and kinda skids until is gets slow enough or I re apply power.

but the first time I'm running any type of spool
