Hi Guys
I also installed the Lightwight Spool Cups.
It`s not easy to work on the bearing holders because the plastic clips must move freely. Are they to strong the drive train not spin free.
But now it works fine on my TRF 419X Version
Thank`s to RCRacer for the discription.
The Suspension Mount E on the inner side in Front doesn`t work because the belt is near on the chassis.
