Cougar KF belt eater

[frenno]

Hi, My first post...

I've been away from r/c racing for 25 years I just got back into it and as we race indoors on carpet I went for the Cougar KF, last car I raced was a Cougar 2 team!

Ive just about got my head around, brushless, lipo's and the new esc's slipper clutches etc

But I'm having real issues with the belt on my KF, I've been through 4 already and I've only raced it 5-6 times! I've been in contact with Schumacher who think I'm not running the belt tension high enough, but I think there is an issue with my kit, it seems like the belt isn't running straight I keep finding the pulley fence is coming off one side allowing the belt to chew itself on the slide of the pulley...

Has anyone heard of similar issues with KF owners?
