The problem is not with the grade but the running gear of the VL Challenger. There have been numerous threads on the Forum of members reworking the mechanism for better operations.

If you could link any helpful info on the 2018 run of the VL Challenger that would be appreciated. I was thinking traction tires were the culprit but I’d be interested to know what others have done
maybe it’s because they left the two engines in sync 😜
