hello all, i got a little problem with a gp7 proto 2k i noticed that it often derails in the rear truck too easily while running at lower speeds, and on my test track any ideas, there is no problem with the trackwork the coupler pocket according to nmra standard gauge is perfect. also the wheels ar in gauge also to nrma gauge any ideas?
Might want to check these things:
-
It’s the right truck (protos have a front and rear) ?
-
Truck is installed correctly?
-
Wires aren’t too tight to allow the truck to pivot?
-
Are the gears in them good?
