    HO Challenger jumoing tracks on 36" radius

    Hi Everyone My MTH Challenger's 2nd driver (truck) is not staying on tracks when entering a 36" radius curve. The front wheel-set of that driver starts articulating but then lifts off the track. Does anyone have a solution or tips to troubleshoot for this situation? Blessings
