I have a new to me railking rs1 that has a ps2 3vlt board. I have cleaned the wheels and pickup rollers. replaced all the traction tires and oiled sparingly were nessesary.
running the engine with dcs the engine runs smooth at 2 smph with the excel rate set at 2. the engine maintains its set speed given on straight sections of track fine.
when the engine goes into a curve it speeds up slightly. then when it goes back to a straight section of track it returns to the set speed given.
what would cause this issue? could it be a gearing or lubrication issue? or is the tack sensor or ps2 3vlt board having issues?
if this is a board software issue. would a ps3 upgrade solve this issue?
what should I do first to solve this? I love this engine and I really wanted it, but the slow speed control really bugs me.
