Its not too much a bother...but I just want to reassure myself that nothing is wrong. Heres the situation. I am running an IHC 2-10-2 steamer on nickel silver flextrack. (HO). I have a cheap RailPower transformer with some heavy gauge wire soldered to my 4x8 Oval. What concerns me is I have to turn the dial atl at least 1/4 of the way to full throttle before the engine even moves. However it really cooks after it gets moving...plenty of speed.I realize that its a bigger engine and may just need that extra power to get moving. Also, at times I will turn the dial and nothing will happen. I then have to power off the pack, turn down the trhrottle and start again...but its works fine then....this is a cheapo power pack..all my wheels and track are pretty clean. Any thoughts?
