@Norton posted:Not a big deal. Just replace with an ERR Cruise M. The chuff in this engine uses a micro switch, not generated by the K-Line Cruise board so a simple board swap is all that is needed. That can be done anytime before or after you swap motors.

Few people know this but the K-line cruise board is capable of providing chuffs. My K-line Hudson now has 4 chuffs per rev. It is not synched with the smoke of course. I did the mod many years ago and have forgotten exactly how it is done sadly but it was not difficult.
