Misty Mk2 is an amended version of itís predecessor with a size small enough to fit in a 00 gauge cattle wagon. The circuit board measures just 29 mm x 50 mm. .
The circuit board connects via a switch to a pp3 battery. All supplied green sensing wires connect to the track via the wheel pickups from the motor assembly (details about this can be found here).
Some customers have successfully fitted all items in the same wagon others have put the battery in one wagon and the other items in another carriage.
Two adjusters on the circuit board allow volume to be altered and track sync. This allows you to correct the speed of the chuff against the actual speed of the loco.
