Radio Control (RC)

 

Aster Gauge 1 locomotives can be radio controlled.  Some models are designed to accommodate RC equipment.  In other cases, the receiving equipment and servos can be placed in a coach which is coupled directly behind the tender.  The regulator and reverse controls can be driven by means of extension rods and torque tubes.  Aster does not furnish RC equipment, which is available along with installation instructions at most hobby shops.   You can see examples at most small-scale live steam meets of Aster locomotives with radio controls.  

 

Locomotives should be "broken in" before RC operation is attempted.  While the operator is learning RC operational techniques, a heavy train should be pulled so that the locomotive will not "run away" and possibly derail,  The torque or force required to activate the regulator, blower and reverse controls must be low enough so that small servo motors are capable of driving them.  

 

The simplest installation consists of a single channel system and one servo, which drives either the regulator or the reverse control.  If the reverse control is selected as the driven system, the regulator must be manually opened with the speed of the locomotive being governed by the varying the valve cut-off.

 

A more sophisticated system, which provides a smoother operation, consists of two channels and servos driving both the regulator and the reserve control.  If the locomotive is not quipped with an automatic blower valve, the blower must be manually opened when the locomotive is stopped to prevent the fire from being extinguished.  

 

Locomotives with slip eccentric or slip crank valve gears cannot be reversed by radio control.  However, this is not a serious disadvantage.  A single channel servo driving the regulator provides satisfactory control and prevents derailment on curves.
