[ARC5] [Milsurplus] Motor tuned ARR-2 ?

[Michael Hanz]

It's no different than the original switching scheme, Hue, which is step 
tuned.  The intent of the C-37/ARR-2A "electric tuning control adapter", 
which is synchronized with the compatible C-35/ARR-2A channel selection 
switch, was to eliminate the problems of long runs of flex tuning cable 
between the receiver and the control box.  That allowed more flexibility 
for where they could install the receiver. The motor drive adapter was 
cleverly made to be capable of installation on the original R-4A/ARR-2 
receiver.  Attached is the installation diagram for the whole shebang.
