[ARC5] Wow...

[MARK DORNEY]

Control boxes?  You mean a pilots control box?  That’s easy. The mechanical, splined cables do the work, just like they do in an aircraft.  And if you have a dedicated radio operator, there is no need for them at all. The problem is any electronics, like the transmitters, that require 24 volts to power them.

It looks like the dynamotor for the rcvr is under the GP-7. Controls for tuning the rcvr and GP-7 remote on the dash. So it looks like the driver is the radio op.
