I came in a slightly complicated situation when I had to fix an old RC car
recently. The old setup consists of old Sanwa servos and receiver. One servo
(and now also the other) broke and I replaced it with a new Futaba. To get
this to work in the system I had to switch the positive and negative cables.
I realized this after some trial and error, and I guess I might have
affected something in the receiver during this.
Now the receiver mirrors the directions of the servo's turnings. When I pull
the steering stick to the left the wheels turn right, and when I press the
power stick forward the car backs and vice versa! Do you know how to change
the directions or "polarity" of the receiver?
Another quesition; do you know if a new receiver will work with my old
remote control and the crystal?
