Hi John,

I've already got an AM tx and rx set-up, but am loathed to use it due
to the much increased risk of interference from the speed controllers,
motors, etc., which as you will know, is far more likely with an AM
system. Keep thinking!

Hello Paul,
I would try out your old AM set for sure. You never know
your luck. If the servo connections are compatible it will
only take a short time. What brand/model?

I agree with you that the AM set has an increased risk
of interference from your own motors but you said some
time ago that your robot works fine at your place but at
the venue with other competitors and their transmitters
around, the interference is bad for you with your present
Sanwa FM set.

Even if you do not fit the AM set to the robot, take the
working AM set in a box to the venue and see if the
servos misbehave in that electrical noisy environment.

Regards,
John Crighton.
