Hey Crew -

I'm trying to use a JETI JES 350 speed control with Old Kraft ( Ser 72 & 74). This speed control has a JR connector - wires are diff rent colors and pin locations differ also. Common colors are red/black which I take to be the power wires pos & neg (this when compared to Kraft servos).

Is the off color wire the signal wire? In this case it's either orange or brown. Correctly wired it would plug into the motor servo spot on the rcvr. Help.

Both these sets have been thoroughly checked out and tuned up and are on the 53 Mhz band.

Doable???

Yes I am doing it with a spectrum 6,

Red positive
Black negative
What's left is signal

Thanks for needed info. I subsequently have found out that the "new international system"(my words) are: red is always pos - darkest color whether black, brown or whatever is negative and the lightest color (yellow, orange, etc.) is the signal wire.

There seems to be no standard unless it's the above. At least, now I know.
