O.K. a few things. I am no expert but I know you should be using a 4 OHM with that 6 watt amp not 8 ohm. To use 8 ohm you need voltage booster. I have the feeling the strange noise you hear is because you don't have filters on those motors. If you look at HL stock motors you will see some small brown resistors on the motor terminals. Take them off and put them on your red motors and the sound should go away. also if you build little boxes around those speakers the sound will be much clearer and deeper than even this...

I am working on a sound set up for the Panther "A" that will have a DC to DC voltage booster. Going to test tomorrow night and will do some pics and video hopefully...

any idea what the resistance is of the small brown resistors . I thinks this may be the issue with the amp I have on Norma's KT

They have 104 written on them. Like I say all the time I am no expert when it comes to electronics. Maybe Jordan or Michael?

They are not resistors but ceramic capacitors. It is install to filter out potential electrical noise generated by the brush motors back thru the wires to the MFU. 

My understanding is that if the capacitor is use that way, the value can be quite small. If all else fails just solder one from an old motor and you should be okay.

Back to the problem of the noise, it doesn't not sound like a capacitor/filtering issue. Hach, could you try trimming down the throttle on the radio (i.e. reduce the max value on full throttle) and see if the noise goes away. It sounded like the noise Clark board makes when the full throttle/trim limit doesn't match.

I already adjust the trim on radio. it doesn't work. This 8 watt amplifier is newer. On Clark's web showing it must have voltage booster attach to amplifier.
I had asked Clark and got his answer: This was cause by motor, will be gone when votage booster is install

I will get a 2 Ampere voltage booster from different company in 3 weeks. I will try it until Clark's voltage booster arrive

Sounds a bit like a dog's breakfast just to get better sound. You need a daughter board to run the daughter board off the motherboard. a grand daughter board ?
