Hello mleemor60, thank you for the response.
To answer the questions in order
:
1.)No - MR02 has stock 3010's (4pcs), AWD has SP8M4's (6pcs). The AWD Fet job is pristine and from my experience should not cause the signal loss I'm having;
2.)No - No carbon-fiber-touching going on
;
3.)Yes, I've tried the exact same motor in both cars;
4.)The motor is a Speedy05, brushes are fresh & broken-in;
5.)Armature is clean;
6.)No arcing;
7.)No questionable connections in the AWD car, including antenna;
8.)PCB is hard-wired to battery terminals, 18ga hi-strand-count wire
.
The funny thing is this AD-AWD has worse (much worse) reception than my Old AM-AWD PCB with a 2x3 PN AN0113 Fet job 2x3 (6pcs)
. I am considering removing the AD-PCB and swapping-in my old AM-AWD PCB.
Since exhausting just about every simple reason I can think of for the discrepancy between the AD-MR02 and AD-AWD's performance is why I'm leaning towards the problem being something wrong with the AD-board itself.
