this to me, someone board swapped an MR-02 to convert to Sanwa, still using 4 AAA and Kyosho servo.
The question at this point is, does board swapping while maintaining the Kyosho servo and 4 AAA power remain a relative 'stock' car? Given Kyosho's multitude of board options available in current availability, it would seem unless the Sanwa board through put heaps more power to the motor, it remains true to a stock car in the sense that it maintains stock steering, stock power capacity and really only changes the PCB. I would argue that it should also keep the power switch...
Do board swaps like this and similar PN PCB replacements negate the notion of remaining 'stock' just because it isn't a Kyosho board? I'm inclined to debate that Kyosho no longer maintains a hold on what it means to be stock given the shear volume of development of board systems for this scale and well, the shear volume of board systems Kyosho itself has put out.
