RedBullFixx - Thanks . I really do appreciate a professional opinion on this topic, but that's all that he's provided. There wasn't any reasoning behind it nor did he comment on the differences in handling.

But really...Why do 1/12th designers disregard achieving perfect rear pod balance? Doesn't make much sense now does it.

Maybe, I'm just speculating here... The distance of 3 mm he used in his test was probably too much of an offset. With this offset and the weight of the motor could of caused the screws to generate elastic characteristics (spring effect). This is all just speculation.
