yup. that was me asking the question. it's good news indeed - no extra clash sensor!
also those boards are perfect for pairing with Corbin's driver because they have diodes on their battery input lines which squash their ma production and make them less good for driving LEDs , but they also have more accurate swing than the other boards due to the actual design of the motion sensor, and finally the timing of the extend and retract is most aligned to these boards.
so the result is the best MR sound around, no extra clash sensor, and a fully driven 1000ma "living" blade =)
