   I just finished building this helicopter. I enjoyed this build. The counter rotating blades are quite unique. The whole transmission system is complex and causes you to slow down and check each gear. I usually run a test of the transmission before I install it in a model. Thank goodness I did. I reversed two gears. Overall a great unit for the price.
   The only issue I have is finding building instructions for the B model.
