Just for heads up, while my nano was taken for its maiden flight around the pattern at Chambers County airport in Anahuac, Texas and upon landing it was noted that the Throttle Tensioner knob (black round knob on stick) was missing, looked all around the inside of nano and nothing, so Tensioner must have vibrated loose while in flight , fortunatelly it did go throught the prop. I remembered I had another one that I had recieved from Jeffrey so it was installed on nano and we put a little dabe of red silicon at the end of screw so that knob will stop at silicon and not come off and possible go into prop..
