Hy guys... I am sure there was an explanation on this thread but been so long, I guess I better ask again... hehehe.... I upgraded my BCP with the aluminum swash... and lipos, It was flying ok until last sunday that i had a minor accident, lost flotation some how and came in to the ground, not hard but It got my blades chipped... I switched to the CF blades and now the Heli YO-YO's while hovering, I have it at about 5' and suddenly drops about 1.5'. Can someone please advice what to check for?, I am pretty new with helis so I would appreciate any help.... thanks and long live my heli.. hehehehe
