Man...I dunno. Everyone is out of the stuff for Blade CP (just because I want/need it). If you can get it all in one spot, great, otherwise....a small fortune in shipping charges (HOMEY DON"T PLAY THAT). If you're noticing a more agressive slippage...change the motor out and see what happens. They fail gradually (loose power). Total failure at 15-30ft in the air is a bad time to say "Wished I'd changed that motor". Motors are cheaper than replacing a CNC head that's been twisted into a pretzel!!!
