What was found
GRIP PAD COMES WITH ADHESIVE ON IT. TO APPLY, REMOVE PROTECTIVE TAPE, ROUGH UP PREAPPLIED ADHESIVE WITH SANDPAPER, THEN MIX UP ANOTHER ADHESIVE AND INSTALL GRIP PAD TO BLADE. PROBLEM IS THAT THE PREAPPLIED ADHESIVE LAYER IS TOO THICK, AFTER INSTALLATION OF GRIP PADS TO BLADE, THE BLADE CANNOT BE INSTALLED INTO ROTOR HEAD.
