Xtreme Tough Main Blade (Yellow) - Blade 130X
I like those blades - they are responsive and extremely tough - never break.
I have them in red and yellow. My only complaint: Yellow blades are not yellow (labelled as yellow), but green. About the same green the packing of original Eflite spares has.
Dont label those at yellow - they do not fit to my 130x (red - yellow) in design ;)
