XRB droopy blades no different

In an attempt to increase the agility i applied tape to the underside of the blades while bending them down. This induced a droop of about 8mm static. In the air they coned up less but the flight chargecteristics remained much as they were.

Oh well it didnt cost me anything to find out.

I find that under continued use, the blades "soften" in the area ajacent to the black hard plastic. This increases the "coning" and eventually causes the blades to go out of tracking. To prevent this, I inserted a very thin straight pin CAREFULLY thru the blade lengthwise from the attachment end toward the tip. This gives the blade a "spine" past the point where softening occurs without adding significant weight. My blades still cone but do not get too far out of line

I have the tethered XRB. FWIW, I discovered the hard way that the blade area at the root grip can fatigue. I did not pay close attention to this wear and my only crash to date was a spectactular in-flight display of carnage when a blade was thrown like a dart. I now use a strip of kapton tape at the root ends to extend the life of the blades.
