I have heard of people stripping off the heat shrink and coating them with thinned epoxy. The thing you have to be very careful with is the metal weight in the tip. If not secured, think about it, a shard of 1/8th" X 2" metal crossing the room at 1800+ rpm. I stripped a set a while back, but never put them on. I've been flying my second set for two months so I haven't needed them. I have a brand new set of syms and haven't used them. When I get brave enough to 3D I'll put them on. I probably never will use the stripped ones.
I cracked one of my blades once, then flew it anyways in my basement, that weight flew out and hit my furnace and left a dent! I'm just glad it didn't hit me! I wasn't high off the ground, but was too close to a bucket, and coincidentally hit the same blade that lost the weight and shattered it to it's entirety. We're still finding shards of it, and that was 2 months ago.
NewBladePilot, in my experience it will actually fly much more stable at a higher head speed vs. pitch. The trade-off is that you have to give it alot more throttle to keep it airborne and go through a battery almost as faster than you would beleive. I would just start with throttle trim at zero.
