I know this problem has been talked about earlier in a post but please let me empahsize it and my fix with my experience since I believe this can be interpreted as something else.
If your BR oscillates or begins to oscillate or swing back or forth as if it were tied on a string from the main mast, please check your small hinges at the blade hubs for slop. By slop I mean not a free moving teeter as was posted in a previous thread. The teeter should be loose and free movement, no restrictions as one did on my BR. When you touch the baldes they should teeter two to three times on their own before they stop. I had done a repair in that area and discovered a small drop of glue got into the hinge area so I loosened it with an xacto knife and white grease. I simply cut through the small gap between the hinge and hub and applied a small amount of grease. Keep moving the hinge to work the grease into the area of friction until the hinge teeters freely.
The stablility of the BR inflight returned to perfect, even better than new. At first I thought the oscillations were due to blade imbalance or even blade pitch, but this was not the case here. My oscillations would start out slowly at the begining of each flight and grow in amplitude to the point that the blades would actually touch with each other, and this is with the spacer MOD. What a difference now. Now I do not have to buy a new blade set, even tough I put one on order. Ha! Oh Well! Great satisfaction in finding a fix yourself!
I hope those of you who have this problem find my fix in your search and you get great results as I did, you won't be sorry!
