RE: Blade MSR Main Rotor Grips - Washers and O-Rings
I just bought my mSR after getting pretty good with the mCX and the first day Ipopped the back of the tail motor. I managed to do some neck breaking surgery and fix it. I had unplugged the tail motor and was working on it. upon fixing it it flew fine but after a couple batteries it started to fly like you are discribing Idid a bit of looking and noticed that the plug for the tail motor had come unplugged but was still making minimal contact still. Long story short Iplugged it back in and it worked fine. Try to see if your tail motor plug has come undone.
