spastic tail
About halfway into a flight, five minutes or so, the tail started randomly swingng wildly 45 degrees one way or the other. Then, once it did a full 180 and I set it down (ok... I crashed). Changing out the battery (Nimh) took care of the problem, but I only got about 5 minutes out of the second pack.

Is this a low-voltage problem, a glitch or maybe a failing tail motor? I searched but could not find this.

Thanks.

I have had that same problem from time to time, there seems to be several things that can cause this.

1. either the main or the tail motor is going out and when the power drops a little they draw to much for the tail to hold steady power.

2. If your main blades are getting damaged, they can cause overheating in the motors in about 5 minutes due to excessive drag making the motors work to hard. Overheating then causes to much current to be drawn for the 4 -1 to hold a steady heading.

3. The timing could be coincidental and you could just have a glitch in your antanae or receiver.

Good luck
