Battery ???

[Westwind]

I think I might have a bad battery. The heli motor will start to pilate just before lift off after a couple minutes of running. I checked the battery voltage abd it's down to 11.2 volts. This dose not seanm right to me, anyone have an idea?

I'd get a lipo alarm and keep a check on the volts of each cell as you fly. The 1-8S costs £2 from China. It stops you over discharging your battery. I stop at 5 mins and set the alarm at 3.6V. In the cold lipos drop a lot more volts as their internal resistance goes up. Try them at 25 to 30 degrees C. A bit more info would help. Type of battery lipo? 3S? Cell Volts, Type of heli and normal flight time. 80% of capacity is another useful rule.

Now I got a new problem. charged up the battery to do some hover practice and to test it again but lost control of the heli after a bit. She hot hard a now I have a bent main rotor shaft. Did some trouble shooting and found the aileron pot on me dx6i (1 month old) is stuck on one side and jumps all over the place when viewed in the monitor if moved.
