Default Intermittent drop in power.

Anyone have any suggestions as to what would cause an intermittent drop in power. About 3 minutes into my main, the car would drop to half speed for 5 to 10 seconds, return to full speed for 10 seconds or so, drop off again and so on. I was runnin single cell 13.5 WGT. I'm running a Hobbywing 1S speedo and a D3.5 13.5. Neither the motor nor the speedo were overheated. Thanks in advance.

Problem with the speedo is my guess bud. Similar effects are seen with a faulty booster when running single cell lipo. Maybe just a cold solder joint on the board.

It could be that you are going below the low voltage cutoff setting of the speed control. If that is an adjustable setting on your Hobbywing speed control, you should confirm where it is set. Since it is happening 3 minutes into the race, it could be related to battery voltage (or even a bad battery).

Here is a link to the Hobbywing website (http://www.hobbywing.com/index.asp). You might also check to see if there is a firmware update that may address any issues with your model of speed control.
