I just bought a mini Grave Digger for my son for Christmas. When I tested it out I noticed that it accelerates slowly and then goes full speed. It feels like the speed controller is limiting the current when starting from a stop. Is this normal? It doesn't wheelie from a stand still like the Grave Diggers that I've seen on youtube. I broke in the motor by just driving it around at half throttle for the first pack. I didn't think I would have a problem with the motor since my Slash motor is still going strong after a year and it wasn't broken in at all.
Is it used? Cogging is assoc with brushless motors but it doesn't sound like yours is stutter starting. Could be a loose wire.
Modded to the Max
Drive it like its Hot
It's brand new. It doesn't cog. It feels like it's getting 50% power for the first few feet.
The LED on the ESC is red so the low voltage detection is off.
If he had to break in the motor I assume that it is brushed therefore will not cog.
It could be a faulty ESC...
I would start by resetting everything to factory settings, then call Traxxas if the problem persists. They are very good at taking care of their customers!
Whatever it is I just typed... could be wrong.
Thanks for your reply.
I'm not planning on driving it again until I give it to him for Christmas. I'll see what happens.
