    Battery and gearing

    HI all,
    I bought my son a used exceed 1/10 truck. The Manuel says to use 7.2v 1800-3600 mAh ni-mh batery... when running the 1800 battery the esc gets a little warm towards the end of the charge.. When running the 3000 mAh battery the esc gets really warm within a few minutes and im afraid its going to burn up something.. So i my question is when going from a 1800 to a 3000 battery should the gearing be changed also? It has a 64tooth main gear and a 23t motor gear.. Im new to the truck stuff so any info would be great.

    RE: Battery and gearing

    Assuming the ESC is stock, you shouldn't have any issues with MAh changes, the only difference is longer run times. The gearing seems ok, but you could always cross reference the gearing with the RCUNIVERSE gear wizard calculator, it's very helpful. You could also try the touch method, when it's warm touch it and you should be able to hold your finger on it for at least 5 seconds if not more, if you can't, it's too hot.
