    Overheating issue I think?

    When my son was using his Summit in the driveway last week it shut off after about 15 minutes, I just powered it up and it ran again for another couple minutes then shut down again. I powered it up it ran again for another couple minutes. Then shut off again, we just went in. I was explaining this to the guy at my local RC store and his thought was that it may have overheated. When we took the cover off the Summit it was blocked with snow. Has anyone had a similar experience. I figured if it was blocked with snow how can it be overheated, but LHS says it was smothered? Any thoughts?

    Check your Rx box for water.
    Could be overheated though...
    Whatever it is I just said... I could be wrong.

    I'm having heat problems too. Mainly with stock gearing and full trothle at low speeds (i.e. sand climbing or drifting).

    Undergearing, heatsink/fan and air intakes will help.

    *Note that ESC will flash red light when you have heat problems.

    Check the Rx box - no water

    Not that I remember, being new to Rc's I wasn't looking for any flashing lights. I seem to remember when it stopped that all lights were off.

    Hmmm.
    Hard to say exactly what happend...

    Keep an eye out for the ESC's lights. They will tell you what is going on.

    Someone suggested that it could overheat due to all the snow covering the motor and esc? Is that possible?

    I find my rc's run hot in the snow because the snow packs into the chassis adding weight and making it heavy. When I first starting running in the snow I thought I could gear up and not worry about heat. I was wrong I ended up gearing down (slower) to keep temps in check.

    Not only the weight, but snow is an excellent insulator... think of the Eskimos and Igloos.

    Any good in putting a heatsink on the motor and some type of fan on the ESC?

    I have a computer 6x6cm fan installed on roof and a heatsink for the motor. With this, your heat problems will dissapear. It's an inexpensive mod and 100% effective. My mini Sumit was having heat problems almost every day and now is always cool even with 3S. Also, undergearing is very effective.

    Good luck.

    My full size summit did this look in your manual and see if it has thermal shutdown protection. If so they most likely yes.

    You could be right there, it does have thermal shutdown protection. Which I didn't remember!
