    ezrun brushless motor .....HELP!!

    I have a ezrun brushless combo that I got new..hooked it up today to a tamtech frog...and the wires from the engine started to get really hot and smoke. Why? Running 1600 mah battery with traxxs connectors.
    Thanks for the help/

    .. maybe you have the power plugged into the trigger line or something (not real familiar in the naming) the two outside wires are swappable, however the center wire must be mated with the correct wire (the center wire) hopefully its still useable, but smoke is usually fatal.

    RE: ezrun brushless motor .....HELP!!

    pics of the setup would help rule out a wiring issue

    Chances are either the setup was too high KV for the RC. Smaller BL motors are usually EXTREMELY high in KV rating, and need to be geared very low.
    Or you wired it wrong. Almost want to doubt this one seeing I swore all the lower amperage EZ-runs are pre-wired.
    Or you got a bad setup. Lets face it bad ones do get through (and before anyone says SEE CHEAP I've heard of way more castle products bursting into flames than HW)
    With great speed comes greater repair bills.

    I just ran it for a few seconds and the motor wires got really hot and started to melt the casing off. So I shold use a lower gear? What size?

    Found the problem the screws that hold the motor on were a tad to long and were hitting the coil inside the motor. Put some spacers on the screws and good to go.
    thanks for all your help.

    That is my first guess as well. I don't think the gearing is to high if all it was couple of sec's.
