    Onderstaande kwam ik tegen een idee wel een goede uitleg… Zal het binnenkort een keer vertalen.

    ============================================÷=

    Although not always true, a rule of thumb is:
    Hot motor, cool controller, cool batteries = undergeared
    Cool motor, hot controller, hot batteries = overgeared
    Warm motor, warm controller, warm batteries = happy components

    Hot, warm, and cool vary as well, so here’s another general rule:
    Hot for a motor = generally over 160F (71C)
    Hot for a controller = generally over 150F (66C)(or “thermal” range for the controller)
    Hot for batteries = generally over 150F (66C) for nimh, 130F (54C) for lipo
    Warm for a motor = generally 100F (38C) through 150F (66C)
    Warm for a controller = generally 100F (38C) through 130F (54C)
    Warm for batteries = generally 100F (38C) through 130F (54C) for nimh, ambient temp through 120F (49C) for lipo
    Cool for all components = generally ambient temp and up to 10 degrees F (5.6C) more

    The reasons the above are not always true are numerous, but may include:
    Sticky drivetrain – will put un-necessary strain on electronics whether geared correctly or not.
    Poor quality batteries – batteries will heat up regardless of gearing.
    Wrong motor for the application – will put un-necessary strain on electronics whether geared correctly or not.
    Wrong controller for the application – will put un-necessary strain on electronics whether geared correctly or not.

    The list goes on, but this can give you an idea of things to watch for.

    Edited to add the following:
    Please note that this information applies to the sensorless brushless systems typically found here at RC-Monster.com (BK Warrior/Micro controllers, MGM controllers, BK motors, Lehner motors, Feigao motors). These rules do not apply to brushed systems or other brushless systems, at least not in the same ways.
