[NSRCA-discussion] Noxville Contest??

[Fred Huber]

\Run a little test with those ESC's....

with the "arming switch" off, plug an RX battery to the ESC.  Then try to start the motor with the TX.

Alternately, you can hook a voltmeter to the + and - leads of the plug for the RX, then turn the switch on and off a couple of times wathing the meter.

If those switches do like most on ESC's with BEC, all they are doing is turning BEC power to the RX off.  While this SHOULD keep the motor from turning when you are using the BEC to power the RX, its not as sure as something you do to break the circuit to the motor battery. (such as the modified Deans plug or a removable fuse....   I like the Deans plug idea as its almost the same thing as the automotive blade fuse idea.)

  I have two ESCs with arming switches (Airboss and FMA). The switch is very small, with small guage wire. It does not remove battery power, it merely arms/disarms the ESC from operation. I really like that feature. I wish all ESCs had that feature.

    I personally witnessed an instance of electric starting unexpectedly at the Nats. Since I was only around Masters & FAI I believe it safe to dismiss the problem as lack of experience.

    I feel it essential to implement some kind of safety device to prevent this from occurring. I would prefer a mechanical lockout of some sort or at least an arming plug.

    The airplane was being carried back to the pits when the failure occurred. The handler was on top of the problem but it could have happened after the plane was parked.

    It is a disaster waiting to happen.

      Another reason to go electric.

        I have an $8000 left thumb. They installed a couple of options while they were rebuilding. It warns of weather changes and also serves as an alarm clock (sometimes).

        I recommended that a student headed for a pro basket ball career give up RC until the career was behind him.

          About two years ago I got my finger in one It cut the right index finger off at the first joint. Wrapped the finger in a towel went to the hospital with the severed finger, three month's and $6000.00 later it was almost as good as new except it is still numb on the end. APC's show no mercy.
