Time for another question to the been there/done that crowd:
I just ordered a Cobra 3520/14 for next year's PA ship. Specs say it has a max current draw of 46 amps. Will my Castel 50 esc be too small. Basically is there an overkill factor? Should I get a larger one? It is the full size with the heat sink, not the lite. Is there any benefit to using a larger one?
Thanks - Ken
Do you have an in line watt meter yet? If not, get one. It will tell you what you are actually drawing for amps.
Castle Edge Lite 50 has data logging. You can view a graph of your flight and see amp draw, voltage, temperature, rpm, and other cool stuff. You need the little dongle, last I knew a new ESC had a coupon for it.
A 50 amp ESC is rated to handle up to 50 amps, so 46 amps should be a walk in the park. However, just because that motor is rated at max current of 46 amps, that doesn’t mean you will be drawing 46 amps.
Did I mention you should get an in line watt meter?
