MMP Problem

[Arct1k]

Its well documented that the MMP bec is actually only good for 2amps (Well Briang said so its gosple) and that you may need to use an external BEC.

Thx

True but even when I am not powering the servo, ie ESC plugged into the receiver with led's only, they still won't light up. I know my LED's and the fan don't draw 2 amps.

lol, "gospel" eh? Not sure about "gospel", it was just measurements from the few MMPros I happen to have.

That doesn't make any sense at all. Unless you have the LEDs wired in such a way that they consume more than ~2A, they should light up no problem. I assume you have the proper current limiting resistor for those LEDs? Because if you don't, they can draw a lot of current (and usually blow in the process).

Make sure the LEDs use the proper resistor(s), make sure you have the LED ansodes going to + and the cathodes going to -, make sure the servo plug is inserted the proper way in the receiver, and then measure the voltage (AC too to make sure you aren't getting a ton of ripple, which means a bad BEC) at the LEDs.

I tried the LED's off the VXL esc in the Slash by plugging them into the 3rd channel as I do with the SCRT10

No problems there, they work fine.

Only does it on this ESC.
