Switching BEC protection

[eovnu87435ds]

depending on the size of it, I'm in. i've never had a BEC fail that way for me(i've had them short on themselves and cause smoke, but always cut power to the Rx) but with the price of a spektrum Rx, and a good servo for 1:8 scales you could be down a good 100+ bucks

Also, what about those with linear BECs, like the MMM?

i would like to invest in something like this. Had one blow years back and took out the servo....not the receiver strangely....

Brian, are you going to put this on a board with pwm leads coming off the ends for easy installation?

mabey this is a dumb question, buy why couldnt you use a bar resistor to bring the voltage from the lipo down to power the RX strait from the batt?? or am I compleatly stupid??

A resistor would only limit current not voltage. Think of it this way if you have a hose and it has a restrictor placed in line with it very little water will come out the end limiting flow (amps), but if you plug the end the pressure (voltage) will rise to the same as before the restriction. So when the current draw is near 0 the voltage will rise to a dangerous level and take out the RX and servo.

Brian this would be easy to add to the existing BEC on the board. Good idea using the fuse, I figured that the trace would be good enough.
