Repair SBEC charger on a Petrol RC Helicopter

Here we demonstrate that sometimes an oscilloscope is required to find a problem and show that a cheap oscilloscope will often be enough. We look at what is wrong and how I am using the BEC to charge a LiFe battery and power servos on an petrol RC helicopter using a BLDC motor as a genorator and 3 phase rectifier to power the BEC.
