Yes the power module is just a bec but not all bec are created equal. For the tradition airplanes the bec (battery eliminate circuit) were created so you did not need to add a second battery to power simple devices on your aircraft. But flight controller need much cleaner power. The voltage bouncing up and down does not bother LED's but it does bother the flight controller, for instance. So it depends on the quality of the bec on the 4in1. Most people don't run flight controllers off a ESC-bec because they don't trust them. But that does not mean they are all bad. But unless you have an Oscilliscope to look and the waveform it is hard to know if the bec of an ESC is good or not. Since that situation will not likely happen and as you say in a failure situation it is probably better to have some power than none, and your convenience.... (责任编辑：) |
