Two ESCs Fail I’ve had two ESCs fail in one day, one in a zero-throttle fast descent and one while bench testing with no props and running off a 5A current-limited bench power supply. Both play the little tune through the motor when powered on but ignore PPM input and […]
The Fault No transmission – pretty simple really. Testing and Repair Turning it on and all seemed OK. The small radio scanner showed that there was no signal transmitted; at least not in the 40MHz band. Maybe the crystal or part of the transmitter circuit had failed. Next, open it […]
A Typical RC S-BEC I bought a couple of these S-BECs with the intention of installing one in a FPV wing. Before doing this I needed to know what it was capable of. This module is from Hobbyking and is rated to 26 Volts input and 5 Amps continuous output, […]

Channel 3 (throttle) from the receiver goes directly to the ESC. There is no connection to the BATT terminals on the end. Power is applied via the leads from the receiver to […]

What Happened Flying late one afternoon I was spotting and the Hex with a Naza controller with GPS was being flown FPV about 200 meters away at about 70-80 meters altitude over a long-grass field. It stopped responding to RC and was switched to RTH mode (return to home). It […]
I’ve been having a look at this board. Being new to Multiwii and the lack of information and incomplete documentation makes it a real challenge. At first glance it looks very nice for the low price. Then after some hours you start to find the hidden catches; like, it needs […]
