help needed to repair toy quadcopter

[fm101]

hi,

I have a toy quadcopter(attached is picture) which stopped working after using it for around 15 times.

Both the quadcoptor and the flight controller turns on and both are producing sound in its initial state as it used to be before but the motors just don't rotate.

It feels like the rf signal is not received by the controller on the QC.

what can i do to find the fault and repair?



thanks

Unless the damage is obvious and visible you stand virtually zero chance of repairing it. It almost certainly contains custom programmed parts that are only available from the manufacturer (probably not the branded name) and you will not be able to get any technical information about it. If you want to proceed, start by tracing the schematic from the PCB, it will not be easy!

Is the shown flying battery fully charged? Is the controller battery high quality (not cheap) and new?

hi,

thanks all for sharing experiences...the battery on both controllers are good....using the same battery on the qc which came with it....

Check the part number and datasheet of those IC. If it has a link, related, or control transmit and received signals then just replace it. Hard to check those IC offline.
