[RESOLVED] radio lost connection after actuate the 5th motor

[zhanghaijason]

Hello,
I am using Crazyflie to do a project. I have a fifth motor used to actuate some mechanism on Crazyflie. It worked before, but now it loses connection everytime after I apply power to the motor driver, it lost connection.
The process is as follows:
1. fly cf to a specific location and stop there
2. actuate 5th motor.
3. Lost connection

if I directly actuate 5th motor without flying it, connection doesm't lost.

One month ago I did the above procedures many times, everthing was good. But now it starts to lose connection.

Hi!

Where is the 5th motor located? Is it near the antenna?

It is indeed a bit weird that it does not lose connection if you do not fly it and actuate the 5th engine. Are you sure it is not drawing too much current? Flying 4 motors is already takes up a lot of power for the tiny crazyflie

Hello,
I used another CF and it works well. I guess the receiver on the old CF was kind of broken. Thanks for your reply.
