Hello everyone ...
After changing engines (Avroto) on a 550 naza I can not connection the WKM with computers,
are the new motor works normally (I did flight) but I can not connection ...i did uninstall and install the program and the drivers ...many times reboot ...but nothing....i put klik and stop the program in skip ....and next put skip and flushing red mc connect ...
Before the change everything was ok ... I had no problem.
Can think about something other than what he did ..; or something that i do ...?
Thank you

Antonis

Today after a flight with naza Back at home I tried again to connect to the computer with naza and WKM .After 2 to 3 times connect and disconnect he made the connection itself (without touching anything) began to whistle simultaneously all the motors strong beep...!!!!
I removed the battery again tried but nothing .. all MOTOR Once you connect the battery then do beep !!!!
I looked at all the cables Motor and esc, look at all the connections again and again ... nothing ... the beep stops after you take all the Motors remove the battery ... and of course I can not connect...
Someone understands any of this;
what may have happened;
What may be all that?
