hiii frnds,
     after a small crash my motor is bubbling (forward backward) with beep beep, i reconnect all things then its working for some time and again same thing. plz help me whether it is a problem of motor, esc or tx rx. thnx

i wanna add one thing that when i reconnect, its working up to certain throttle position but just before full speed it stops working and my plane falls on groung

i suggest you check the bullet connectors on the ESC and motor! they might be loose so you will need to re solder it!

Thnx naveed
    You are right there was same problem as u told. As I remove the sleeves of connectors. I found loose solder.
Now it's ok thnx again

the problem was in Radio.
i connected the Radio to the Pc which showed me that few channels are not working.
