I am new here so I don't know is my thread in right section.
I have drone Q333-B and my little bro crashed it, so there is a 2 problems.
1- When push up left stick, at some point, he stop with spinning motors
2- When repeatedly turn up and down same stick he start lifting, but his one side is stronger then opposite, so I guess that is in damaged side so I need to replace it.
My question is about first problem, is it in maybe damaged receiver in drone or something else, I really don't know what it can be.
Thanks a lot to everyone. <3
