I've just purchased my WLToys A959-B. I'm going to wait until I get my A959-B to purchase an upgraded Motor because I've heard and seen YouTube videos of the brushed 540 Motor and it's pretty fast. Does anyone recommend me going brushless and if I did can I just buy any type of brushless to install in my RC? How do I find the right brushless Motor by size, type, power, etc? And do I have to change out wiring and other items in the RC? I don't know how to find all the answers to these questions so that's why I'm asking in here. Any advice and/or answers would be much appreciated.
