When you make the effort to deal with rcma in store which I have many times,from my first bundle purchase of an apprentice trainer,dx6 transmitter and lipo batteries right through to today, 7 years later to the purchase of a Dualsky GA 4000.7 motor and a 160amp esc for my extreme flight 74inch edge 540 3D aeroplane,then I hope that you will come to the same conclusion that between Mick, Karen, Adam and Matt who man the phones and the counters at RCMA,all of your RC challenges,merchandise and questions are professionally met with the combined years of hands on experience and customer service you should expect.
