I bought two of these last week along with a Turnigy multifunction programmer. My mistake, but why when you look at the ESC https://hobbyking.com/en_us/hobbywing-platinum-100a-v3-brushless-esc-w-10a-bec.html?gclid=EAIaIQobChMIntPsjqzz2AIVrp3tCh1rWAAaEAAYASAAEgJjQPD_BwE&gclsrc=aw.ds does it show the Turnigy programmer as one of the essential items for the ESC? It caught me out and will probably catch others out too. It should show the Hobbywing programmer https://hobbyking.com/en_us/hobbywing-multifunction-lcd-program-box.html?___store=en_us which looks identical but isn't.
