I'm in my R2 build at the stage where I will work on the electronics man Kyber is so tempting but $250 for the body board, plus a controller with a screen, is another $250 ... price is the only thing holding me back to from going with it and not ShadowMD
I don’t sell Kyber. I stared my droid journey with SHADOW-MD. It was/is awesome! However, Bluetooth, although inexpensive has a fundamental flaw. It cannot survive today’s Bluetooth saturated conventions. My first taste of this was with my, at the time, Bluetooth R5. I was at a convention with 20,000 people crammed into a convention hall and he was uncontrollable. Just too many folks with phones.This saturated and jammed the Bluetooth frequencies. Modern Radio control transmitters are effectively immune to this problem because they use frequency hopping Yes, the is a cost to this tech and the controllers are big and visible to the audience(although if you are clever it is possible to mitigate this by standing behind the observer or use other ‘magician’ techniques. You can certainly start with Bluetooth. However, in the long run, if you find that you are passionate about this hobby/profession, RC is really the best tech.
