Sometimes it is not about making sense. Sometimes you just want to play and experiment. I have several x8s and I have modified all of them one way or another. I tried the brushless kit from the syma store and it was a flop as far as I am concerned. I do not have more power or longer flight time. It flies smooth and quiet with now load. With a camera on it, it is worthless. Won't gain altitude or hover and if the low voltage lights come on, I hope you are close to the ground. You will not have enough time to land it before the motors stop and your x8 falls from the sky. I did order the kit cberish is asking about. If it works I will be happy. I like flying and modifying the x8 because it offers a great platform to learn from. I have a bayang toys x21. I love flying that. But, it has a geofence allowing the quad to only fly 140 meters high. Sometimes I wan to fly higher. I'm sure the x16 is the same way.
