Yes it could be possible. but if you getting a new system already. Some esc require if you change a radio setting like you have to re calibration the esc which don't make sense. I would look at the instruction one last time on the rtr one and talk to some one from you club for help just to make sure you are not missing anything. If you did all that all ready then I guess the change would be the go to next.
