Jerry, I have gone around and around directly with Ivano, first trying to convince him the ultimate was now useless for IR battle since I couldnt drive it around without running into things on the field and that I didnt want any inertia at all and then he agreed to modify the firmware some day. Its been two years of me bugging Ian and him.
I know several club members that tried out Utlimates as well and sent them back becuase they just had way too much lag for a 1/16 scale model.
