The only thing that will limit the speed of the titans is the evx. It run's faster in forward than reverse, so flipping the diff's is a bad idea.(you are right that brushed motor's do run slower in reverse due to the brake in, but the evx is slower) Flipping the tranny would be a 3rd option, but the real problem is the radio setting's. Reverse channel 2 and adjust the trim, then re-set the evx. It should hold the setting's, if not there is something wrong.
