Futaba 3PM MX ?
 

i just got a new 3pm mx, when i tried to bind it to my stock sc10 esc, i had to switch the throttle reverse on because when i first pulled the trigger it went in reverse. then i binded it to my second truck with a novak havoc and a hitec steering servo and and to put both the throttle and steering to reverse on. is this normal? i have the original 3pm 2.4 and it didn't have this problem. any input would be appreciated. thanks.
