NEVER SET ANY SETTING ON THE RADIO ABOVE 100%!!!!! this will instantly fry servos because the servo wil be trying to swing further than its full potential. you must set your epa(end point adjustment) or else you will just keep going through servos. to set your epa on throttle. you must take off the air filter and set your epa just so that your carb is open all the way. it could be 75% it could be 98%. if you have to go more than 100 you lincage isnt set right. same with steering. you must adjust it so if the wheels are turned all the way. the servo stops there.
