I have an XT and was wondering is there any way that I can adjust the throttle so it won't go very fast? I am trying to let my grandson run this and it is just too fast for him. Right now I am having to operate the throttle while he steers. He is only 5 and I want him to be able to hold the controller and play with it without me holding on to it. Thanks for your help. Oh this has the stock throttle servo and controller
