Idle problem

[Brimor]

Hi, I am having trouble with my used rampage xt I just bought. When I start it up it idles at wot. The person I got it from had a lipo battery in it. Would that have made the stock servo go bad? I've tried to adjust the idle and reposition the servo horn but no luck. Feels like servo horn may be a little loose also. Any help would be appreciated. Thanks
