winged we got to sit down and go over some one on one nitro couse hump pack installation is one of the easiest things to do besides changing the tire maybe ,but dont worry we all kind of started blind in this but most of us atleast had a manual with our first nitro rc and you bought yours used without a manual and jumped into nitro like it was a regular car turn the key and go ,but it isnt so in nitro little more patiance and learning is required and will take some time ,but trust me i know how much you are enjoying it so far just do a little more reading about it and you should be fine and dont forget to start a rc account couse it gets adictive very quickly most imprtant is that you are doing what you like so enjoy
