i would have to advise you to learn all componets and their function, you can learn alot and if your gonna stay in this hobby your gonna need all the info you can aquire. having a nitro mt is alot of work for play. and maintance/repair is something that is going to take alot of time and patience, mainly because its a necesity to run these trucks. everytime i run i spend a good 30min working on my trucks, thats if everything goes fine! you can spend alot more time wrenching if you break. but somethings gonna break on offroads especially the way i drive mine, thats when i usually call it a day. even if you just run around the yard and up and down the street your gonna break stuff. you really need to understand how much work is involved in keeping up offroad nitros.
