Don't take this the wrong way, but you probably need to take a litttle more time with maintanence and cleaning when it comes to your vehicles. You have to periodically check your vehicles for loose screws, stripped wires, broken parts before and after you run. These cars and trucks take amazing amounts of abuse, but will not last without some care and effort on your part. After I take my vehicles out I always clean them, check for broken parts, empty the fuel tank, use after-run oil, etc. Nothing is more frustrating then wanting to go out and bash your vehicle only to realize it won't start because you had broken a part or lost a screw last time you ran it and didn't notice. It's happened to me. Just spend a little more time maintaining your vehicles and you'll be alot happier. Again, I'm not trying to put you down, just offering a litttle constructive criticism.
