Hello, MadFox. There's a remarkable wealth of knowledge here on RC Tank Warfare, so there should be
no problem getting you some help. But for starters, bop on over to the "Introduce Yourself " section (
viewforum.php?f=42) and give us an idea of exactly what Tiger I you have (i.e. HengLong? Taigen?) and maybe show a picture of the innards so we can identify the version of the electronics. It helps us to know, too, what RC experience you have. Even if you haven't any, that just puts you in the league with many of us. After you do the introduction, you'll likely find advice galore and probably start a bit of good-natured fun, too.
