After 2 days of owning my Bit Char-G, I noticed that I wasn't getting much steering responce.
So I opened it up, making sure not to break any wires (I tried this many times on my now dead Skyline, and I was successfull) and I noticed that the steering magnet was near falling off.
So I took out the steering what-cha-ma-jig and put the magnet back in after having it fall out. So I picked it up, wiped it off with my finger, and replaced it. I made sure everything was back the way it was, and I re-assembled it. I drove it right off the table, because the steering would not come back to the middle.
It won't come back to centre...
Can anyone help?
PS: I re-assembled it back to stock, making sure that everything was where it was supposed to go.
Thanks for any and all help that you may give.
