Superfist, It was a stock SG+ arm, they both are. Whatever the ohms are on that. This is what I thought was odd. The arm I popped in was from an older black plastic SG+ chassis that had cracked. It was a good running car. Not as fast as my current favorite chassis. Not even sure why I switched arms. But when I put that older arm in, like I said it just flat out ran everybody. I later raced one of the guys who had a rtr BSRT, and he was the...

when you replaced the arm, which end bell did you use? the one from the broken chassis or the one from the race chassis? some end bells (like ones with nicely broken in brushes) can make a big difference. since you dont ream your bushings (which i do but think is a pain) you might consider buying pre-tweaked end bells (scale auto) or pretweaked bushings (scale auto or scale engineering) some guys like the blue poly bushings, i like the brass...

Thanks to all for this post!!!More help for me!!ENTER TYCO!!

Plenty of good technical information here, but for the average layman it can be confusing. Lets try this: DC voltage uses a positive and negative connection. I think all of us have seen what happens if you cross those connections; you get a 'short'. With a slot car you are basically shorting those connections to make the motor turn. The amount of wire inside the motor is very long so the short is spread out over all that wire. Any...

Quote: The principle of resistance is how you control your slot cars. A controller is a device for controlling how much resistance is in the electrical path to the car/motor. This is only true for resistor style controllers, i.e., set controllers and Parma and the net result to the motor is a variable current source. The downfall with this style controller is the fact that controller reacts to the current draw of the motor. This causes the...

I have put tires on the rims, on a spare axle rim setup and run them at a slow speed in a dremel and trim the edges with an xacto knive, you can then also sand them down to size and round-over the edges.

Jeff's right. You have to spin them up on some kind of mandrel at slow speed. Some compounds cut easier than others. It's handy to keep a set of calipers ready or at least a go-no-go tire guage so that yer work is even side to side. I use PVT tires exclusively on my HO projects. They grind nicely with 180 or 220 grit sand paper. For narrowing or cutting I use sharp scissors and then grind the rough edges off after they have been cut...
