Was just looking at SCI where they were discussing something called HOPRA and their rules. Seems like no one can answer what kind of magnets are allowed in some class they run, about 4 pages of discussion. What a mess. Glad we have the rules we have here which are obviously much clearer than whatever that organization is running.  |

I really am liking the rules format that we have now.

Hey Guys,
The magnet bs happens every couple years in our HO road racing. HOPRA is a good organization, it's mostly peoples misinterpetation of the rules that lead to the most confusion and it dosen't help that people who have no interest in N. American racing constantly bring up things that have no bearing on actual building and racing.
When the rules mandate ceramic motor mags, as is HOPRA S/S, what they mean are the original ceramic mags that were available from the HO set and car manufacturers.
So if you're building a BSRT G3 chassis or a Viper V1 chassis, the motor magnets would have to be original Tomy Super G+ mags.
The best magnets are found by searching thousands of orig. Tomy motor mags. The best "Pro Racers" have access to these special motor mags.
When BSRT came out with their ceramic grade (C4) motor mags around 2011???, they were allowed in most series S/S class and they really evened up the field cause the mags didn't need to be sorted. They are very consistant. But after a couple years, some organizations went back to orig. ceramic mags.
Advantage to the racers with access to really good matched sets of orig. Tomy ceramic Super G+ motor mags. These are available to racers that want to spend big bucks on motor mags. On most local levels the C4 Ceramic Grade are the way to go.
I'm liking the looks of the rules here.

The rules here are clear as glass in my opinion. I also admit that a G3 or Viper chassis, which is supposed to be similar to a stock Tomy Super G+, is superior. I have many Super G+ chassis and quite a few G3s and there is no comparison between the 2 when using all the basic parts that come with the chassis from the factory and both are running a 6 ohm arm.
When I run a stock Inline class, that class will be running in April, I do not allow those chassis for that reason. I do allow them in 2.5 modified and they prove superior there to.
If I were worried about magnet strength I would simply use a lift test to eliminate the problem. I bought a lift tester on E bay for about 20.00. You could use a gauss meter but they are expensive and many racers would balk at spending that kind of money.

One way to get the better Tomy motor mags is to buy 1980 - 1990's Japan market only Super G+ cars, usually the ones that came in the hard plastic pit cases. The Japan only chassis are stamped J03 on the chassis. They included factory matched ceramic motor mags and the double dot trac mags. But is it worth it?  ? |

So if you want to get better magnets that are considered stock you have to buy cars that are most likely a lot more expensive than regular Super G+ cars. Instead of being able to buy a comparable magnet for 8.00 that is not made by the factory.

Yeah, unfortunetly a lot of those Japan only cars are locked away in their little plastic boxes, for display only. Their owners are probably not even aware of the factory matched motor mags. But if you buy used cars on ebay, look for the J03 stamped chassis. They are the older black chassis. They'll usually have the double dot trac mags too. And look for the metal rear axle retainer.  |

You made me look..
Out of the 30 or so I have most had the double dot on the magnets many had the axle retainer which I had removed, but none had the J03.
