You can't beat the deal on Poly and Neo motor magnets going on right now on Dash's website $0.99

That is a good deal!
Which are stronger, poly or neo?
They say there will be no more made. Must not have been big sellers. Perhaps because too many rules forbid them.

Wow that is a great deal! Ecbill neos are MUCH stronger than polys. I have a lot more use for poly magnets than neos. Have a couple of sets of neo mags from nacho, but I have never really had a place for them. Going to try and order some of the polys before they are gone. Thanks Sam for the heads up.

neo magnets require very low ohm arms and the whole drive train must be reinforced to deal with the extreme torque

How do you think Magnatraction chassis would respond to Neo magnets?

Chassis, top plate, and axles would survive ok. But with the low ohm arm that would be needed along with the higher voltage the car would need, the wheels would need to be glued to the axle and the tires to the wheels or use a firm silly foam. Cluster gear, crown, and possibly the intermediate gear (if plastic) would be toast. Similar builds have been ongoing here with the 4g unlimited FED class. Extensive modifications have been necessary in that area. I think the AFX chassis would hold up better but the gears still would not last.

How do you think Magnatraction chassis would respond to Neo magnets? I have tried POLY & NEO magnets in the T jet, magnetraction and Non magnetraction cars with low ohm arms. I have had some success with them. Forget the Neos with anything over 1.5 ohm. The polys work for ET but it must be a 6 ohm or less and you will lose some top end over a good stock Dash magnet. If you could find a Poly that would gauss around a 1000 it would be ideal for a 6 ohm. Weakest link on AFX 3 gears is the Crown and cluster gears. Never had the idler or drive gear go but the drive gear must be a tight fit or it will spin off. Never did much with 4 gears but I did put a 4 ohm with Polys in one and all the stock gears are still alive in that one. At 20V that one runs in the .5s on my track with some of my tricks. The low ohm AFX/Tjet 3 gear cars are fun and fast but no one else runs them but me. Fastest one I have had ran in the .3s at over 40 mph. The pancakes arms do not seem to last at the high amp draws unlike the inlines. |

The Dash Poly & Neo magnets are very high strength, even the Poly ones are very strong. The polys read over 2000 and the Neos read over 3000 gauss. They will not work on anything but very low ohm arms. Still for .99 I will stock up on them for whatever. Thanks for the tip Sam, I just ordered a batch.
