They were the 1st out. They had them air shiped in so we had them for the race.

Any idea when they will be ROAR approved ?
I didn't see them on the list.

walterhenderson

To the best of my knowledge they already are. If not now by the 1st of the year.

You might be disappointed to know that you have to run the Yokomo wheels with their hubs. Also that you will need their arbor for your tire truer.

(I wanted their wheels to be different but after looking into the conversion I might as well just get a Yok car.....)

I have 2 12R5s with the same problem (one is a 5.1, the other is a standard R5). If I give them too much throttle at any time, whether sitting still, coming out of a corner or already running down a straight-away, they dart off in one direction (usually hitting a wall ). If I go easy on the throttle while picking up to speed, they drive straight. Both of these cars run on 2S so they have quite a bit of power although they are running 27t brushed motors. I have a 3rd 125.1 that doesn't have this problem, however, it isn't as quite fast as the other cars and runs a Tekin on 1S so power comes on very smooth. I can punch the throttle in this car whether it is sitting still or coming around a corner and it drives straight without darting off to either direction. The other 2 cars are very sensitive to any throttle changes so I have to be very easy on the trigger or they just dart off in one direction or the other.

I have rebuilt the diffs in all 3 cars with ceramic bearings and shcumacer grease so they are all very smooth without any slipping. All 3 cars diff's feel the same. I have checked the bearings, tried different tires, set them up on a tweak station, etc but the 2 brushed cars always seem to have this problem. Any ideas of what might be causing this or things I should check over? Is it just too much power coming on at once from the 2S setups? I have to be so gentle on the throttle with these two cars or they drive themselves right into a wall

Could you post pics of your 2s setups.

With 1s mod at the Nor Cal Nats this year we had no issues with traction.

At our local club in Camarillo where traction is low to medium, a 17.5 boosted 1s gives the same laptime as 13.5 boosted.
Traction with 12th scale plays a large part to how much power they can handle.
12th scale is more about corner speed than acceleration.

I have a 12r5 and for some reason the spur gear is so hard to spin while the thrust cone is tight enough to not slip, but my bros car and the other 2 we race with for some reason theirs is no where as hard to spin as mine any ideas?

Jimmy,

Thank You kindly for the reply, although I should probably clarify the request for information.

I typicaly use CRC Tires on my 1/12 Scale which places my overall wheel width to 172mm without any shims, I am mearly trying to use these different offset Hubs to achieve a range of hopefully (168 - 172mm).

Now it is my understanding the wheel pattern or in better words the Rear Tire Bolt pattern from either wheel Mfr. (CRC, Jaco, Yokomo, Parma) are all the same except for the offset of wheel depth.

Kind Regards!!!

The Yokomo hubs will make the car even wider.

The only solution to try and narrow the car would be to machine a little off the bearing surface by the diff ring and do the same on the clamp hub. I hope that makes sense.

Here are some pics of the 3 cars. The brushless car is running a 13.5t motor. I have only run it twice since getting it together and I haven't tried any boost/turbo yet on this setup. It runs a 1S 5300 SMC pack with 76t spur and 38t pinion. The other 2S cars run various RX packs from my helis. These range from 1300mah to 3600mah. I velcro them in since I use 5 different packs for these 2 cars but the batteries do not interfere with the side links (although I have to use 2 layers of velcro on the 3600 to space it up high enough so it doesn't interfere). The packs range in weight from 77g for the lightest pack to 153g for the 3600 with a few in-between (compared to 143g for my 1S pack). I don't add any weight to the cars which could be part of my problem. They have the same problem darting off to one side while giving throttle with all 2S packs whether it is the lightest/smallest 1300 or the largest/heaviest 3600. I had to space out the servo saver on the brushless car to keep the links from rubbing the servo. The other servos are 2-side taped on the cars although they feel very solid and have beeen mounted/run for a few months without coming loose. The brushless car is running a 9650, the R5 has a JR Z3550 and the other 5.1 has a JR3400. The cars are all balanced left-to-right when checked on balancing pins and don't show any tweak problems on my MIP tweak station.

Any help/advice/etc would be greatly appreciated. If you need any more details about the cars, please ask. I have lots of spare parts for nearly every piece on the car so if there is anything I should check/change/replace please give me some ideas. There are no other 1/12 scale cars at our track except for mine so there are no rules/regulations which is why I have some weird setups I have the 2 brushed cars setup on identical DX3S remotes to try and get some of the other guys involved in 1/12 scale but when they drive my cars, they usually hit the walls pretty quick since they are not used to feathering the throttle to keep them going straight. I thought the darting to one side was normal since the cars are light and 2WD until I got the brushless car on the track and it runs awesome without this problem. I can get them all around the track pretty quick, but I have to really work the throttle on the brushed cars and be very carefull not to give too much throttle at any time to keep them going in a straight line.
