Is it something like WD-40 that you'd just spray on the bearings? You dont have a part # for it do you? Seems like most of Tamiya's lubricants and greases are high quality...

I guess it could also be a bad mold on the belts or something, maybe the fibers arent straight through the belt, that may cause the problem.

I have yet to flip a white belt, and all I run is a 6 turn motor, so maybe I have just gotten lucky.
Yea ive only flipped my front belt once an that was at the Hpi junior nationals running mod when i managed to hit a flipped car at the end of the straight at full speed Although i think it was beacuse my glass fibretape snapped and the cells hit the belt. Other than that its been fine.
I run my belts at.....

Stock indoors -1 -1
Stock outdoors -2 -2
19t indoors +1 +1
19t outdoors 0 0
Mod indoors +2 +2
Mod outdoors not done that yet but i rekon id stay with +2+2 just to be safe

So far ive only stripped 1 bets an that was wen i accidentally ran +1+1 in mod indoors

I'm not sure what the part number is. They were handing out the lubricants once the car passed inspection.

Just wanted to reply to this. First of all RC4Less bearings are NOT of a better grade than Acer Ceramics. Acer Ceramic bearings are made to tighter tolerances. Contrary to popular belief the lower the Grade number a ball is, the rounder and smoother it is.

Second, there will be no issue of interferance or increased friction due to the seals.

These are basically perfect bearings. They might seem a little tight upon breakin (no tighter than any stock bearing) but once they break in nothing can touch them and they will last you forever. I ran a set in my TC3 for three years and never had to replace one of them. I only cleaned them twice a season and that was more than was necessary (yes the seals are that good!)

If you don't go with the Acer's visit SpeedTech Rc and go for the Yokomo Ceramics!

I used to run the Acer bearings when they had the hard plastic seals because I could just shave away a little material from the inside of the shield, and it wouldnt contact the inner race of the bearing. I guess they switched to more of a rubber shield on their new bearings though, and although that has the best seal avalible, it will not spin as free as a metal shielded bearing that doesnt make contact with the inner race, ceramic or not.

I agree the Acer ceramics are good bearings, I switched them over to metal shields and didnt have any problems. But for now I just want it to be a bit easier and I'll use the Speedtech bearings that already have metal shields.

I knew the hundreds and hundreds of pics we took at the worlds would be of use someday!!! Check out the name on this baby... Japanese profanity?

Apex,

I assume you're talking about the front of the 415? Many have post setup on how to piece one together using Yokomo outdrives. We have drawings down to CNC Machine steel ones, however, we are tied up at the moment making spools, so this might come a bit later (few months from now)

Patrick blew out last weekend, but he should be there this Sat, I'm gonna keep the delrin outdrives for spares, but if I can just exchange the C-Hub for Spindles, that would be great.
Hi Randy,

I did receive your email by the way, and I'm sorry I haven't had a chance to reply. But I'll look for Patrick this Saturday, and I'll give you a reply also about the bearing prices. I guess you won't be making it this Sat? Suppose to be a good crowd this Sat

hapiya,

front spool is more of a tuning option. Under certain conditions, they can be better than one-way, but under certain conditions they are not. Usually I see guys run spools on larger, flowing type of tracks, and one-ways on tight twisting tracks. Just my observation

We should have more spools available in 2-3 weeks as they are getting ready to be heat treated.

I cant make it tomorrow, but I did manage to get the following sat off. There will propably be a good turnout because of the rain, but I doubt there will be much of a pro-mod class since everyone is at the Novak race, so it wouldnt work out for me too well.

I'll get in contact with Patrick today and give him the C-Hubs, thanks for doing the swap for me.
