Thanks guys, unfortunately, I bought both of my specials used and didn't get the extra stuff on the parts trees that wasn't used...

I have a racing buddy that probably has a few though. I think he has like 4 Specials...

Maski, I have a tool that allows me to replace the oneway bearings in the Yokomo (and others) oneway housing. You just have to pay for the bearing(s) and $5 + shipping. It usually costs around $9 per oneway bearing and most people get both bearings replaced. It's cheaper to send them in a padded USPS envelope. Ask your racing buddies if they have any oneway housings that need fixing and send them all together. It saves on shipping. I have paypal or take USPS M.O.s. My shipping address is on my website- BigDog Graphics

Some people have had no problems with the older front one-ways. They are lighter, so they would give a little better acceleration, but I don't think it is noticable. I have a HD one-way, and I think the design is much better than the older one, the shaft attached to the cups does not taper off like the old ones, so the one-way grips the whole thing. Also there are no reg. bearings on the sides, it is just one-way all through.

Well, I am using the one way on carpet. I have been racing my special in stock class since first of the year. I am pleased with the durability of the car in general. I seem to like a particular wall at my track, and have hit it dozens of times. Only broke the arm 1 time, and then it bent the cvd bone slightly. I left the bent bone in there, as in stock class it did not seem to have any ill effects. I raced the car in mod also last weekend, hit that wall again and bent the bone worse. I have another car I bought from a guy at the track, so I took the bone off his car and put it on mine. I hit that darn wall again and snapped that bone in half. In all fairness, it may have been weak to begin with, as it was the bone from the same location (front left), and im sure it had hit the wall a couple of times when he drove it.

The only odd thing I have had happen to the car is I have lost kingpins on the lower front. Two have disappeared, and I did not notice it right away. I am now putting threadlock on the kingpins hoping they stay in.

Man the cvd bones are expensive! $12.95 for one bone from Stormer Hobbies. MIP also shows them as part #1340, for $8. I had my lhs try to order me one.

Ras, the thing about the kingpins is the steering blocks get stripped pretty easily. You have to be very careful not to over tighten the kingpin screw when you thread them in to the block the first time. It only takes one time to strip them out and then you'll start losing kingpins.

Mo, thanks. I did not strip them, just did not tighten enough, or maybe it is because of all the right hand turns on our track. It was the left front that fell out twice. Anyway, I also found a Lundsford part # 8271 for titanium kingpins. I ordered some of those since I need them anyway.

Default Center One-Way Wear

Have any of you noticed that the gear on the center one way in the speacial wears really fast? For the past few months I've been racing mod with my yoke, but not weekly and recently noticed a lot of belt skipping. I took the car apart and when I saw the center one-way it looked really bad. Is there a solution? Or will I have to spend $40 dollars every few months to replace it?

Get the hardened one way pulley PN: ZM674H. It should hold up for you.

kentech: I was just thinking about you the other day. How are things going now that you are working for HPI? How do you like the Pro 3 compared to the Special? Be honest, we won't tell anyone.

Hi guys. Greetings from Malta.

Kentech, good to read you again! I haven't been in much recently, partly because I have been unwell and have not felt like doing anything, and partly because the time I spend on rctech is spent in the Formula 1 thread in Chat Lounge. It's a good one.

Geppetto. If Kentech says he has the HPI because he works with the firm, we will understand it. He doesn't have much choice.

However if he says he prefers it to the MR4 then there must be something very wrong with Mr Hirosaka, Mr Hara, and all the other World greats. Look at it this way Hara beat the World with his MR4, including beating his No 1 Masami. Since changing to HPI he has won nothing, despite changing the car out of all recognition. Somebody reckoned there were no more than 6 original HPI parts on Hara's car. The rest were all one offs. And they still can't get it right.

Is there any truth in the fact that we could see Hara driving a Schumacher Mission at the Worlds? I wonder why? I suppose it would increase his chances.

Regards

Joe from sunny Malta.
