I use the Much More Joint Lube (the name sparked my attention on a shop site and I got some in. It is the thickest oil i've ever used. It seems to coat the joint very well and resists being flung off).

I have done a build review of the T3 2012 on my web site... had my first run with the car and was very impressed with how it handled using the kit carpet setup out of the box.

You can see the review here; http://rcracingni.co.uk/?p=1642

Any comments appreciated (or anything that I got wrong )

I found the black grease to be very good. It seems like it has Moly (Molybdenum disulfide) in it which is what you want in a grease for this type of joint. Not sure the % amount, most greases will have 3% to 5% of moly.

By nature of the beast any CV joint needs grease and needs to be cleaned and re lubed often. Just the way it is.

This is a good question. I have found that back to basics is best so far. Outer all around (like H1/L1 setup). On a very tight indoor circuit I race at, the longer links seem to make the car very lazy to drive. On the bigger tracks with wider corners, the longer links seem to work better. I just wish this car was a lot less stuck, as it really slows itself down on high grip conditions compared to the 11 and the push, especially at high speed is a bit frustrating. Its just part of having a new car that need tweaking to suit.

Default CPX Setup

Does anyone have a decent carpet setup for rather technical tracks and Vtec CPX tires?

Default Bump steer

Hi,

Could someone please explain bump steer? How does adding or removing shims under the steering block effect the cars handling (steering on entry, exit, on power, etc)?

Bump steer is caused by the steering link being angled up or down from the center of the car. If you have bump steer in the car during corner entry (when wheels are turned) and when the suspension is compressed it will usually cause the inside wheel to turn more and usually abruptly causing the car to be twitchy and/or scrub speed. By taking it out the steering is smoother on corner entry and over bumps.

Not the best description but what I feel in my own words. Mostly attributed to 12th scale. Its usually not as noticeable in TC.

Hi Matt,

Bump steer is controlled by the angle of the steering link in relation to the lower wishbone. If they are parallel then you will get minimum bump steer.

Looking at the links from the rear of the car at rideheight...

If they are angled up towards the outside of the car (more than the lower wishbone is) then you will get toe out during bump.

If they are angled down towards the outside of the car (again more than the lower wishbone is) then you will get toe in during bump.

In full size Motorsport most cars run zero bump steer to make the car more predictable over bumps.

In RC touring car racing, because most of the tracks are super flat, we often use the bump steer characteristic as a tuning aid during cornering. In this case the bump steer setting has the greatest effect mid corner when the chassis is a max roll...

With the T3 2012 I believe 1mm spacers are the kit setting. This gives quite a lot of toe out on the outside wheel during cornering, which results in smoother/less mid corner steering. If you run 2-3mm spacers then you get less toe out on the outside wheel during cornering, resulting in more aggressive/more mid corner steering.

Unless the car is too snatchy mid corner, I always run 2 or 3mm spacers as they tend to help maximise cornerspeed.

Hope this helps
