On the 12r5.1 you normally run the front brace. I noticed on some of the team drivers setup sheets, they remove the front brace. Does anybody know why they would remove the front brace?

Because they put sim under allu part and 0/5/10 deg block? to made longer
upper arm?

Or they need more flex in front end.

Why, don't ask, I have small experience.

I found that if you remove the front brace, and change nothing else you will have more front grip mid-corner.

Weird thing...

Got an older set of Jaco Purple front foams (they use regular bearings NOT flanged ones) and they work great still but a layer of foam is 'delaminating' from another layer. It is just under 42 mm.

Is that normal?

Ivan, the older rims are smaller, so you end up with a higher profile tire. Back in the day with the smaller rims, we'd run the tires a couple of mm smaller too. For the foam coming apart: Speedsew to the rescue.

Took a load of pictures at a National race meeting a couple of weeks ago, and I noticed after looking through the pics, that this R5.1 has a re-worked cross brace that helps to hold the LiPo in place.



Does anyone know if this is a factory part or was it a one-off by the owner of the car?

I also noticed that a few R5.1 drivers were also re-drilling the original cross braces so the tweak screws moved towards the centre of the car, touching down on the bottom pod plate, rather than the top of the side links.

Anyone else seen this??

Cheers.

Did you notice the blue alloy ball studs on the ends of the cross brace? Looks like there's been some experimenting with damper tubes.

I think it is actually the v-dezign cross brace

http://wwwmedib.kaleva.fi/plus/img/m...uto_pieau4.jpg

which is why the side springs can moved inward more like CRC Gen XL

I have some front foam donuts I wanted to mount, but the CRC rims I was going to use dissolved like aspirin when I put them in acetone, and some of the other rims I have around don't fit the bearings as well as I would like (Jaco), are too wide on the axle for my liking (HB, Ozcharge), or too flimsy in construction (TRC/Trinity). So, what does everyone else use? Are associated making quality acetone resistant rims for the car?

And why would you use acetone to mount donuts???

You normally true the foam off till the rim is about clean.
(optional step: use a very small amount of ammoniac to degrease the rim!)
After this, contact glue ( I use bison kit) on both donut and rim.
Leave it all to dry for about 20 minutes.
Then use synthetic paint thinner on the glue and slide both parts over eachother.
Let it sit and you're ready to true them after a day.

i seem to remember using lacquer thinner but the tire glue was not CA. i guess acetone is needed to remove CA glue?

i think CRC does offer their wheels new, maybe starting with a new set and using contact glues, you can avoid needing acetone to clean the wheels when new foam is needed.

for preglued wheels, like already noted, maybe a mechanical rather than chemical method would be better. i have accidently hit the rim truing very small fronts and the CRC glue seemed like it was pretty thin and smooth. just a little sanding on a tire lathe might be the easiest path with used wheels of choice?

Well, I use acetone because I have used acetone to take tyres and glue off rims for the last 10 years. 90% of the rims I have come across are acetone resistant for exactly this reason. The Jaco rims for instance. Usually it is only cheap low quality rims that aren't acetone resistant, I'm surprised the CRC rims aren't.

Using acetone has a number of advantages: you don't have to spend ages truing down the tyre and using up your truer bit, instead you put the tyre and rim in a can with acetone in it and come back half an hour to an hour later and the tyre slides right off along with the glue. The rim ends up much cleaner this way.

I mount donuts using a tyre horn and shoe glue with a little acetone, this is relatively easy, the tyre slides over the wheel well with the aid of the acetone, the tyre mounts well with a little practice, and you don't have to wait a day for the glue to be dry enough to true the tyre, an hour is long enough.

Anyway, I still need to buy rims, because I have donuts to mount and no rims to mount them on, and I would prefer not to buy CRC rims because I'd have to buy new stuff and change a technique that has worked well for me for a decade. So, does anybody have any other suggestions?
