Default CEN Matrix suggestions

I am looking to get a new CEN Matrix in the next month or so. What would be some good little upgrades for it? This is going to be mainly a backyard runner, I *might* hit a race or two if I have time. I can make some stuff on a lathe or mill, but since they aren't CNC I can't get too detailed.

Also, I would like a fuel that has a higher oil content. I've seen some with 9% and 11% oil, I would like a little higher unless this is the norm now and its fine. I remember before 16% was suggested, but I know fuels/oils have come a long way.

If the higher oil content is not available anymore, would it be suggested to add some Sig oil to the fuel? If it doesn't make every last drop of power that is fine, I want a little cushion to make up for my n00b-ness in tuning. I think I did OK with my Thunderquake, but I'm sure this is a different beast. Plus I need to learn how to control all the power of the new .28 engine in this buggy, so a little lower power wouldn't hurt anything to start.

I will be getting the RTR version.

What does the upgraded bell crank and the steering knuckles do/prevent/help?

The knuckles will give you plenty steering throw and the CNC bell-crank will not break as suppose to the plastic version. Though it didn't break on me when I was using it.

The plastic bellcrank breaks easy, the aluminum one never does. The knuckles can break but most importantly they (aluminum), give your better steering. Extra shock shafts wouldn't hurt. There's two little black pieces of plastic on each shock mount, they wear down easy and shock bladders are good to have extra of.

I think I'll run the stock stuff and if/when it breaks I will get the aluminum upgrades. $69 for knuckles is a bit much for now. But if the options are a set of plastics that will break again, I will definitely go for the aluminum ones.

So what oil percentage is the Sidewinder and Byron's Fuels? Has the oil technology changed to where lower percentages can be used and the same level of protection can be achieved?

I believe the oils are 11% and 12%. I'm not sure about sidewinder though. You don't have to buy the CEN upgrade parts for $69. On amain and other sites other than CEN direct, you can get them for around $50. Although, if you will be getting something upgrade parts, I suggest that the steering knuckles would provide the biggest performance gain. They are shaved down allowing a whole lot more steering throw.

Byron's Race Fuel comes in 9 and 11%. I'm not sure about Sidewinder, I never used it.

Use the stock knuckles. Once they strip then upgrade to the aluminum ones.

I have these two parts for sale.

http://www.amainhobbies.com/product_...ducts_id/12790

http://www.amainhobbies.com/product_...ducts_id/12819

The 19 degree front hub carriers are new in the pack and the aluminum upper ballcrank is new but not in the package. $60 shipped for both.

I also have a set of Gene Hickerson's turnbuckles.

http://cgi.ebay.com/CEN-Matrix-RTR-F...QQcmdZViewItem

The ones I have are new but they are the ones that have not been anodized. $25.00 shipped
Pm me if interested.
