The stock tires are within the size requirements that is why CEN went with that size of tire.
So, if you can legally upgrade the chassis, suspension, and engine why can't you upgrade the wheels and tires? Better yet why can the other trucks use whatever wheel and tire combo they want but you can't?
Did you happen to ask what the justification behind that reasoning was?

I didn't question it further to be honest. I decided to renew my idea of fitting wider arms and bigger wheels to the JT chassis so as to meet all the requirements of the class, rather than try to argue my way into acceptance. I am thinking it will be far more satisfying that way when I whoop their hides with a truck they tried to ban!
I could very easily race the Savage in the unlimited class but I am totally determined to race the CEN simply because they said I couldn't. Just plain stubborness I suppose.

Thats right use the rules against them if you can. It should work for atleast one season.
Other than wheels and tires how doesn't it meet the class requirements?
Or are you talking about racing in another class?
I have downloaded the rules from ROAR and from what I can tell the wheels and tires are the only problem but the sanctioning body might be different over there.

I have e-mailed Proline to try and get some clarification as to why hopefully they will respond.

I was trying to get the truck legal to run in the small block class but I have just got the rules listed and it will not be possible to run the truck here at all. The main stumbling blocks are the rules against running 'converted low chassis trucks' and the one stipulating that a truck must have stock transmissions and differentials. My plan was to change the diff housing to accomodate wider arms and then fit a hub that will allow bigger tyres to be fitted. This still would not make the truck fit within the guidelines of the small blocks but unlimited class allows 'hand built' trucks to compete. Looks like that is the only way to go. Maybe I should just run the Savage, it will be alot cheaper and simpler in the end.

Don't give up on the CEN. Race the Savage now because it is ready and you could probably race this weekend.
I believe poorjudgments mod doesn't modify the differential so that might be worth looking at.
Does switching the CEN over to T-Maxx size wheels make it a converted low chassis truck and would it be if CEN sold the adapters as an upgrade? I'm not exactly sure what a converted low chassis truck is.



rolland

I think if the manufacturer makes the upgrade then it would be considered stock, if you make the conversion yourself then it is thought to be a home conversion. Thats the way I see it anyway. Seems like the rule makers have gone to an awful lot of trouble to make sure certain trucks can't compete, even going as far as to name CEN trucks specifically. Makes you wonder what they are so scared of!!

A sub 300.00 dollar truck beating a 480.00 dollar and up Revo or other similar truck.
You know people were upset when CEN won last years Pro-line, probably for that reason.
I can just imagine "how can that 250.00 piece of garbage possibly beat my 500.00+ dollar truck".




rolland

You know, if they saw me drive, they probably wouldn't be so scared!

New update. The unlimited class is now not open to 'CEN type trucks'. Looks like the Savage is going to be race prepared after all!

i've been having the same problem for 2 years now.. I can only race unlimited, but I get classed with big block high dollar monsters... Funny enough, the truck is still very competitive.. last week i raced some 1/8 scale buggies... Mayhems and inferno's... did pretty good except for the huge jumps.. Its not made to sky 20+ feet ... my speed was the same so I was pretty happy and they were surprised at the little truck... I just have to get larger tires on it to help the handling.. I was forced to use 2.2 pins.. too small for the truck but thats all i could use at the track....

Here's a link to some adapters that might help you out http://maximizerproducts.com/mtr.html
I know some people don't advocate the use of adapters for maxx size wheels on the CEN but if you stick to a low profile pin tire it shouldn't have that much more mass than a stock MT2 tire. On CEN's race truck I read somewhere that they cut out the center of a stock wheel and put it in a maxx wheel so they could use larger tires. That is alot more complicated than using adapters.

Just to let you know what we are up against over here, I thought I would post the generally accepted rules of MT racing over here in the UK.
Small Block Class
Types of truck included in this class~ TMAXX, TMAXX 2.5, TNX, REVO
No big block .15 engines
No medium block .21 engines
No 4wd stadium style trucks (this includes CEN type trucks)
Bump start ok
Any .12-.18 small block ok
Any suspension mods ok
Any exhaust system ok
Must utilise MAXX size wheels and tyres min diameter 5.1" min width 3.1"

The Unlimited class has different rules obviously but the ones that relate most directly to CEN are these-
No small block engines allowed
No 4wd stadium style trucks (this includes CEN type trucks)

So there you go, pretty cut and dried. These rules were taken from the Maxbashing forum, but it certainly seems that most UK clubs use a similar set of guidelines and the BRCA has the same rules with regards to the wheels.

no prob scouser - just bung a big block in there!!!

how annoying is that tho? whats a 4wd stadium style truck? erm... its a mt to me with lower suspension and/or smaller wheels. why the hell u cant just change those and run seems very odd to me mate. bloody politics eh...?

Its not like the CEN is drastically smaller than its rivals and at the moment the small block class is only open to two manufacturers, Traxxas and Tamiya. I thought that by raising the idea of opening up the class to converted cars like the HPI NMT2, TT SSK, the new GS truck and even converted HoBao buggies, it would inject some life and certainly some excitement into what has been referred to as the "Revo race". Personally I can see no negatives to widening the guidelines of the small blocks but its not my decision so there isn't much I can do about it sadly. All I know is if they did allow the CEN to compete, those people that spent £400 on a Revo would be crying into their beer!

I personally have no idea what a stadium style truck is. I mean if you look at some of the Unlimiteds they are similar to CEN's. Flat chassis with a low center of gravity. XTM Mammoth, GS Storm SUT, and Hot Bodies LSP for examples. In fact for the most part the SUT and LSP are converted buggies.
I think it all boils down to the wheels for some reason or another and whether the manufacturer supplied them with the kit or as an upgrade or not. Why you can't just change them to comply and race is beyond me.
Maybe over there the word unlimited has a different meaning than over here. Here you can race in unlimited if the tires comply, and the stock ones do.



rolland

i just want to put in my two cent. that is messed up you guys should be able to race. don't change your trucks they should change the rules fight it.[>:][>:][>:]

.

Rolland, the GS SUT, Hot Bodies LSP and all other buggy conversions, race in a class called 'Outlaw' over here. The defining characteristic of an outlaw truck is the inclusion of a centre diff. Obviously the FF has no centre diff and is therefore an MT, or so you would think. The defining factor for the exclusion of the CEN and all other brands offering a similar truck, seems to be that they are based on a flat chassis plate and run 2.2" wheels.
The rules for the small block class must have been changed sometime over the past twelve months because initially (about 18 months ago) I was told that the CEN and other 1:10 trucks were allowed to race as small block mts'.
aj, hopefully we wont have to fight it. A class that allows only two manufacturers to compete is doomed to failure, especially as HPI have just released the NMT2 .18SS, which should prove to be very popular. If the new owners of these trucks bring some pressure to bear then the rules may be relaxed to include our trucks once again.

The rules here are pretty much the same as over there but the mammoth's lsp's and others race in the unlimited class also. There might be an outlaw class here but I have never checked.
As far as fighting the rules we are the minority so chances are we will be at the losing end of that argument.

Over on the teamcen forum there is a poll about building a 1/10 scale competition truck so they might be considering one or maybe MT2 uprades at least that way the MT2's would be legal.


rolland

If any of you have looked at the new RC Car magazine, they were trying to figure out a way to solve the problem of MT and truggies racing in the same class. They made this project LSP that was very light and had the very small panther cheater tires on and everything and they said that it was totally legal with ROAR rules. Well they came to the conclusion that truggies were unlimited "stadium trucks". Well, if there now a stadium truck then why the heck cant we race our so called 4wd stadium style trucks?

We can race unlimited in the states. But we can't race 1/10 scale monster truck. In the UK they can't race either.
With the exception of 1/10 scale monster truck all of the monster truck classes are new and the rules are going to be changing until they are clearly established and almost everyone is satisfied with them.
I think that there is eventually going to be a truggy class seperate from the unlimiteds.


rolland

This whole thing is quite confusing. The Traxxas TMAXX and Revo are both 1:10 scale but run monster truck wheels. They have a different chassis design to the CEN but really it's the wheels that are the difference. The required wheel dimensions are specifically designed to remove the possibility of trucks with 2.2" wheels qualifying to race. Even the new Proline Moab tyre is 5" tall and 2.25" wide and they are the biggest 2.2" sized tyre I can find.
It will take a change in the rules to open the window for CEN and similar trucks to race small block. The problem is that I cant see that happening until the "my Revo's faster than your Revo" class, gets boring for the competitors.

I believe the Masher 2000 is the largest or they were when I was looking for tires for my Stampede. Still they are considerably smaller that the stock MT2 tires. Imex might have something larger it might be worthwhile e-mailing them to find out.


rolland

Those Prolines are just .1 of an inch too small in diameter for the class. Thing is though, imagine the ballooning you will get from them. The side wall flex would be ridiculous and I doubt the gearing for the MT2 would be too happy about the final roll out ratio.
I have decided to race the Savage and thrash the CEN around for fun. Its a shame though as I was all set to sell the Savage and go nuts on the Fun Factor making sure it was totally race prepared.

I have a set on my electric stampede and they do baloon quite a lot.
Imex's All-T Tire is supposedly 5.5 inches tall and 3 inches in wide.

Still it might be easier to just race the Savage. It will be alot easier to make it comply with the rules.
