IFMAR rules require: "No change to the rules or homologations will be permitted within four (4) months of a World Championship event, irrespective of the Section." As the host block, ROAR was only notified/consulted on this rule change five days ago, which is within the time period of the rule that prohibits the change. The ROAR President has asked for a clarification on this issue, especially regarding the implementation of the 3-speed transmission. It's curious based on logic alone, but a new transmission isn't something that you can produce effectively in such a short time frame. To say nothing of the fact that a 3-speed trans in the 1/10 class seems to go against all the basic principles on which the class was founded. Hopefully we'll have a clarification from IFMAR soon.

FYI - I also believe INS boxes will be required. Not certain, but I believe I read that somewhere as well.

There's what I read. ;o)

We received a reply that suggests the 3-speed may have been a typo. Clarification to come over the weekend.

I personally do not have an issue with INS filters being used...

I wonder if its technically a diff if you put silly putty inside of it? Its really hard, but you can turn the wheels independantly of each other. Although be careful not to twist the end off of a swing shaft,

It appears there's a consensus that the three-speed rule was a typo error that survived too long before detection, and potentially spools, open diffs and one-way front axles will be permitted. I would wait until it's published in the rulebook for sure, but it looks like all will be well in the universe. ;o)

When Jim says that it usually means that he has a set of rules he is going by for the particular race he is at. It doesn't mean that they are the same everywhere he goes. Just that he is going to enforce the rules he has in hand.... In other words, if he was running this race, he would be given these rules and it would be "Rules are Rules, they don't change"
amen Sean

right or wrong they are the same for every one

5.1 The class run will be the 200mm Nitro Touring Car which will be 4WD. Only one (1) brake, working on the central power transmission, is allowed. No second or individual brake system(s) for front and/or rear axles or single wheels is allowed.

5.27 Not allowed:
 Solid front axle drive assembly (the front wheels must able to rotate independently of each other)



So spools are out clearly. oneway is legal because they can spin in one direction independently of the other. diff is legal, how close to jbweld can you get before ifmar considers it not independent.

btw, with regard to the 3 speed.. does this mean two on the gear and one in a transmission is possible? not that I would, but the wording seems to be there.

5.2 Maximum 2-speed gearbox allowed.

5.27 Not allowed:
" No more than 3-speed transmissions."

5.27 Not allowed:
" No more than 3-speed transmissions."

So, that means 3-speed trannies are mandatory now?

That's not good.

No, no, no. You guys are putting out bad information. IFMAR hasn't published a correction to the rules yet. Brian, you're reading the old rules as they were BEFORE this was brought up for correction. All you did was read the old rule that IFMAR is currently revising and get these guys whipped into a lather for nothing. Please be patient and wait for IFMAR's publication of a correction. Not one that happened two months ago, but THIS MONTH.

Ahh sorry I was trying to clarify the last page that I read and only had the ifmar site to go by since I am not as closely in the loop as the rest of you and the rules do not really matter to me because the change is so minor I can just adjust to them at the race since there is the potential for the last minute track site vote.

1/8th is currently listed as "1:8 IC Track rules down for rechecking" so I assumed the rules posted "1:10 IC Track 100309" (3/9/2010) were the rules for this year but what RC organization really keeps their website up to the minute anyway.

What is there really to correct though? spool or not is just drivetrain weight even if you want a spool, its just a diff with 1mil oil since it technically turns. the 2/3 speed thing is just written weird is the only reason I brought it up because it was funny.

Default NEW INFORMATION POSTED

Good morning everyone,

As we get closer to the WC, IFMAR is finalizing it's list of approvals and rules. We understand that there is the possibility that a revision may be made to the 1/10th Rules that we we recently posted on our web site. IFMAR has informed us that they will send us a revised copy to post once the issues are resolved. I wlii also post an announcement to this thread letting you all know when it is posted.

As for NEW information, IFMAR just sent me the "APPROVED LISTS" for BODIES, MUFFLERS, and INS BOXES. These are now posted on the web site under the "World Championship Info" menu on the "IFMAR Rules" page.

See you soon in July,
