Hey guys, another rule change discussion is underway:

It is proposed that we bring the 1.9 class measurements into closer proportion to the 2.2 class. These are the changes being discussed.

Increasing wheelbase from 8.5" to 9"
Increase trackwidth from 8" to 9" to easier allow TLT axles to be used
Increase the voltage limit to 3s lipo to keep motor temps cooler

Please let me know your thoughts so I can vote accordingly.

im all for it Josh, ive read where some clubs are allowing 3s on a local level & adding a 1/2'' to the max wheelbase would really help these lil guy's climb.

if trackwidth is spread out to a 9'' max will gate spacing change also?

No change to gate width is proposed, it will still give the narrow MRC the advantage as far as that goes. It will just open up more options for axles.

MrDublin · 10-13-2009, 02:09 PM

If nothing else it opens up a lot more wheel options for me. The greater wheel base will help me a lot with articulation and suspension setup.

In other words I like it

Heard some talk about this, and was wondering so if this pass's do have to have a wheelbase of 9 to compete?

ROSS · 10-13-2009, 02:20 PM

sounds good to me josh.

9" will be the MAX wheelbase, just like 12.5" is the max in the 2.2 class.

Mini · 10-13-2009, 02:32 PM

Sounds good to me an extra half an inch can only help on climbs and reaching too. You got my vote!

And I would count it if you lived in MO

Find your local rules rep and let him know your opinion.

RivBlueNoma · 10-13-2009, 04:08 PM

So now this isnt going to be the sportsman class either?

Im ok with the 3s option but not good with the wheelbase and track width changes. I think it would make things harder for newbies trying to come out and compete with a new MRC which pretty much suck in stock form as it is.

Personally I don't like the wheelbase change for that reason. Trackwidth I am fine with because if you are using different axles you are building custom anyway.

Got my vote on these changes..Seems to be an acceptable and well needed change for the 1.9 class.

Increasing wheelbase from 8.5" to 9" .

ok maybe will help climb but will hurt the new guys with no way to fab
not sure about this one

stock TLT's can stay under current rules with narrow wheels
to give more wheel options so I guess

how does more power keep motor temps down?
just see this as a benifit to TLT guys 3s on a MRC seems like overkill & make breaking things a whole lot easier

Harley · 10-13-2009, 08:00 PM

I don't like the wheelbase change for that reason. Making a stock MRC even more worthless is a horrible idea.

trackwidth change would help allow other axles, a tlt is VERY hard to keep within rules with competitive tires.

3s lets you gear down and not have to use so much power from the motor to do the same task. This keeps motor temps down. 3s on my near stock MRC made it a lot easier to control.

I would rather ditch all the changes than except than all. I would like to allow the trackwidth and 3s rules to pass personally though.

RivBlueNoma · 10-13-2009, 10:04 PM

I think TLT's arent that great to start with, the turning radius sucks and the diff housing hangs down pretty low for 1.9 comp use. Not to mention they arent terribly durable in stock form. They might hold up to 1.9 comp use until they start throwing 3s at them. Mine use to snap stock shafts if I even looked at them wrong. From what Ive seen TLT hop up parts arent that plentiful these days and not cheap either so why not just build an MRC and be performance and money ahead? Sounds like somebody on the rules committee has a few sets of built TLT axles that they refuse to sell.

I agree. Id rather see none of the changes get passed.

fordwheeler · 10-13-2009, 11:38 PM

as far as a new guy bringing a stock mrc to a comp wouldn't the same be true for a guy that brings a box stock ax10 RTR to comp in 2.2?

I'm pretty sure you guys wouldn't turn him away & tell him to come back when his rig is built to the hilt! most of us if not all would help said person out & show how/where to make improvements. this is how we learn!

i was the new guy at the beginning of this season (had never even tried to drive it between a set of gates before) & my mrc is still based off of a stock type chassis & does a decent job when I'm having a good day!

everybody welcomed my bro & i to the club & showed us what to do/how to improve our rigs & were both tied for second place for the time being!

i really don't see a problem w/the possible rule changes

Are that many people using TLT axles, that we have to change the rules so they can be competitive in the class?

MrDublin · 10-14-2009, 07:33 AM

I think I'm the only one.

I wouldn't mind seeing an increase in track width, but I am fine with whatever the club decides. I'll keep driving my TLT mini either way.

JohnRobHolmes · 10-14-2009, 07:52 AM

I would like all three to pass. Just because the max length is 9" doesn't mean you have to run it. The increase in track width should accompany the wb. If you are going to increase the voltage, just go ahead and get rid of voltage constraints all together for simplicity. If you keep your wheelspeed the same, a rig will run cooler on 3s than 2s.
