Please clarify what people are proposing for battery/motor rules..
Is it 1s -or- 2s with 21.5???
...and for 17.5???
possibly 13.5 outdoors??? Hmmm..
Oh and....keep the foams!!!
Really helps build the groove on dirty or green tracks for club racing.
Pan cars on rubber tires??? Preposterous!!

Id be perfectly fine with 21.5 being the motor of choice for the LM1/LMPC spec class. I reckon that once we get the numbers for the LM1 class up across the country, you could see a second more open class with a 2S/17.5 powerplant combo follow. (Id give the LMPC class about a year before going that route personally)

Hey guys, I was talking with Brad Palmer aka bp shadow, and we were discussing how this class could maybe be run. We were talking about having diffierent motor and battery configurations and giving everyone a choice on what they wanted to run, but they would all run in the same class or heats, whatever you prefer to call it. You could have guys running 21.5 to guys running 13.5, single cell or 2 cell has not been discussed yet. The one thing that came to question is chassis configurations. A lot of people have old WGT chassis which are pretty much the same as the new lm1 chassis with the exception of the wheel base. What we thought of was that if you are running a wgt car you would probably have to run the courage body from the 103 gt as the wheel base is the same, the speed passion lm1 body has a longer wheel base and will not fit properly on a wgt or 103 wheel base. The biggest thing in the rules would be that you would have to cut the bodies out on the pre scribed lines for the wheel base, this keeps the bodies looking correct and not hacked. What to people think about this?

Running multiple classes of cars would be a lot of fun on large carpet tracks or on asphalt tracks. But probably chaos on smaller tracks. Need the wider lanes for passing at speed. And the lanes would need to treated full width to make it work.
Think open practice at any multiple class nitro race....can get a 'lil crazy.

Thats true if you have the ability to do that, the main think is to keep the body trim line and wheel arches in the proper place for the scale realism.

I agree on the dimensions, I just don't think the chassis should be restricted to F1-style. Also, the tire and rim dimensions should be controlled, but I don't think it's necessary to call out hex drives for the rims. Even F1 cars have two different hex drive sizes (14mm for Tamiya, 12mm for HPI, if I recall correctly), so it's not like there is already a standard.
In any case, it's pretty easy to stretch the wheelbase and fit F1-style hexes to a WGT chassis.

So far in testing with the LM-1 spec kit, 21.5 2S on medium to high grip carpet works well. 17.5 2S is a handful on the same type of track and detracts from good racing. On a long high grip track it would be a decision to run 17.5 2S. 13.5 2s would work on large outdoor venues, something we don't have locally. 13.5 1s WGT is still a rocket in comparison to the 21.5 2S in the same conditions, I'm guessing it's the 250+ gram difference.
*** If SP wanted to corner the market, they could put out the FRP lower chassis plate to accept other front ends: CRC, Associated, Tamiya F103GT, etc. At $20.00 for a replacement, they would essentially own the class.***

I am looking at some of the posts, and I think there is some good dialogue going on. I would caution about allowing too many combinations or trying to adapt this chassis or that. It was posted earlier to honor the wheelbase of the body, and I think that is important. I would allow the TAMIYA 103 GT to run as long as it is fitted with the SpeedPassion wheels and tires. This should be the standard for the class, and there should be a wear limit on the tires. Also I don't think that LeMans should be split into separate classes. To me it makes no sense to have 3 different LeMans groups and only have 2 or 3 cars on track at a time.

And while I don't mind the principle of spec tires/rims, I DO mind when those spec tires/rims cost $60 for a set. That's twice what a set of 1/8 scale nitro foams cost! In this case I think it is best to just specify the min/max diameter and width to encourage some competition in the market.
Yes, there should be a minimum OD for tires, to preserve scale looks.
