What are we doing this year for the endurance races? I was figuring that we were going to run the same chasses as last year (the JK chassis where the motor sits on top of the chassis), JK Retro Hawk motors, MySeries GTP legal bodies, and minimum weight of 101 grams. Does any of the directors want to comment? or racers?

I think that the only change we discussed was to have a weight limit this year. I'll check my notes when I get home.  That would mean the same chassis (Cheetah 21), same JK Hawk Retro motor, and using a My Series-legal GTP body.

 

I know that it was brought up to use a totally stock chassis --- no cutting on the motor mount for example.  My personal opinion is that the smoke is already out of the bottle since you almost had to cut on the chassis back in 2013 when we used the Parma S16D motor.

Actually, I would like to suggest (since these are endurance races) that we run IRRA legal GT Coupe bodies. Just like the ones we race at JAX when we race the "flexi" retro cars.  Allow either the 007 or 010 thou bodies. I think that this would be very cool. Most of us have these bodies. Rollin: what do you think?

Since the body mounting holes are higher on the C21 pans versus the C11 pans, we will all have to re-pin the GTP bodies. I would rather buy a separate body dedicated for the C21 chassis.

Actually, we could make the Parma Lola T70 the spec body.

Rollin, for the minimum weight matter, I think that you mentioned 101 grams in an email several months back.

Marcus was the original author of the weight rule.

 

I like the idea of using the GT Coupe bodies.  I'd like to hear from the masses regarding a spec body.

Thanks Rollin; I am thinking that it would be cool to run GT Coupe bodies. Thanks for listening.

 

We could specify any IRRA legal GT Coupe body. That way we could race a Chaparral 2D or 2F, Ford GT40 Mk4, Lola T70, Mirage, etc. 

There is a nice listing on the IRRA rules site.

I like the weight rule. Especially since there are a few different lighter pans then the orginal pans that can fit on the C21 and might not be noticed.

I think coupes would be cool and a nice change-up.

I think can am or maybe the jk touring car body's would be cool like the Aston Martin,corvette,etc. or maybe a trans am body like Camaros,Amc javelins,mustangs,Etc. that way it could spice it up a bit with body's we don't normally run on flexi chassis

I like Doc's idea on this.   GT coupes would be a welcome change and make for some great looking cars.

If we go with the GT Coupe body rule, lets make it easy on whats legal or not legal. Simply say IRRA legal GT Coupe bodies only. These bodies must be 0.010" thick when manufactured. No tape allowed to get an .007" body up to spec. And the max height of the rear of the body is 1 3/8". You are allowed to add a clear 1/2" spoiler attached on the back or from underneath. The 1/2" is measured from the rear of the body work.

I vote for no cutting on the chassis.  101 gram rule - yes.  If we get rid of the downforce body, how bout giving my team a 10 lap handicap? :laugh2:

I'm not sure I'll be able to make any races (but I will if possible) but I would vote to use the IRRA GT Coupe body rules.  The IRRA rules are in place and have been proven to "work", no reason to reinvent the wheel.  I would also vote for the minimum weight (101 grams?) rule, no reason to get into a "lightweight war", it will also make the cars a bit more durable.  Just my $.02 FWIW.

Charlie: the only cutting on the chassis was limited to the motor mounting plate. That must be grand fathered in because we all did it already. However, the only trimming that was allowed was to get the gear ratio and to fit the Parma 16D.  If a chassis had removed more than was necessary, then it is illegal.

 

Jay: I love your two cents worth; I hope we go that route.  Nearly everybody in the MySeries has been exposed to the IRRA GT Coupe body rules or have actually used the rules each month in the GRRR retro racing.

Another rule: for the endurance racing in the past, we had allowed the motor to be soldered in. Soldering in the motor is much more secure.

Soldering the motor is over rated on the C21 - we run them every week at P-1, they don't need the solder to hold up.  Use the 2 different screws and you're fine, machined thread shiny screw goes in the hole top/forward on the installed motor.  Our weekly B Main proves solder is not needed  :wacko2:  :sarcastic_hand:

 

Grandfather a cut chassis for a time when a different motor was spec??  that doesn't make sense, new chassis is not prohibitively expensive.

Charlie, some guys only use this for enduro racing. Not everyone runs this chassis on a weekly basis since it's not a My Series regular class. Just grandfather in the previous minor motor box adjustments.Guys like me would balk at running if we had to buy another chassis that is not regularly used.

Charlie, you are my friend and I love helping you out with advice. You are a good up and coming racer.

But I would never run any race if I could not solder my motor in.

I'm not knocking the racing program that y'all run at P1. I hope it keeps going strong. Just not my or many other racers cup of tea.
Test, test, test and go test some more.

Let's recap ...

 

Chassis - Cheetah 21 chassis - okay to open up motor bracket for gear mesh.  Nothing extreme.  No parts swapping.  Okay to solder the motor in.

 

Body - IRRA-legal GT Coupe bodies.  .010 Thickness without tape.  IRRA body height.  (Perhaps even a spec body --- JK Lola T70??)

 

Motor - JK Hawk Retro

 

Weight - 101Grams

 

 

Anything else??

Rollin: I like your recap.  We could go with a spec body. Example of some:

1) JK Lola T70 coupe p/n 71902B, or

2) Parma Lola T70 coupe p/n 1039B

These bodies should be available thru the normal distributor system.

I've been running the C-21 chassis for a long time and never had a motor slip (even one time when I forgot to tighten one of the screws).

I'm wondering if soldering the motor helps the car handle better.

I know if you solder the motor you can set it's angle flatter so it's closer to a sidewinder and then tighten the screws (mostly for show maybe).

I wonder if any rules state that the motor has to be flush against the motor bracket.

If so, so many of us hadn't already opened up the motor bracket when we were running the Parma S16D to get a gear mesh, then you might convince me to stay totally stock on the chassis.

 

I own two of these chassis .... one to race and one to loan .... and they only get used at this event so I'm not crazy about buying a new chassis to run this class.

Rollin: I am with you on this matter. Run the C21 chassis that we have been running even though the motor mounting plate was slightly modified for a gear ratio. However, I know there are some chasses that had the top 1/4 to 1/2 or the back 1/4 of the motor mounting plate removed. These chassis are illegal because in the beginning when we did this, it was stated only remove what was absolutely needed to be removed. But as racers go, some cut off the top half of the bracket. We must make it clear before the first race, if too much of the bracket was cut away, then it is illegal. Buy a new one.

How are teams chosen?  

 

Are teams picked with captains, or do we go find a teammate?
