New ROAR Rules

[RC51]

Well, race fans, it looks as if the new ROAR President and Exec are making shifts in the market. Here is what she just posted on RCTech tonight after the 2008 meeting:

Yes, 27T and 17.5 is the stock class of racing in ROAR competition and ... This will slow down the stock class of racing as it needs to be and maintain the stock brushed motor use at most events, especially off road, we are assuming.

19T and 10.5 is the Super Stock class. (formerly called 19T class) We recommend local programs stick with what they are doing that is working for their integration of brushed and brushless motor racing. In 2009, 13.5 will be the Super Stock class.

I'm sure there are criticisms, questions and probably even a little disappointment out there. We took the future of ROAR racing, our membership and our affliates into consideration. I'm sure you all can understand the position the Excom was placed in and the decisions were not made hastily. This thread was extremely insightful and educational for me and I thank each of you.

LIPO 7.4V BATTERIES ARE APPROVED IN ALL 6 CELL SUB-C 7.2V CLASSES

really lipo's are approved for 6 cells.Maybe i will run eletric this summer.

[BigDawg]

brushless it is! im sure glad both my esc's are brushed or brushless,does it say weather the lipos have to be hard cased?

[RC51]

Well, Dawn Sanchez (ROAR Prez) says that there are 9 pages of specifications and rule updates to follow! My guess is that yes, it will be hard cased based on the various threads and input from all over. Of course, IROCC's Exec decisions may be different for motors and batteries, but who knows. It will be interesting to see what happens with 1/12, too! I couldn't find anything on that one.

New ROAR Lipo rules http://www.rctech.net/forum/showthread.php?p=4081220#post4081220

[RC51]

BTW, very interesting teching considerations for the LiPo and the madatory use of a LiPo Sack for charging. Nice that they have that one down. The other side of the nightmare, though, is teching BL motors at club level racing. I wonder how they will deal with this - interesting times ahead. There are too many variables such as on board programming of the Exc let alone the variables associated with the motor. Wow.

Yep, very interesting stuff.  As Phil says, these are ROAR rules, and although we do usually stay somewhat "in-line" with ROAR, we do not follow their rules to a tee.

We'll be meeting sooner than later to determine our summer (and beyond) rules, and we'll get you this information as soon as we can.  Our rule set will be based on what we think is best for the IROCC club racer.

Personally, I'd be interested to hear from everyone in the club about what they think about these new ROAR rulings.  Everyone looks at things differently, owns different equipment, has a different budget, etc... so it would be interesting to get feedback from everyone.

Does anyone have "actual" experience running a 17.5 brushless system against a 27T brushed system?

How about actual experience running a 10.5 brushless system against a 19T brushed system?

I have a few days of experience seeing both 27t brushed and 17.5t brushless race together.

Although they were similar at the small track I was at racing at the, 17.5t had more "rip". Every straightaway if there was a 17.5t anywhere near you they could catch you and pass. This was a small "bull-ring" race track in New York.
I think on  a big outdoor track a 17.5 would completely destroy a 27t brushed to the point where they couldnt really race together. That is just speculation based on what I have actually witnessed.

I am not saying I am against brushless. I am in fact pro-brushless.

I vote lipo because of all the problems that we have had with other batteries.  In my opinion, battery is a yearly thing  that you would have to buy and i don't mind buying lipo for this year.  

What I am NOT in for is brushless, as I would have to upgrade my ESCs.  That is not in anyone's racing budget.  Not in my budget anyways.  From what I have read there is a clear advantage of brushless over brushed.  If racing together, us, brushed guys would get destroyed and there is no fun in racing no more.

I'm not sure about a vote, but your point is fairly narrow.

You don't want to go to brushless because you don't want to have to buy a speed controller, but you don't mind going to LiPo since you already have a charger.

What about the people who would need a new charger for the new battery chemistry?

Changing the motor or battery technology to the ones proposed are equally significant.  Both technologies are superior to what we currently use in many ways, and we'll need to change at some point in time.

However, how proven are the lithium chemistry batteries?  I for one have heard many more lithium related horror stories over the years than nickel chemistry horror stories.  Yes, the current crop of lithium batteries are far superior in many ways over the flaming laptop and flaming cellphone era, however so were the NiMH we used just a couple years ago reliability wise.  Once the current R/C trends in battery production shifts into the new chemistry, will we be in the era of flaming carpet knives?

I think that brushless/lipo should be kept in their own class. you cant compare the two its like apples to oranges.

[haddow]

Here is how I see this year's outdoor program to deal with the new rules and the future.

Class 1 - Flagship electric touring class -  stock 27T brushed - up to 7.4 V battery (this will be the last year of stock brushed)(and start battery transition to new technology now as well)

Class 2 - 17.5T Brushless Touring - Next year's flagship class- up to 7.4 Volt batteries.

Class 3 - Pro10 Brushed 19T or real/true brushless equivalent, up to 7.4 volt battery. (Yes mix the motor technology in this class).

Class 4 - Nitro

Next year we would be back to 3 classes, 1 electric touring, 1 electric pan car and 1 nitro. A class to suit each person's RC appetite and deals with upcoming technology we can't ignore.

Hey phil or anyone else

Do you have a link to anywhere that shows this anouncement is official?
It isnt on the ROAR site.
