Columbus OH 1/8th Brushless Race

[lxmuff]

I forgot to post this here too. There are some folks who might want to go that also frequent this site. I'm trying to convince glassdoctor to make the trip.


Here is a post from Tony Screws:


"I sent an email to Keith (Big Dog) and asked about adding a provisional 1/8th Brushless/LiPo class at the electric race. Keith said he would add the provisional class if we can get enough guys committed to coming out. Personally, I will definitely make the trip out for the electric race to run my brushless MBX5R (as soon as I get it back from Stephen Bess at R/C Car.....if he gives it back ....LOL ).

The race flyer has already been printed and is running in the magazines already so the only advertisement will be amongst ourselves online. They will only be able to add one class since the schedule will be very tight already so that class will be 1/8th scale buggy. I know many of the factory teams are interested in this class and many will have drivers out for the Nitro race or both. So I'm going to see if I can spark some interest over there in the factory camps.

If anyone is interested, please drop me an email at tony@tony1034.com

Once I get enough guys committed, I will gather all the registration info from everyone and get it to Keith. I'm not sure when the registration will open for both races (if it's not open already), but once we have enough guys committed we'll be starting the registration process early to show our committment to the guys at CRCRC. Plus I don't think anyone wants to hike many hours to go to a race and find out that only half the guys showed up and now you can't race (I'm in NJ and it's a 7 hour trip). Keith will be handling the registration info funneled through me personally since this class is not on the flyer.

I'm really looking forward to running my car when I get it back from the magazine. But I'm also looking forward to getting some good exposure at a very well know large event like the CRCRC race. So lets make this happen boys (and girls if there are any running these conversions ). If I can get enough interest soon, I'll also contact the magazine to see if they're interested in coverage of the class.

Thanks and best regards,
Tony P.

The minimum is met to have the event. Others may still participate, just follow the below instructions.






Have them send an e-mail to president@crcrc.com and in the subject line say "1/8 scale electric entry" with class, freq 1 and freq 2, shirt size, and transponder #, then send a payment through PayPal using the same e-mail address as the account name( president@crcrc.com ). Or fill out an entry form and mark it as 1/8 scale electric then send it to the P.O. Box on the form.



Please be advised that they are requiring the use of a LiPo sack for safety reasons for the electric week. They picked up a sponsorship from http://www.liposack.com/ for this event and they are offering a great discount on the LiPo sacks. The info on getting the discount has been posted on the rctech.net forum and I’m sure there are a few links on the CRCRC website and the Starting Grid conference. I’ll dig for the sponsorship links and post them this afternoon if anyone can’t find it.

So the 1/8 Brushless would be held on the electric race days? Are they going to let us practice on the practice days with all of the little fragile 1/10 electrics? I cant imagine a championship quality 1/10 electric being to happy having to run on the same track as a 1/8.

But sounds great. I doubt I could make it, but I'm really glad to see you working hard to promote the class! Outstanding job!

[lxmuff]

It will be on the electric weekend. Not much has been talked about the practice. On the Friday, it will be a controlled practice to keep them seperated but earlier has not been discussed.

I'm sure a lot of them that have never seen these run will want to take the wheel.

There will be a number of 1/8 from our local tracks attending this race. Typically the classes are split for practice, with time on the stand being called by the RD. I've been to the last three years of this event. I will be there for the Nitro Event the following week. Truly a great program with top drivers from around the country in attendance. Well worth the travel and expense, and a huge opportunity to get the 1/8 electric class off the ground on a national level.

Here are the rules for the ELECTRIC 1/8th buggy class at CRCRC.

I think the voltage allowed should be changed. Some of us like to use 6S, 8S, 10S and even 12S. This could open doors to a lot of things.

That's the first thing I thought of when I saw that. Folks are still treating BL motors as if they are brushed motors. I run 5S, so I'd be out. No mention of KV limits, which have just as big of an impact. If they want to put some limits that really mean something, they should do it on a watt basis, which would allow for a lot more lattitude, but still keep everyone to the same power level. Aim for a 1,500w limit and call it good.

Also, what's up with limiting to LiPo only? What about folks who want to (shudder) run NiMH, or A123's? I'd want to run A123's on mine (albeit 6S) to trim my weight down some for racing.

I can say that it is a start. That's the hardest part. The rules will precipitate discussions (like these) which will hopefully move them in a positive direction.

Point well made sleebus.jones. I didn't make my statement clear, but I like the fact that I consume less AMPs with the higher voltage. I think the watts might be tough to do, as I can use my 6S 2200mAh (25C(55A)Continuous, 30C(66A)Sustain, 50C(110A)Max Bursts) packs that has the potential to put out around 2000W. What would work is to keep the RPMs at bellow 40K and the options for motor will be wide open. I have run my 2200mAh packs for 23 minutes with no problems at all. Good thing about them is the fact they weigh only 193g each.

[sleebus.jones]

Lutach, I am totally and completely with you on the higher voltage. I'd run higher but my ESC's won't take it, and my pocketbook won't take a real HV ESC at the moment!

The reason I suggested watts is because it's a measure of work. RPM just measures speed, and torque is independent of speed. Just keeping the RPMs below 40K doesn't really equalize the playing field. (I realize you already know this but for other folks....) For instance, say someone wants to run a 10S 2300mAh setup. A 14XL will keep the RPMs under 40K, but (assuming A123 cells) that's potentially a 2200w setup. Likewise a person could get a 2S 3800 20C LiPo pack with a 7S motor, stay in the 40K range, but only make 562w.

I too should have been more clear in my response, haha!

What I should have said is that you can have any pack you want, as long as its output doesn't exceed 1500w. That way everyone has the same potential power to work with, and they can choose to go with any setup they want in terms of cell chemistry, cell count, motor type/kv/efficiency level. What would (hopefully) happen is that it would drive the industry to more efficient levels, which helps out the consumer.

In 1/10 scale the 7S works good, but if they go on to 1/8 scale, I'm not too sure if the smaller motor can handle the weight. I'm only saying to keep the RPMs to bellow 40K to let people choose the voltage and the right Kv motor and it might also show people that you can run a cheeper 2200-2500mAh 6S set up and still get over 20 mins. of run time.

[lxmuff]

The idea for now is to get something started (not trouble) for other than the people here on the forums to see what this stuff can do. Giving some rules for this race, to start with, makes it a little more ligitimate, not to cut other people out. I do like the idea that OPEN is OPEN. These things can go faster than anyone can handle. I like the 20 minute A-main too. These can make it on one pack (No Pit Guy).

At our local race two weeks ago we had 13 brushess 1/8th scale buggies and 3 Truggies.

Here is a pic of the BL vehicles on this thread:

[sleebus.jones]

That's an awesome turnout lxmuff. I doubt there is more than one BL buggy in the racing groups I know around town, and it's mine! Hah. Sad, really.

I think the 1/8th scale has died down here somewhat too, and I think its due to the work required in keeping one running. I need to show mine off a bit and maybe I can get something started down here too.

Send a note to Tony to make your recommendations. This is an exhibition class and should be open to all configurations.

I'm not too happy about the votage thing either... some of the guys around my area are thinking of going, but they are most noobs into brushless so they're pretty happy with the 14.8... I myself, don't like it... my lowest setup is 6S.. most everything else is 8-12S... Let's email the guy...
