Columbus OH 1/8th Brushless Race

[Papa]

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.

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