I see us racing our own class within a nitro club once the numbers pick up because I think we have a lot in common with nitros so should race alongside them but maybe not in the same race if we have the numbers and maybe in a modified format like 3x10minute mains and 10 minute qualifiers. I've said it before that the main should be a multiple of the qualifier or very close so there's no advantage to owning lighter qualifying batteries. This will keep the cost down for self sponsored drivers so if the finals are infact longer, we can mandate a minimum pitstop requirement or do the 3x10 main format.
+1. One of the best things about elec 1/8th is not needed a pit person. I also say 10 min max on mains. 15 min on a 4S 5000 is iffy. My setup won't quite make it, I hit LVC around 14 min, so I have to go up to a larger, heavier, more expensive battery. Keep the cost of batteries down and run 10 min. I dont agree with triple A mains, unless its a major race. Again, keep the cost down, where a racer only needs 1 battery to race all day. I also agree with the ROAR rule of 7 min qualifiers. Most of the outdoor racing around here in the summer runs into the evening. A 7 min elec qualifier is the same length as a 5 min nitro qual + engine warmup time. No reason to drag out electric qualifiers to 10 min, take forever to finish a round of quals, and add extra tire wear.

on the length of races. if some of you guys have gotten together and like to run 15 minutes then by all means go for it.
my point is i dont want the cars desined for long mains and especially not swappping packs during the race. making a quick change system will be less reliable than firmly securing them down with plenty of time before the race starts. plus you wont need a pitguy and wont be worried if he can get your car done fast and right without messing up any wires ect.
for the guys that have been running 15 minute mains, look back at the last half dozen races you have run. i will bet that the margin between the winner and 5th place is 3+ laps most of the time let alone what the spread between first and 10th is.
for larger races all you need to do is follow the common tripple a mains and go 10 minutes each. for local races 10 minutes is plenty of time to get things sorted out without the field being seperated by several laps.

Why not make a single sized box, that several batteries can fit in? That way, when you charge your packs between races, you'll be able to see any damage, i.e. puffing. A hard case does not puff, so the results could be a big surprise. Also, as I said before, you can choose the pack that best suits your racing environment. That would allow for a tuning option not available in a strict list of approved hard case packs. It would have the protection/standardization ROAR wants, with the versatility racers need.

All of the local tracks in my area run 15 or 20 min mains combined with nitros. I really like that format.
Until the class expands, that's about all I can race with my rigs. It may never get to a point locally where we CAN race all electric. Maybe there should be two classes, mixed and 100% electric... Or we can just "Wing it" like most clubs.

+1, I run a 5s soft pack with low KV 1515 2.5d, custom made battery tray from rcmonster, I didn't choose this setup for speed as much as long run times, I'm not about to go out and buy a new motor and battery because roar decided to make some rules after the fact, I run a strr and just thought 5s would be better for truggys.

Something like a Cell Phone battery! See, with my idea of a standard battery box, you can put ANY lipo inside, and attach its leads to the box's connectors. Velcro the body, and snap in the batteries, different, but very cool pit stop. Maybe even hinge the side of the body that the battery is on. You could just rip it open and swap packs.

Not to mention that the guy that is leading at the 5, 7, 10 minute mark is going to win 99% of the time. One of our tracks tried longer mains for 1/10th electric truck. Just over the 6 minute mark only half the trucks were left. The guy leading at 6 minutes just got that much farther away in the next 4 minutes.

I unlike so many of you, do not have a 1/8 electric. I have always been a ST and MT guy, most of the time electric. I stepped over to nitro for a bit to see what i was missing, I learned a lot. But , i learned most that i missed electric. I ran buggy, truggy, MT and ST. I also converted to brushless from brushed at this time, made the return easier.

Here's my take on the class.

Why do you need an hour to determine the winner? I like the idea of three 10 minute mains.

Why use a hard case when it traps heat? If you are running on the fringe of the packs capabilities, you will ruin it with the trapped heat. I am talking about the newb buying a 3200 20c pack used to run on a 3.5 setup, or worse, on a 7700 mamba setup

Whats wrong with a 10s setup? Its more efficient, less amp hungry. I have a rc10 GT converted to electric running a 5s 2500 25c pack and a 1200kv motor. I plan to build a MT or truggy setup for a 10s 2500 pack and a 1000kv motor and see if it works as well.

And the biggest question, Why you guys bugging on what either Roar or RC Pro are doing? Let them regulate whatever and however they want, let participation be the mode for change. IE lack of it, if you don't like the rules

I have been playing with lipo's for two years (all soft) and never had one single incident, I have over 10 different packs, from Maxamps to flightpower to hyperion

If you can change your battery in around 40 seconds, thats equal to about 4 or 5 nirto pit stops in a 30 minute main.
also.. there is a finite amount of "speed" a track or chassis can handle.
Electric racers (not bashers) will do the math to figure out what battery/motor combo works best. Similar to nitro, somewhere around 25, 38,000 rpm.
I run Losi 1700kv on 4s w/ 8 2.0 and it feels awesome.

Why does everyone think 1/8E's need to run 20-30 min mains? If you want that run nitro! Fast change pits stops with lipo why??? I understand 4-5-6s thing but why do we need to run such long races? 5 qual and 10-15min mains are good. If you can run a 4s 2200kv for 15 min or a 6s 1300kv cool but at some point there needs to be a class.

do you guys run 1/10 4wd stock and mod together? 15 min main for both? NO!Can you run 7.4 or 11.1 in a 1/10 car in mod class? NO!

So why would we run 4s with a 6s? Do we have class for each battery count? No! that wouldn't work.
I understand alot of the guys that were running 8E's with nitro cars because there were no other electric cars to run with but we need rules to run electric with electric.

min weight: is cool what ever it is to me.
max weight: stupid!
cell count: NEED TO BE SAME!
motors? need rules there also
hardcase or soft? Hardcase for safety only (harder to poke hole threw hardcase than soft) hole = FIRE!!!

While many of you do not want rules to be imposed on electric 1/8th now, you have to realize that if electric 1/8th is to make the next step and get it's own national, you need rules.

You may hate the rules, but they are essential.

Many electric racers hate 17.5 stock, but they still go with it because it is the rule. Electric 1/8th has to accept rules at some point(except stupid weight limits).

15 minutes mains are fun 20 minute mains are funner. I have even more fun when I beat the nitros, although this week I came in second with my e-mugen6. Last week (revelation both weeks, I won) I am moving up to the next class this week, There are 4 classes beg,novice,amatuer and expert. These are some of the best drivers in the nation, great competition and ALLOT of interest in the e cars is picking up. I was the only electric out 70 racers this past week, usually there is 100 entries for a club race with 2-3 electrics. I am glad rev lets me run with the nitros and promote the e cars.

20 minute mains are not a problem with a 5s 5000mah battery for club racing....I am having a ball with the electric green machine!

Rules are needed yes, but they need to be realistic to what is available.

I ran it as a Nitro, Money has been tight this year and the electric conversion will be slow. Personally i wish my ST and MT classes were more popular, Truggy is fun but its too easy, I get bored running them. 1/8 buggy if too fast for my reactions
