Suggested Electric 1/8th section rules

[wallot]

high capacity batteries are still just too heavy for racing. it makes a huge difference in handling when i run 3300mah vs. 5000mah packs (almost 200grams difference).

more shorter mains is the way to go till batteries can keep up.

I wrote it as guidelines for clubs/ the national organisation in the UK, where 1/8 electric isn't popular yet, and when a club is faced with electrics, they may do different things. I tried to write this in advance of widespread electrics racing, so that everyone has the same set of rules. Therefore for an electric racer who goes around different tracks, they would always experience the same rules.

Many UK clubs will be unfamiliar with the format of 1/8 electric. That's the only reason I put lots of recommendations and suggestions in there.

I wasn't too sure about the length of the mains. I was thinking, well, the norm in America is 10 minutes, but it just seems a little short to me (I race 20 minute finals, so it is of course a normative statement). I thought that for 15 minutes, you could use a 4S 5000, or a 5S 4000 or a 6S 3300. All of these are common size batteries (apart from the 5S, but there are many capacities just around that), and it keeps the spirit of 1/8 off-road, where it is a bit of endurance racing thrown in.

Obviously though, I kept it open for the club to decide - minimum 8 minutes.

I see. So you and Neil are the only ones over there who run electric?

Obviously there are others too , but I reckon there are less than 50 brushless conversions that are raced in England. Spread between all the different clubs, and there aren't many at each club.

On rule number 4 you may want to add that 3rd channel mixing is ok (I think most 1/8th scale rules say only 2 channels may be used) for those running mechanical brakes.

You must be using 6s to get away w/ a 3300 pack...

My truggy weight is perfect iMO w/ the hyperion 4s vx 6500 packs, the packs around ~685oz, and they give me a little more run time than the 5s 5000packs that I used last season racing. Changed motor from the 2.5d to the 1y as well for this next year to keep a bette rpm range. The 4s 9k packs are not as highly rated as the hyperions so to be honest the weight difference is marginal (120oz more about). The truck feels a little fat on the track with the 9k's but to save a battery swap for me it's well worth the handling differences as I'd loose more time w/ a battery swap.

14.8v * 6500 = 96200
18.5v * 5000 = 92500
14.8v * 9000 = 133200
22.2v * 3300 = 73260
22.2v * 5000 = 111000

your 3300 pack wouldn'd last me long enough for anything other than qualifiers since I race w/ nitro's in longer a-mains 99% of the time. Id guess that 6s 5k pack was nearly 100oz or more bigger than my 6500 packs as well. Nice thing is for the long amains w/ my 9k packs not only am I getting more run time than a 6s 5k pack but the weight is about the same.
