Default 8ight weight

Whats the running weight of your brushless 8ights? or brushless buggies in general would be fine

Im trying to pick a 6S battery and with a 3300 30C Im at 7lbs, 10oz. With a 3900 25C Im at 7lbs, 13oz. I dont want too much weight to cause a handling problem.

My 8ight is converted from nitro w/ the 2200kV/MMM combo (same as Pete) and a 5S battery - either 4900mAH 5S 20C Rhino (zippy) or 5000maH 5S 25C Flightmax Zippy, both weigh about the same. The 8ight is 7lbs. even, with the battery about 8lb. 4 oz.

I jammed a 6S in there which pushed the weight to almost 9lbs. which I found to be too heavy and significantly affect handling (especially braking). I'm trying to figure out what you've got in there to bring it to 11 lbs. Did you replace all the plastic parts with custom cast iron or something?

with the Losi 5s 4000, mine comes in at a porky 8.25lbs.

What is everyone's suspension setup?
I'm running

Fr Geen/54/40wt
Rr Green/56/25wt .

I think Green is too soft and the #54 at the front isn't damped enough for the porky 8.25lb 8ight.

I'm thinking of going to F/R Black/56/25.. any comments or suggestions?

thanks.

Seems like a no-brainer to me. Why would you want the extra 3lbs?

8lbs 1oz
8ight 1.0 buggy mmm/2200kv combo
jrz9100s servo zippy 4s 5000

I run the mike truhe setup with 28.5w shock oil in the rear and everything else just like the setup sheet.
car feels very good.

dont go stiffer on the springs. it gets way to bouncy. just slow up the dampening in the rear with a bit thicker oil. if you have a tendency to over shoot, flat land or lawn dart your car. you may need some stiffer oil in the front.
with my driving style just some stiffer oil in the rear worked well.
just my thoughts.
I also run 5000 in the center vs 7000 in the truhe setup

LOL. Big typo there. fixed. Thankx.

The 6S 3900 actually touches the 8E body a hair. The 3300 sits below it about a 1/8". Has anyone heard of a lipo catching on fire because of impact in a car?

Nope, in fact, the only time I saw one burn in a car, was due to being left connected for days and over-discharging. I've seen a 3S in a small electric plane crashed and the end of the battery smashed. He STILL flies with it, and it works fine! The fires I've seen, have to do with brain farts, not impacts.

A Few ways to reduce weight

1. Use the kyosho plastic spur -20g over steel
2. Use AE 83mm wheels (they are the lightest I know of @ 33g ea.) -24g over other dish wheels.
3. Shorten your wires (1 foot of 10ga = 1oz) -28g
4. Use a 1512 size neu motor instead of a 1515 -50g
5. Use a soft case lipo instead of a hardcase -120g

Thats more than 1/2 lb of weight savings right there.

The AE wheels are 24g lighter per wheel? or for a set of 4?
Link?
I use panter rims. They are 35g each.
I got the losi plastic spur.
My 10 guage is pretty long.
4 & 5 already done.

I was referring to the weight savings of an entire set of wheels, I've had wheels they weigh up to 42g each. TBH, I have no idea how much losi wheels weigh.
