Lightest Buggy? - Page 3 - RC-Monster Forums

SpEEdyBL · 10:36 PM

As for me, I've done quite a bit to my 8ight in terms of weight reduction. As soon as i replace the mamba monster with the mamba max pro ill be at roar minimum weight with a zippy 5000 mAh 4s pack, which is 3200g.

Hi guys, I don't know if this is accurate but the lightest buggy in my site is OFNA Ultra MBX R2.

That's not it's final running weight though. About 3.5kg would be nearer. For example, the D8 listed weighs 3.4kg, but that is the RTR weight. As a rolling chassis, it'd be nearer 1.9kg.

With current brushless systems, I wouldn't get caught up on weight.. distribution maybe, but not the weight itself. Well I mean you don't want a tank, as you will get more broken parts, but typical setups are zero issues and a few oz. won't make you a winner or a looser w/ brushless power.

Power isn't the issue. The coefficient of friction between the tires and the ground increases as weight decreases, thus higher lateral grip for faster cornering.

you must not race

in racing weight effects everything and there is never a positive to haveing more

I race, took first w/ MT's (e-revo) in the last local pro-series event, took 7th I think in 1/8 e-buggy. Unless your a pro, I'd give you a run for your money or take it :)

I'd agree w/ carpet racing or on-road racing (high grip), but when traction is an issue there is a point where you get too light. If you read what I said with TYPICAL setups (conversion) a few oz will not make a difference... I never said load up and get sick heavy (tank) :) GO back and re-read my statement, I stand by it.

Does a heavier buggy give u a stable advantage? I am converting a x2.

I race a heavy CRT x1 with 6s tons of power n stable. Won many races till now

I've noticed a night and day difference in performance with a 4000 mah 4s pack verses a 5000 mah 4s pack. That is why my next zippy batteries will be a 40c 3000 mah for 10 min mains and 4000 for 15 min mains.

When you decrease weight you also have to change your springs and shock oil, btw. Were not talking about a few ounces of weight. Too many stock conversions are way overweight, half to a full pound over (7.5 to 8lb total).

If so light do u still hv traction?

Indeed you right, less half weight than common 1/8 buggies, that weird.
It stated at 1633gr which much less than D8, but I don't know what parts are not included in MBX kit.

Yes. "U" still "hv" traction.

I'm not trying to derail this thread, but PLEASE SPELL words out and use proper grammer. It makes the lives of us readers much easier, and prevents us from thinking you are a stereo-typical 12 year old. To answer the question intended, yes, my buggy does have more traction with less weight. It's more responsive too.

Lauri · 11.18.2009, 08:28 AM

Go with the 808. It IS light and extremely strong. I've had 10+ races this season all with A-mains (except Euro champs ;)) and NO retirements. Broken so far during the whole season : front antirollbar (how?), rear chassis brace (running electric with a lot of chassis flex) and one diff pinion bearing. That is it!

You can make it even lighter by using some of Xray upgrade alu parts. Going under legal 3200g when running nitro is possible with ease!

Most all buggies are tough as nails.. my 8ight lasted me 1 1/2 seasons before I sold it and at that point I had only broken 1 part, a front hub from a mid air hit w/ another driver. Well it was what came after the mid air hit that broke it.. lol that steel pole jumped right out in front of me! LOL I did have a few shock screws back out, ie the screw that holds down the disc on the shock shaft. Red thread loc fixes that just fine.

PS the guy I sold it to is still driving it :)
