Best Chassis, etc for a e-revo racer
 

I am building a brushless revo for racing
what is the better option (considering weight, strength and lowest cg)

1. A gorillamaxx e-revo carbon fiber chassis

Or

2. A vantage Carbon converted (has anyone converted that chassis yet?)
i'm thinking it could possibly have lower cg



thanks for any advice or help. I just wanna stomp the nitro guys, right now they are laughin at me and my brushless rc18t. So thats gonna stop

well you can use the stock Revo chasis, so the Vantage one should also work, since it is the same. you know?

The only disadvantage to the CF one is that chassis modifications are somewhat limited. I bent a couple of pieces as part of my design, which you can't do with CF. The best you can do there is cut parts off and bolt something else on if something custom is needed.

If you plan to go with the CF one, I'd pick up a stock aluminum one on eBay cheaply to experiment with. Once you have the design done, then just swap everything over to the CF chassis. Beats cutting up an expensive CF chassis and then deciding you shouldn't have done that.

Or, just go with the G2R...

EDIT Oh, almost forgot: Welcome to the forums! :)

or just screw on pieces of aluminum for the bent parts?

Yeah, but if he wants a nice clean look, that won't look as nice as one uniform piece...

true. but it would work. (any one know where i can get some cheap 1/8 thick aluminum?)

Check Ebay:

If eBay doesn't have the size and/or grade you want, onlinemetals.com has a nice selection, but not necessarily cheap. If you have something like a HomeDepot/Menards/Lowe's around, they usually have a limited supply of basic aluminum pieces. It's not the best quality though; it bends easily, but it's easy to work with.

Yea - You could also check metalxpress - but if i remember correctly - onlinemetals has 1/8 sheet but only 12" wide - so you would probably have to cut it to size - and xpress dont have anything that size - only .9 thick i think - good luck in your search...

Brian, good idea on the buying a rough draft from ebay, thats what i'll do if i go with the vantage. I was also wondering if the vantage(with correct mods to e-conversion) has a lower center of gravity than the G2R Carbon Fiber.
I wonder which one is lighter

if you do it right, the stock chasis has a lower center of gravity over the gorilla maxx one.

there probally around the same wieght, stock revo to GM. but vantage to GM probally the vantage one.

The g2r has got the batteries mounted real low, and weights next to nothing.

The vantage chassis is maybe lighter, but you need to make a batterietray which would make it most likely heavier than the g2r.

Weight isn't all. The lighter is not 'the better' for racing you don't want your truck to be too light, you'll get pushed around quite easy. A low CG however would help with the handling. With the low possition of the batteries on the g2r you can't go wrong.

This forum is sweet, great advice just minutes away. THANKS TO ALL OF U

Now i'm swaying to the g2r. I think it has a longer wheelbase than the 3.3 vantage? Does either have adjustments the other is not capable of?

The wheelbase is about the same. you have got the ability to fit in the slipperential (a diff with a slipper) which will be available on a short term.

For the settings;

You have got more freedom of assembling IMO, less hassle and a perfect electric bolt on/drop in.

Glad you like the forum!

Stick around to inhale the nice atmosphere!

hhmmmm haaaaaaa
yes i assume you were refering to the g2r

Yes, I was.

Could some explain to me how the stock chassis can have a lower center of gravity or lower battery mounts than a g2r. The batts set almost as low as the skids. If any lower that will bottom out first.

Actually they are identical in wheelbase, I have both. For handling, you can't beat a G2R, it out corners everything i have ever raced against and comes close to running with buggies. Everybody i let drive it are impressed, some of them are hardcore nitro and revo owners

The stock chassis are great for bashing, acceptable for racing - it flips on occurance though... as for the g2r, its an all out racing chassis, even on high grip surfaces i had problems trying to flip it over. For racing, g2r all the way, for bashing stockers work great. :028:

I can't see how, the batteries are flat and lower than any conversion other than Starscream's (lower plate under the trans)

FWIW: The only time I flip (using the stock chassis) is if turning on a high traction surface like grass. On the track, only a rut in the track on a turn will flip it. The batteries aren't exactly low, but the motor, batteries, tranny are all on the same plane. IIRC, the tranny is the highest "heavy" item on the truck. I'm very happy with using the stock chassis.

ill have to try mine out, to get the lowest COG out of my stock chasis.

Ya crazy, I do believe my EVO had the lowest CG using the stock chassis but it definelty wasn't the lightest. Its 2yrs old this month :018:. Boy time flies

I believe the EVO weighed around 12.5 pounds with 18 GP3300's. It was a great racer for its time and was very entertaining to watch the nitro trucks bounce off of it like flies during a race :005: I was able to win several races with this truck.

However, I now own 2 G2R's and would say that if you're going to build a truck for hard core racing, there's nothing better than the G2R. It's light weight, has a low CG and is very durable. My G2R weigh's ~9 pounds with 6S lipo, which is a decent racing weight. If you have the money, go with the G2R.

The Gorillamaxx E-Revo conversion package is fantastic. I'd vote for that.

@starscream;

Yeah, you need a little of mass in races.. I hear you.. Too light isn't too good either. makes the truck handle less predictable, and you'll be pushed around easy..

I never implied that the stock chassis was a bad setup, I was answering Leroy's question about how the stock chassis could have lower center of gravity. Matter of fact i like the stocker setups, but i am a racer and lazy so i waited for Gorilla to do it for me:p :cool: .

On the G2R, i can run in almost anything but concrete and blacktop, high G cornering is a no-no for those. I can out corner truggies with mine

Yeah my G2R will be 1 year old the 22nd of this month (not sure but think i got the first one out of RC-Monster), I agree about how time flies.

I have another Revo conversion chassis, much lower CG than the Gorilla or stock. Basically lipo only though, I am sure you can fit nicds in there but I dont feel like wasting the time in making it work for them myself. I will post up some pictures in the near futute if anyone is interested. Currently running 5s/ big maxximum/ mamba max in it with excellent results. Another good thing is it has a center diff. :eek:

Yes! pics would be great!...

Bye:018:

Welcome to the forums Bomb-Proof!

thanks guys, been a while. :030:

Heres a bad picture of it partially assembled...

Nice, any way you'd have the Bomb proof LSP chassis, id pay a good bit for it! LMK.

ya, I have a all carbon fiber version for the LSP. email me at racegrafix@aol.com :028:

Nice chassis. Where do the batteries sit?

Youve got mail! :)

oposite side of the motor. There is an upper stiffening plate missing in the picture, the battery mounts under it, covers the gears and gives plenty of room for electronics.

What ESC are you using with the "Big Maxx"?

Brian jeremy showed me some pics the other night. It looks really good,.

Is that a one-off or is it scheduled for production? Do you have any pics or vids of it in action?
