e-revo chassis
 

I am tryign to find an after marcket E-rvo chassis i have tryed the Kersaw chassis and all it did was bend and the stock chassis i have also heard about a G3R chassis but i can't find one any where is there any other chassis i could try?

I was also thinking about trying to run a vantage CF chassis but i wasn't sure what battery boxes would work?

The Gorillamax G4! I've been tempted to get one of these for awhile now.

Check it out.

Sadly that G4 is for a tmaxx, there is not a gorillamax chassis being made for the revo right now

I run a Nitro Revo 3.3 with Vantage Carbon-Fiber chassis converted to brushless using Mike's RCM motor-mount and the stock nitro transmission locked into 2nd gear with all of the 1st gear parts removed. I custom-built a carbon-fiber battery-tray that mounts on the right side of the truck in the exact same place that the Tekno RC battery-tray mounts when using the Tekno BL conversion. I also custom-made carbon-fiber ESC tray, Receiver tray, motor-mount brace, motor-mount support, and accessory tray (nothing mounted on it yet).

With the motor on one side and the battery on the other side, the truck is perfectly balanced, handles beautifully, and is uber-durable!

The G2R and G3R are made specifically for the Revo, they are just hard to find...and if you do find one, it is crazy-expensive!

Yep, that is what I ment lol, There used to be but they are no longer being made

And [here] are some pics with the body on...

Whats with all the zipties on the motor?

Ooops Sorry. My bad. :whistle:

yo chad, would you consider making another esc mount like the one you have there and sell them to me? It would really help me with my build. LMK

Also, what brand pinion is that?

I am deployed at the moment so trying to build anything out of CF on my own is out for the next 12-14 months i was hoping that there was one i could buy. I guess i will try the push rod mod i seen on mister crash's thread and see where that gets me

I had an incident when I first built the truck where I didn't set the pinion back far enough and when the motor spooled up, there was just enough rotor-float to allow the pinion to come forward enough to get into the slipper, which torqued the motor forward and to the side, bending the RCM motor-mount (which Mike replaced for free, by the way). I now use zip-ties to hold the motor tightly against the rear cradle and brace.

that revo is very nice but i am afraid that i don't have the time to build something like that

Sure! The pinion is actually a crappy Novak pinion. I usually run Mike's RCM pinions, but I had to switch spur-gears and the only pinion I had that was the right size for the new spur was one of my old Novak pinions. trust me, don't buy Novak pinions, they are horrible...they are not truly round, the teeth are not profiled correctly, they are cast instead of machined.

Cool, Thanks! I'm doing a deal with a forum member to sell my 2650kv motor and get the 2200kv like you recommended. Then I'm going to lock my tranny in 2nd, move the ESC to a lower cg position (with your generous help), and change out my motor mount for one that can accomadate regualar pinions with the longer motor. Im trying to decide whether to go with a the new style tekno black motor mount or Mike's. Miek's is $5 more, and the Tekno one will match my balck chassis. Still not decided on which one though as durablility is more important the looks to me. PM me about the ESc mount.

Go with Mike's mount, there is no other choice...the Tekno mount requires either the Electri-Clutch or Long-Shank Pinions, and it just isn't as good as Mike's...PERIOD!

Oh, which piece do you want me to make as your ESC mount?

Cool, Mikes it is then! I would like the carbon fiber piece on the side of the chassis where the mechanical brake servo is on the nitro version, like the one in your pics. It will be for a MMM ESC, maybe you could even put in holes for the plastic mount from the ERBE.

Oh, the new tekno mount doesn't need the long shank pinions, but I think i will go with Mike's anyways.

One more Q. Do you think i should go with the standard or wide 2nd gear. Standard with 36T spur, 17T pinion is geared for about 41 m.p.h., and wide with the same spur and pinion is about 44 m.p.h. Tjhat gearing should be just fine right? No over heating problems on 4s?

And on a third thought (LOL), I see you made a cf chassis stiffener that attaches with the motor mount. Have you experienced hotter temps because the motor mount isn't acting as as much of a heatsink now? It looks real good though.

Good call on Mike's Revo motor-mount, it is the best!

I recommend using standard-ratio gears, because it's easier to gear above or below.

No, I have not experienced any higher temps due to my CF brace between the motor and the motor-mount.

Also, Yea, I can create the ESC mount in the place you want, and have mounting holes for the TRX MMM Mount.

what exactly do you mean by it's easier to gear above or below? would you think it would be better to have Std gears, 36T spur, 18 pinion geared for 43 m.p.h. or wide gears, 36T spur, 17t pinion for estimated 44 m.p.h.?

If you have close-ratio gears, you don't have as much room to gear up...if you have wide-ratio gears, you don't have as much room to gear down...if you have standard-ratio gears, you have much more room to gear up or gear down, and aren't limited by an already high or low ratio.

I gear for 40mph, but as long as you have the right battery(s), you can gear for whatever speed you want. For me, 40mph is perfect for the area I run in. If you want to gear higher than 40mph, you will need 150A or higher batteries.

My Turnigy 5000mah 4s 40c batts pack at least 200A, so I'm not worried there. For now, I think I'll go with the standard gear and the 18T pinion, and if it's too much I'll get the 17T which will bring it down to about 40 m.p.h. And let me know when you get the ESc mount done, there is no rush, but just so i know when to expect it. Thanks!

Yea, I run either a Turnigy 40C 4S 5000mAh (200A) pack or a pair of Zippy 30C 4S 2650mAh packs in parallel (4S @ 5300mAh & 159A) in my Revo.

And one thing that you said that I agree with completely. a lot of people complain that the conversions are unbalanced, but mine is near perfect (with the slightly heavier 2200kv motor I believe it will be spot on) as is yours. My center balance point is basically right under the transmission, and this truck rights itself in almost every situation.

Oh yea! Using a single digital scale under each tire at a time, my truck is balanced front to back and left to right within just a few grams! I am going to buy 3 more identical scales so I can get a truly accurate balance measurement.

Nice. Man, I can't wait to get all of this stuff together!

ok now i have a new question the ground out here is covered in 1.5 to 2 inch gravel is there a set up that will help on this stuff, so far i have started to run
badlands tires
RPM front and rear A-arms
alu shock mounts
a center one way drive shaft (to stop wheelys)

i have also added the push rods to stiffen the rear bulk head. I haven't broke anything but bodies, but my friend can turn alot sharper at speed than i can just trying to figure it out

What rockers are you running? What color springs are you running? What weight oil are you running? DO you have anti-swaybars?

ok i am running 45weight oil in the shocks, p2 rockers in the back. LT rockers in the front, and tekno swaybars

the biggest problem is while turning even at low speeds the inside wheels lift off the ground. So i end up almost stopping for corners.

Well, you need to switch to the same rockers (I recommend P1) front and rear, the middle-weight Tekno swaybar bars, 55wt oil in the front, 60wt oil in the rear, and Traxxas VDP piston set (off-road position) in all four shocks.

thanks i will try all that out it will take while for the VDP piston set but thats just how it goes

Yes, no mixing rockers. And as Chad said, thicker oil and the VDP kit will help too.

Oh and Chad, any updates on the ESC plate?

MedicineMan - Are you in WA DC, or WA State?

Took mine off, have the new template drawn with the holes for the TRX MMM hold-down located, I just have to cut it out and smooth it up!

Cool, thanks! As I said before, there's no hurry. But glad to know it's coming along.

I live in WA state but i am in afghanistan right now with the 1-503rd
