Looking for my first rc car. Was looking to get the redcat shredder but I also want to consider resale value to be honest, in case of an upgrade or something else. 
 
I found a traxxas e-revo 1/10 scale local. It comes to RTR without batteries and charger.  
 
Would you buy this? Anything I should check for? 
 
I need something FAST, QUICK and handles very well and will be running almost 100% on grass for my dog to chase. Without overheating. The 1/6 scale from redcat at least offers this due to its sheer size. Not sure if the e-revo can but i saw videos of i blazing down grass. Just curious about this particular model.

Those are cool trucks and depending on the condition and whether it comes with the 2.4ghz or older AM radio will determine it's overall value.


I took a quick look on Ebay and noticed that in the past 3 weeks, rollers (trucks without electronics) sell for $200-$260 plus shipping.  I've seen something similar to what you're describing list for $340 plus shipping and no one bought it.  I saw another one with a Hobbywing ESC sell for $325 (shipping included).

So, I think his truck is worth $250 IF, it's not beat up.  If he didn't bother to clean it up, if the suspension feels gritty or sticks when you compress it, if there's lots of scrapes on the bottom then I'd say that constitutes excessive wear.  Some wear is expected but if it looks like he took a cheese grater to it then I'd start to reconsider the whole thing.

Even if he doesn't have batteries to sell ask if he can put his own batteries in it and drive it to show that the electronics work.  Let him do a demo-drive for you.  From there you can expect to spend about $60-$80 for a pair of some budget 2S LiPo packs and about another $30-$60 for a LiPo charger.  See this link and this one too

5000 / 25C packs are the minimum recommended packs.  Those will supply 125A according to what they're rated.  If you don't mind spending a little more then you can increase the mAh rating, C rating or both depending on your budget.  It's safer to use batteries with higher amp ratings than what the ESC is rated.  Since that ESC is rated 120A, the 2 - 5000 / 25C packs will barely meet the minimum amperage and you should be safe.

When the owner said it can take 6S then you are correct for assuming 2 - 3S packs.  The Revo has 2 battery trays and 9 times out of 10 the ESC's power leads are wired in series.  Therefore, 2 - 3S packs work as 1 - 6S pack.  Just be sure to use identical batteries.  Otherwise 2 - 2S packs will still be very powerful and the truck will be plenty fast.  My Savage can do standing backflips with 4S.  I could only imagine the parts I'd break with 6S.

Thanks man. 


But i appreciate the help. The choice has come down to a slash with a LCG kit (VXL esc and motor) or a redcat shredder. The shredder will have no problem in grass or overheating. But I question its resale value and possible durability.

Id skip on the shredder.
Im a redcat fan, but the shredder has issues and redcat knows it....thats why they are no longer selling them.

Basically, the shedder is a stretched 1/8 scale 8E model. Adding the larger tires and more weight to a 1/8 chassis just doesnt work.

The main issues are the diffs. While some people got diffs that lasted a good long time, others got ones that failled very quickly. Some dont come shimmed well from the factory.

Im getting a earthquake 8e soon (should have it in a week), and Ive owned one before. Having owned one, I cant imagine that a stretched version of this truck will be as durable as I would like.

There is a reason the 1/6 shredder is under $300....and the 1/5 rampage electric is over $500. Big difference and quality and durabliltiy. And when you get to models that scale the parts HAVE to be built thicker, stronger. The parts on the 8e were meant for a model its size. The shedder's share 90% of the same parts but have more weight and size.

It wasnt a bad idea, it just didnt work well.

Too bad the guy was a jerk, a $250 brushless E revo 1/10 is a steal.

Oh man really? Why the earthquake though? Would the shredder be a better pick considering it's cheaper with 1/8 parts? There's a backdraft 8e that is for sale around the same price that I might consider. I honestly cant decide. 

Would you go slash/rustler over the shredder then? the grass im planning on running it on is 3" or so and I'm not sure if its going to overheat. Wondering if i can add fans to address that but not sure..

3inch grass will be hard on most 1/10ths I'd say a 1/8th scale MT is pretty much minimal as to what is needed.


the problem with your logic on it being cheaper for parts cause they are 1/8th high chance is you will be replacing them more. So instead of replacing one $15 part you replace 6 $8 parts in the same time frame (as an example)

I would listen to nitro on that notice he is a redcat dealer, and is saying he would pass on it

Trust me I like being frugal to the point of cheap but sometimes its just worth the little extra so you don't end up with a money pit (I've had a few)

Oh i meant in reference to what he said about getting the aftershock or earthquake 8e. if that's a 1/8 scale, why not get the shredder which is 1/8 but on steroids and cheaper? but i did not know he's a redcat dealer so i take his word for it haha. damn i guess the search continues..

easy answer
more weight = more stress on the parts, and seeing the parts were never built to cope with it so they will fail faster, and more often. If that wasn't the worst of it on top of the chassis weight they slapped bigger, and heavier tires on it so that is more rotational force on the diff, and axles which will cause then to fail more.

I am not in the least a Traxxas fan but even I would have gone for a $250 e-revo if it was in good shape. Not buying it out of spite from a guy who was a jerk is really just shooting yourself in the foot. I mean it sucks he was a jerk but not a reason to not pick up a good deal.

well in this case I'd have not also as if the guy didn't want to answer any questions he could have ended up with a truck that was in poor shape that the guy doctored together just to make it look nice.

also I thought the revo needs 4S minimum if it would run on 1 2s it was prolly a merv

What is a merv? 

EDIT: Oh I guess the mini 1/16 is called the merv? I dont think it is though cause the ad says 1/10. Also the ESC is a 120a. Isnt the merv smaller than that?

Is there a way to tell a difference between the two based on pictures? If it was a smaller one thatd be ****ty.

well yea you can tell the difference if the shells are off. If not they look pretty much identical, and with some creative photography you almost can't tell. I saw a pic of a merv that I mistook as the full sized revo due to the angle it was taken a while back

and yea 120A esc is the revo

but still $250 is almost too cheap for one that is RTR

Thanks. So after hearing the input from yall I bought it. I'm glad you mentioned the merv cause I made sure to check the internals and compare to see what's going on. From the outside they look identical. I thought I might  have been getting scammed. But it wasn't a scam. I think what happened was a lot of people inquired about it and he started to lose patience with people cause it was set at a good price. This type of situation is rare but I do a LOT of business and transactions on CL and it looks like it was a scenario where the guy just wanted it gone. Want it gone fast, no hassle, done deal at the price he asked which was more than fair. This in turn, brings out of the woodworks a lot more flakers and lowballers than if you would put the price higher than average. It's funny how that works. If you want to sell it fast and value something lower than average, people assume its tainted or you don't care and come hard with lowballs and I think that's what did it. Understandable cause I've been at the seller's end with low ballers and lollygaggers before. 
Sometimes when someone prices something too good to be true, it's either broken or a scam, or someone who needs or wants it gone without problems. It's a rare find but when it comes around, gotta pounce! 
I wish I knew about rc cars a bit more, it would've made the decision a lot easier. 
Anyway thanks to all the forum members, I got a car to start off on. Came with a bunch of extra parts. I dont know enough to know if something is bad or damaged from full inspection and things are good, suspensions are good, demo was good. Only need to get the batteries and charger now.

I have an Imax b6 charger on the way i bought from someone online. 

Can yall help me pick out batteries that won't burn my esc or motor to the ground? Running almost 100% on grass. The motor is a 1900kv brushless and ESC is hobbyking 120A. There's a video of someone running the hobbyking 120A with 6s with good success on his Turnigy Trailblazer 1/5 (same as redcat shredder) and he says it's doing very good. I dont know about my motor though and gearing and things so any help appreciated. There are two battery slots/compartments but only 1 connector from the ESC which is weird. Do I need to get a splitter or something? 

Looking to maybe get 2S 5000 mah at 20C which is the cheapest but if the small $ increase in price for a 3s 5000mah at higher Cs will be better, I'll get those. Hobbyking has good prices on batteries and a 2s and 3s difference for the same MAH and C are only a few dollars. 

BTW, this e-revo is BIG as hell. WOW. Is this all 1/10 rc cars? Isn't the slash a 1/10? Seriously it's as big as my 21" monitor. I thought it would be the size of a large shoe box or something. It's what I thought a 1/5 redcat would look like.

Is this the ESC you have?

http://www.hobbyking.com/hobbyking/store/__17235__Hobby_King_120A_Sensored_Sensorless_Car_ESC_1_8_1_5_.html

It says in the specs it can only be run on 4S.

You will need to wire your ESC in a series or get a series connector to run 4S. What kind of connectors do you have?

Yep I believe that's the one. So technically only 2 X 2S running in series to get 4s for the ESC right? I know people run 6s I just dont know if I should do it. I'm sure it can handle it and I read somewhere that it's a remake of another brand that has 6s in the specs but I dont know much about gearing at all. Especially running heavy in grass. 

I have deans connectors coming out the ESC but only 1 of them.

the shredder is cheaper right now cause they are liquidating them....and selling them WITHOUT the lipos that the 8E's come with.
On the backdraft....thats a fun buggy. It handles much better than the earthquake and due to the smaller tires (mostly smaller width, not that much shorter) it tends to break less. Smaller tires and shorter arms put less stress on parts.
The backdraft is easier to control in the air. The earthquakes tires make it better in snow/sand and such, but you can do some pretty good offroading with the backdraft.
depending on what price you found the backdraft for, id say go with that.
I just bought a RTR earthquake for $110 off a RCU member. Got lucky with that one.
But the backdraft I owned last year I snagged for $175 RTR with lipos off ebay.

Heres How Id rate durablility on these models, 1 being best and so on
1, backdraft
2, aftershock
3, earthqake
4, and of the shredders

You may also want to consider the XTE models. They are based off redcat's professional 1/8 nitro line. They have simillar electronic setup as the 8E's, but they have a more common 1/8 scale chassis layout.

You made a very good choice with the e-revo over a redcat, Ive been in the hobby for about 4 years and have had 7 different rc's and the revo if my favorite so far, i loved it and i hope to get another one before long.

I think what happened was a lot of people inquired about it and he started to lose patience with people cause it was set at a good price. This type of situation is rare but I do a LOT of business and transactions on CL and it looks like it was a scenario where the guy just wanted it gone. Want it gone fast, no hassle, done deal at the price he asked which was more than fair. This in turn, brings out of the woodworks a lot more flakers and lowballers than if you would put the price higher than average. It's funny how that works. If you want to sell it fast and value something lower than average, people assume its tainted or you don't care and come hard with lowballs and I think that's what did it. Understandable cause I've been at the seller's end with low ballers and lollygaggers before. 
Sometimes when someone prices something too good to be true, it's either broken or a scam, or someone who needs or wants it gone without problems. It's a rare find but when it comes around, gotta pounce! 
I wish I knew about rc cars a bit more, it would've made the decision a lot easier. 
Anyway thanks to all the forum members, I got a car to start off on. Came with a bunch of extra parts. I dont know enough to know if something is bad or damaged from full inspection and things are good, suspensions are good, demo was good. Only need to get the batteries and charger now.

I have an Imax b6 charger on the way i bought from someone online. 

Can yall help me pick out batteries that won't burn my esc or motor to the ground? Running almost 100% on grass. The motor is a 1900kv brushless and ESC is hobbyking 120A. There's a video of someone running the hobbyking 120A with 6s with good success on his Turnigy Trailblazer 1/5 (same as redcat shredder) and he says it's doing very good. I dont know about my motor though and gearing and things so any help appreciated. There are two battery slots/compartments but only 1 connector from the ESC which is weird. Do I need to get a splitter or something? 

Looking to maybe get 2S 5000 mah at 20C which is the cheapest but if the small $ increase in price for a 3s 5000mah at higher Cs will be better, I'll get those. Hobbyking has good prices on batteries and a 2s and 3s difference for the same MAH and C are only a few dollars. 

BTW, this e-revo is BIG as hell. WOW. Is this all 1/10 rc cars? Isn't the slash a 1/10? Seriously it's as big as my 21'' monitor. I thought it would be the size of a large shoe box or something. It's what I thought a 1/5 redcat would look like.

traxxas has no idea what scales are
as for batteries you will want 30C minimum for the ESC at around 5000mah
I know a few good batteries that are pretty cheap, but don't know the dimensions of the tray

Thanks! So you wouldn't try to go for 3s instead of the 2s with the esc/motor that's on the car right now?

personally no I wouldn't recommend it either as you haven't even driven it yet
if you find it too slow on 4S you can bump it up to 6S. But just remember 6S pushes most RC's the the breaking point, and they WILL break and fail often

ah youre right that is true. don tneed things to break and need to learn to drive. but lipos so expensive.. 

would it make a difference if i went up to 40c or higher or is there a reason why you chose 30c? what about 20c?

20C's won't cut it there's math to do but in general they will swell up, and if you try and charge a swollen battery there is an extremely high chance they will ignite and pretty much can burn a house to the ground.

As for why I posted that one well I use 2 of them on a 150A system, and had no issues yet, and think my batteries are nearing 2 years

Generally here is how you figure out what the battery can take
(mah rating X the C-rating)/1000 = constant current it can output
example the 5200mah 30c batteries I linked can put out a tad over 150amps constant.

so basically you can't have too high of a C-rating but can have too low of one.

I will say only issue with the batteries I linked are the wires on them ae a royal PITA to solder a connector on due to how thick the wires are. But then again you will need to learn somehow

ive been using the sky lipo brand packs off hobbypartz for awhile now. both the hard and soft case packs.
Ive had 2 fail...but only after a year of use. A few others have lasted a few years now.
And since the sky lipo 2s 5000mah 30c/60c pack is only $25...a pair of them is only a tad over $50 shipped. And thats cheap. You can spend almost as much for a nimh pack!

Thanks. So I might jsut stick with the 30C then. I wish the battery tray would fit a 4s in there cause then I could just wire up a 5000mah 4s battery and charge once instead of rotating and charging 2 different batteries. Or 4 if I get 2 pairs. Maybe there's a battery compartment mod I can do.. 
 
Damn I need to learn how to solder. I bought a solder kit to try and repair my earphones and it was an utter fail. Why are deans plugs the standard and if so, why do these batteries come with banana plugs??
 
So two of those batteries either Skylipo or turnigy and I would need a splitter cable right? My ESC only has 1 cable for a battery. I would need a serial splitter? Here's the esc i have. http://www.hobbyking.com/hobbyking/store/__17235__Hobby_King_120A_Sensored_Sensorless_Car_ESC_1_8_1_5_.html I dont know what the 3 cables do. 

also, there are like 3 or 4 of the same Sky Lipo batteries listed on this page. Turnigy also has very similar or same spec batteries on their page. Why is this? Is there a difference I am missing? http://www.hobbypartz.com/skylipo2s30c.html

Something like this? http://www.maxamps.com/Deans-Series-Adapter-12.htm

SPC have a 2S 5000mAh 30C pack for $28 and you can choose either Traxxas or Deans connectors.

http://spcracing.com/index.php?productID=125

Here's a Deans series connector, although wiring your ESC in a series would be the best option.
