Novak HV Maxx or Neo sphere
 

I have know nothing about brushless, and i never even thought about it till yestorday, so i have alot of questions. I have a rustler, but its all disasambled, and misssing parts, so i was going to pick one up cheap on ebay. I want to run it in the sand, but want it to have good torque, and speed. I eaither wan toget the Novak HV Maxx, or a LRP sphere neo stage 2. They are both around the same price to. The only reasion i would get the HV maxx is so i could run 14 cells. I also have a Tamiya horet, but i think a brushless motor would ruin all the gears. Will the Sphere neo have close to the proformanace as the HV Maxx? What speeds could expect from both? Which would have best torque? I just want a simple system, thats not to expencive, and goes fast.

Also what are the lipo batterys? Are the better than the common mah(not sure about name)?

Stick with the sphere the hornet will handle that. as for the speed it will be a handful. Lipos are a different makeup than nimh, it uses lithium instead of nickel.
I don't yet know as much about either as some others here so i'll let them elaborate.

Welcome to the forums and keep reading, every page will teach you something

The hv maxx is made for a monster truck. It has gobs of torque. 14 cells is a lot of weight to run as well. I am not sure what your goals are. Some of the guys like the novak systems as well. Welcom to the forum to. The lipo is a lighter built battery pack. It retains it voltage bettery than the older nimh and nicads. It does have a few down falls. They are little more sensitve to what you do to them.

Ive been reading alot of threads here, and people either hate the Novak HV Maxx, or love it. 95% hate it and about 5% of the threads i read. it might be just bacause the weight of the e-maxx. How fast will a rustler go with a neo stage 2, with 7 high quality cells? Could i safly run 8 cells in the neo? Safly meaning like without risking blowing it up?

chances are 8 is a big no-no. im not sure about how fast it would be but the gtb 4.5 is another option if your looking for speed.

I saw this video of a sand dragster, and it was a rustler, with a hacker system i think, and 12 cells. Heres the link http://www.rcrockgear.com/rbgerrish...rich320x240.wmv

If the link doesnt work try this http://www.rccrawler.com/forum/showt...t=30603&page=2

Its post #49

I think i might just go with a sensoreless motor. Is this the esc that you can program for Acceleration, or top end or something like that. will i need anything else? And can i use the plane 4s lipos from towerhobbies.com? Are they really crapy because there cheap.

This is what i might get

I would not even think about using an L sized motor in your car, the S is more than enough.

For a speedcontroller, and the fact that you want to use Lipo, i would personally take the MGM controller, it is meant for car use. I ordered an MGM too, they seem to be as smooth as possible. plus they have the ability to be programmed to do a shut off when the lipo's voltage drops underneath the 3 volts per cell.

Your question about the Lipo-cells from towers.. what lipo's? got a link? The 8S can take quite some current from your lipo's. so you need a few good ones.

If you go for an 8S 4S lipo is just too much. 3S is insane on the 8S.

Depends on how big of tire you got or going to run. alot of the guys like the 380 can size better than the 540 can size. I don't know cause I am newb at running the smaller stuff. You could go with a 12s with 4s lipo.

Here is a link http://www2.towerhobbies.com/cgi-bin...po&FVPROFIL=++

Are liPo batterys more powerfull than the standard c size battery's or just alot lighter than c size so it makes them faster. There ment for planes right?

I read a post about the MGM not haveing good costmer service, and it gets fried alot.

I am curious, where you find that thread, because here at rc-monster i haven't read anything negative about their products. It are the schulzes that are a concern in both meltdowns and customer service.

No, you can't say lipo's are more powerfull than standard C-size cells. It depends. They both come in all sorts and flavours.

With brushless you need the most powerfull batteries you can find. Lipo's are not meant for planes, they are meant for delivering much energy at a low weight.

With a lipo, you need to worry about the 3V cuttoff, otherwise the cell might be damaged.

When you want to use lipo for your truck, you need about 15-20C discharge rate and a capacity of about 3-4000 mAh

Here is the post from the thread. I've used a Mtroniks Genesis Truck and a MGM Compro 12012.

Mtroniks - very smooth, WATERPROOF, great customer service (2 weeks total from California to England, no money paid except for shipping there). Reliability isn't bad, had only one go up in smoke. This controller doesn't seem to like external BECs, my XUS Hobby UBEC causes terribly stuttering/glitching on my Truck with the red wire removed from the receiver connector, but is perfectly fine using the built-in BEC.

MGM - very smooth, brakes that do weird (bad) things for racing/track running, not so good customer service. Sent in my damaged (I think from water) 12012, and repair took 6 months, during which time none of my 10+ emails were responded to (from multiple email addresses, including from Mike). So far on my replacement the BEC has blown out on 4s Lipo (it's visible on the shrink wrap), whereas my Mtroniks Truck is perfectly fine (so far) using the built-in BEC on 4s Lipo.

I guess now im definatly going brushless now, because i also have a duratrax delphi indi car, and the stock tires have no grip to i put some hornet tires on it, and it griped relly nice, i put the GPS on it today, and it went 35.2, on a wet rode. I put a $20 13t motor in it. I was going for a nother pass, and i was 1/2 down the rode, and it just costed to a stop. I figured i was done anyway so looked at the GPS, and saw the speed, then whent to unplug the battery, and it nearly burnt my finger off. Then i covered my hands fith me swet shirt, and i pulled preety hard, and it wouldnt come apart. I walked home, and sniped the batters wires with plyers, and the last esc i have is trash, but what about my battery? Its a really good 6 cell battery that i only charged 4-5 times, so i better not be fried. Im 13 so i cant get a job till im 14, so its hard to make money, but if i sell my rc boat, and gravedigger tuber, i can get $580. I dont know what i should do. I really want to start saving up for a real car when i get my driving license (70 Nova), but im going to have to get a brushless sooner or later, so i might just order it today. I have $400 that i wanted to save. I was going to ask for the brushless for my birthday (May 28), i might ask for a aluminum pede chassis. But where can i get a crapy used rustler with no electronics, for around $50?

If you had a tamiya connector on it. The connector may have failed. It not connection the esc can't work.

you have many options, but know this although cost effective (novak) you will quickly out grow the system, it is very limited and as far as batteries my 2 cents lipo's are the way to go 2s 3s on an mgm controller and lehner 5300 i run 50 plus mph all day long in a fortified rusty

Will the feagio 8s (sp) go as fast as the lehnar (sp) 5300?

I have heard people running like 9cells on a 8s. I seen a video of it and it looked pretty quick.

Whats the limit on that it? I thought you could run it on 12 cells.

I am not sure about 12 cells but have seen 9. 12 would be pushing the motor some.

Will the MGM 80 handle the 8L? on 10 cells?

The 8l would be putting the mgm thru is paces. I think to be safe the 12012 mgm would be better.

How about the castle creations 120

How fast will a rustler go with a 8s on 8 cells? I cant afford the lipo.

How does all this stuff sound?

- castle creations 80 = $170 (Only want it because it waterproof)
- 8s = $65
- Triton charger = $120
- GP3700 battery 8 cells = $65
- New Rustler = $120 (used $90)
TOTAL = $540

Can i find a charger for cheaper? Like $60-$80?

There are cheaper battery chargers that will work. That accually sounds like a nice setup for a rusty. The guy on the other forum camel rc is a member here. He has ran the 8s feigao on 9 cells in a hpi mt2. He had a video around here of it. You could find it and check it out. I think you like what you see.

im pretty sure the esc your talking about is for planes and will not work for rc car use.

Ok after all the sugestions, and comments, i think ive made up my mind. Im going for the 12 cell limit, so i can always upgrade. Since im short on cash right know, im going to get this.

- Rustler
- MGM 120
- 8L motor (which shaft size should i get)
I plan to run this set up on 6 cells till i get the money for 10 or 12 cells. If i run two 6 cells i wont need a new charger, because my charger only charges 6 cells at a time. What charger would i need for 4 cell lipo? I added everything up is i went with the 12 cells it would total at $500 if i go 8s MGM 80 its $570. Will the 8L and MGM 120 run good with only 6 cells? Will it get to hot with 12? I should be finished with this truck my late May or early June.

a ice would be a good choice. the 8L, like previously stated, is to much for a rusty.

Go to post #49. Theres a video of an associated stadium truck, and its run on 12 cells.

Im only going to run this on sand with paddle tires, wont the bumpy sand make it slow down

its not that it would be to many cells...the 8L is litteraly to much for it. its to big, to heavy, to powerful, to long, ect. the S is the right size, ect.

If you get a 12s you can run 12 cells on it. It won't have the same power as a 8L will. I think you may be underestimating the power of a brushless motor. My brother ran a 8L in a emaxx which is like twice the weight or more of a rusty. It was breaking up stuff in the emaxx.

What motor do i need to get this truck to run like the one i the video? I might go with te RC10T4. Does anyone know if this is a strong truck? I think the tranny is better that a pede. I wan to be able to go around 35-40 in sand.

I was looking at his in the video. It looks as if he has a s can or 380 on his.I could not tell. It looked more like a 380c. If that is the case the 12s is probably what he had. That is just a guess though. Search thru and find the one of camels mt 2. On 9cells it was kicking like the buggy.

I found rc camel's thread, but the video wouldnt work. Can a 12s go that fast, and proform that well? I made a list of posibilities (sp) I think for know ill go with The last one then eventually ill get the Lehner 3100. If i can talk my parents into geting me the $200 truck that would help alot, so then i would go with the Lehner 3100 first. i read that the Feigao's have bad bearings, and sand can get insdie the motor and ruin it. The Team associated RC10T4 Factory truck has a aluminum motor plate, so that would help cool the motor right? Will the 3100 Lehner last long running on 12 cells?

i've got a ft t4 and its an awesome racer. the only things i've broken are 3 fr arms, 1 rr arm, and i rr body/wing mount. this truck has been in some nasty crashes and seems to be ok. as far as bashing it, i've heard they aren't real tough. also, the tranny is pretty strong, but the diff requires work to hold up to brushless power. i would replace all the steel diff balls with some good ceramic diff balls. they'll last a whole lot longer. hope this helps!

p.s.- i run a gtb 5.5 in mine, pretty fast, likes wearing flat spots on my diff balls.

For those of you that watched that video, I made it. I was the one with the t-maxx, and the electric was a friends T2. It runs a hacker C-40 with a Quark 80B controller.

I'm not sure what he was geared that day, -but I can find out. Yes, it is fast.

I'm running my T4 with a Lehner XL-4200 and a 3S pack, and I can almost keep up with him, -but not quite.

That's a pretty hot setup he's got, -but it's heavy with 12 cells onboard.

Hopefully you guys like the video. It takes roughly 1 hour per minute of video, -a lot more than people think!

that was a cool little vid man is that t-maxx running an rb323? it seems like it's got some kick...and James running 12 cells you have ot also account for the sus. it'll be a little softer with the extra weight...if you save up and get 3s lipo pack it should give you around the same performance as 12 cells with less weight...though i am not 100% sure cause i am new to the lipo and bl scene

OH BTW i have a reedy neo 9turn with sphere combo in my rusty on stock gearing and it's pretty darn fast...waiting for a rebuild cause i broke the front sus. and stripped a spur..so now it's getting a full alu make over.......this motor is pretty fast with only 6 matched 3700's i can't imagine what it'd be like with li-po's and better gearing...it's pretty fast now but i gets too hot...so i need to re gear...and luckily i haven't chewed up my idler gear cause it's not even aluminum.......rusty is a great truck for this type of thing imo...y buy another car when you can get a rusty off ebay for cheap...I see them go for like $70 and lower all the time as roller

It's the Sirio .23, -which is basically the same engine. It has an RB 086 pipe and is geared 20/72. Yeah, it does have some serious power. I finally got the drivetrain to the point where I can go and run several tanks of fuel before I grenade something. Thanks for the compliments on the video, -I never would have imagined that anyone from this forum would have found it, but the internet makes it a much smaller world.

Yeah, my 3S gives his 12 cell rig a good run for his money, but it falls just a little bit short. Some more gear, and I could easily pull him with my 9920 controller, -but it would get hot. Geared the way it is right now (20/87), the power meter shows max current at around 90 amps, -so I'm already knockin' on the door of being "done", -at least with a 3S. I have the advantage on overall weight, -his rig is heavy, -which does make it more stable at the higher speeds.

this is true......i wonder if you bumped up to 4s and ran a fan on everything would you smoke him? I just bought two 8000 mah 2's and 1 3s and a hyperion charger....for my bl project...it should prove to be pretty darn fast

Oh yeah, I could spank him easily with a 4S, -and it probably wouldn't overheat if I geared down (which I would need to do anyway). I know that my 7020 can tolerate short 90 amp bursts without going thermal, -so I would like to think that the 9920 would be good for a short run at 120-130 without shutting down.

So, how are you going to arrange your (2) 2S (1) 3S setup? -Or did you plan on even doing that?

I'm always curious about people's success/failure stories about mixing and matching lipoly packs in series and parallel setups.

Regardless, your setup will be plenty fast.

BL RULES!!
