j.m.

there is no other way to do it. You HAVE you use a 5mm bore pinion. Also, why would you not want to use lipo's? (unless you already have the other batt's) You could use a 5s or 6s pack that will have almost 1.75 times the voltage, and also have half the weight!
But if you insist...

You will see a little more power with your two nihm packs unless you choose to use 5s or 6s lipo's. The MMM will absolutely LOVE these, and you will definitely be doing wheelies all the way down the street.

well im not looking into spending that much on batteries just yet, i wanna try the MMM on 14 cells first then ill decide, and as for the 5mm bore pinion, i want stock emaxx pinion teeth which is i think 18? so can i get a 5mm bore pinion with 18 teeth? and if it is yes can i have a link?

SavageX78

Actually the new emaxx comes with 19t pinions but the biggest 5mm i found was 16t http://www3.towerhobbies.com/cgi-bin...?&I=LXUAY7&P=7

j.m.

that neu motor will most likely put out more torque than both brushed motors combined, so i would say you want about a 20-22 tooth.

MaxxOrange

im not getting a neu motor, im getting the MMM combo, also how many teeth is that big bore pinion j.m.? is it stock new emaxx gearing?

j.m.

you'll also want one of these:

j.m.

WWWWWWWWWWWWWOOOOOOOOOOOOOOWWWWWWWWWWW!!!!!!!

The MMM combo HAS a Neu motor in it!!!!!!! That's the only reason why it's worth the $300 price tag!!!!

And you choose the size you want in the drop down menu.

MaxxOrange

oh im sorry i didnt know there was a neu motor in it..well thats really good anyways, and 300 bucks isnt bad for the combo IMO, and i thought the new emaxx comes with the steel idler gear, and what do you mean by "choose what you want in the drop down menu" will there be different versions of the MMM? like not all of them will be 300 bucks?

j.m.

i wouldn't start to price the MMM until it comes out, what i was saying is to choose the pinion size in the drop down menu on rc monster.

i think you should read this post on rc-monster.com by a design specialist Joe Ford who works for castle creations

yeah i know the date is off but the president of CC patrick announced it will hit shelves april 21st, i posted a link in one of my previous posts
but here it is anyway http://www.rc-monster.com/forum/show...&postcount=484

miniguy

have you looked at the hv maxx series?

and the velinon motor has quit a bit of power to push the e-maxx even with a single, type it in on you tube

MaxxOrange

yeah i have seen the single vxl emaxx on youtube its pretty darn fast, and no i dont want the novak because its sensored and i hate novak. i am still thinking about the single vxl but i heard its not for long term use, maybe it is im just now hearing from the right people, i wanna hear about the single vxl emaxx that have a single vxl emaxx, not peoples opinions, but it depends because im still looking at the MMM. but thanks anyway for telling me

j.m.

using a single vxl motor would work, but lipo's and lighter weight wheels and tires would be almost necessary to decrease the weight. What would be nice is two vxl systems running on two 3s packs in parallel for HUGE run times. (and alot of power.)

The prolem with the novak systems is i don't think they really like lipos. Sensored isn't bad, i actually prefer it because it's alot smoother. The main problem with the large novak motors is that they have 1/8" shafts. Most people will easily be able to snap them on an emaxx. They do sell a 5mm upgrade kit, but that just adds to the cost, and pretty soon your spending more than you would for an extremely nice Neu motor, and a mamba esc.b

MaxxOrange

lol you mean like the MMM? so if i bought 2 vxl systems at my lhs and didnt buy a single motor plate, how would i synchronize the escs? is that extremely hard to do? because if this MMM thing doesnt work out, then i will go for the dual vxls

SavageX78

I dont know how to sync them but I do know its not hard. In this thread http://monster.traxxas.com/showthread.php?t=402486 he says he useing a Y-harness Between the escs to sync them. Seems pretty easy.

j.m.

You don't have to "sync" anything. If they are the same thing, then hopefully Traxxas's tolerances are small enough that the motors will perform in a similar fashion. You don't even have to use a y-harness. Those are mostly for airplane aileron servo's, and just add to the length of the wires. You can clip the lead off of one esc, and then splice the the wires of the other one into it. If you don't forget to put the shrink wrap on the wires (near the plug end) before you solder, it will be a very clean setup.

MaxxOrange

lol i could either do this buy buying 2 16o dollar vxl systems which is 320 bucks, or i could buy the MMM system which has a neu motor thats more powerful than 4 vxls combined which is a better system for emaxx and is also 300 bucks. what do you guys suggest
after all the MMM comes out 2 months before i get the new emaxx

j.m.

Over all others, i would suggest the MMM on 6s, 7s, or maybe even 8s.

(if you can handle it.)


(and the ca you use to glue the tires on the wheels)

MaxxOrange

what do you mean CA glue, i know what it is but why u say it? and yeah i can handle the MMM on lipo.

j.m.

What i'm saying is, a neu motor on 8s lipo (30 volts) Will produce about 4.5 hp and will litterally balloon the tires so much that they will rip right off the rims. (the CA(super glue) won't be able to hold them on). I doubt anybody could handle that much power unless it was on a large boat.

SavageX78

Ya thats insane 30v!! I know for sure i couldnt handle it. But id give it a good try.

rhylsadar

hi

wow there is much confusing information in this thread. just a few comments.
the turnigy esc that was suggested above will not have reverse. its practially a airplane esc. as for the turnigy motors that were suggested you would want one with that is labeled with B36 and 56 not 50 like the one suggested above. i have some of those motors here and its clear: you get what you pay for. they are super cheap. quality does not look very good. performancewise i will see how they compare to other 'cheap' motors.

then also with those 5s and 6s lipos that are constantly recommended here i would be very cautious. first you have to check carefully the dimensions that they even fit in the maxx. second mounting a huge 6s lipo that weights 700g on one side will make it quite cumbersome to get a well balanced setup. i would rather look into two 3s batteries and then wire them up in series.

i don't know how j.m. can suggest this steel idler gear as it is made for the OLD e maxx tranny and will not fit into the new one. you seem to suggest many wild things j.m. it doesn't make the impression you really know much about many things you 'suggest'. please do not take this as an offence but may be you should be a bit more reluctant with your statements.

chosing the right components for a brushless monster truck is not an easy task. for instance if you will buy a MMM with a motor that is licensed through NEU (but is NOT a neu motor) you will most probably fry your cheap venom packs you already have. also this set will draw many amps and so it is important that the lipos can deliver high current amps. so cheap lipos will not really be the way to go here. the new MMM is rated at 6s. if it will be able to handle 'easily' 8s etc is pure speculation. we will see how those things hold up. furthermore 8s on a e maxx is an absolute crazy power setup.- from what i read of the thread starter that is absolutly not what he is looking for.

the single vxl setups with 3s work ok for some people with lightweight setups if you gear significantly down. if those setups will still work in the heat of the coming summer remains to be an open question.

the HV maxx with the new 5mm shafts is also a nice drop in option so far. on 4s it will sure be nice on a track. sure not as powerful as a MMM or other high quality setups.

if you want ot use a MM with a XL feigao motor or something you need a external BEC that i would use even with 12 cells. that takes a lot stress from the esc.

the quark monster pro and a NEU will be a high level setup. it has its price though.

if the MMM esc is coming out soon there is a high probability that it will be one of the nicest esc for the price.

Nice bit of clearing up the Rhylsadar. Maybe a bit harsh on J.M. there as he may not have realised a new E-maxx was being talked about, rather than an old one. However he should be a bit more careful with statements like 'it HAS a Neu motor in it!!! That's why it's worth $300!!!' etc. As Rhylsadar pointed out, it is a motor BASED on Neu architecture, not a Neu motor. The pricing for an MMM is going to be 1/3rd motor and 2/3rd ESC, not the other way around. The neu you are talking about $225-$250 JUST for the motor, and as such the MMM motors are likely to be lower quality and built from lesser materials. That is not to say they won't be tremendously powerful, however I would hold off on saying they will be the be all and end all of high end Brushless systems, we will wait and see how the motors handle high voltage and RPM under big strain in a monster truck over extended periods of time. They may fail more frequently, or have build issues, or be less efficient, or they may be fine, we will simply have to wait and see.

I have no doubt that the system will be the best system available for the money. That is a given. But whether that is because of the ESC alone or ESC and motor remains to be seen. Particularly as the system has been in developement for an awfully long time and we are still getting an initial release without the motor to partner the esc, which may suggest they are having problems.

i have had two of the hvmaxx 4.5s dont get one they burn up too easy, i ran mine under the specs (14cells) and they both still burnt up for no reason, one cracked a voltage regulator and the other smoked an internal capasitor.
a single vxl can work it just needs to be geared down from the stock gears, as long as the temps stay good and the motor has a low enough gear ratio to not bind then it should work fine, personally i would put two vxl's in it
