e-maxx brushless recommendations

[suvowner]

I am a new e-maxx owner of about 2 weeks and can't quit upgrading............so obviously brushless is the next logical step............i have some nice 14 cell 4300miah packs that are great, just this upgrade has broken both rear cvd, center cvd and rear diff spider gears.............those are now all upgraded to steel and a spool in the rear diff............now my dillema is which brushless system to go with...............I am not a skilled installer or solderer...........i mainly plan to bash so longer run time is an absolute requirement over stock..........but if i wanted to try and do a race just for fun i don't want to get blown away by nitro monster trucks, since in my area there are never enough electrics to have a monster electric class, I would have to just run with the nitro's..........i will say the speed even for the stock motors on good 14 cells is hard for me to control

hv-maxx -
pros - easy installation, sensored which will be smooth power when rock crawling type stuff, works well with existing 14 cell packs, pre-wired to the esc
cons - not as powerful as some of the sensorless systems, lacks low battery voltage cut-off if i run lipos in the future

castle creations momster mamba max - proposed 2000 watts might be too much for me, and seems to have endless launch delays

quark, plattenburg, lehner, fiago - i just don't have any idea what would be better and what about each is worth the money........the multiple combinations of speed control and motor is very confusing.....I don't want massive power if my run time is only 10 minutes..........any low speed cogging would just drive me crazy.........any thoughts or recommendations would be appreciated.............

Well first off, welcome to the forums! I think what you would like would be something like a Feigao/Wanderer 10XL and Warrior 9920 or maybe a Quark 125. The Quark is the best of the 2 but obviously more expensive.

[suvowner]

thanks for the welcome........well ok, can you elaborate as to why you think that is a good combo.........if money was no object what would be the best baterry/esc/motor combo available, and why??

I get the sense quark is prob the best esc.........maybe lehneror plattenburg is the best motor ??

would any of these systesm absolutely be as smmoth as the hv-maxx at very low speed ??

[squeeforever]

The Quark is a VERY smooth esc and with an XL motor there would be almost no cogging. However, if money were no object, the 1950/8 on 5 or 6S lipo with a Quark 125 would absolutely be the best.

[tallyram]

i can testify to the 1950/8 on 6s lipo. it is very powerful, but i wish i would have known about the quark first. my bk 12020 does ok, but it seems like most of the power is on tap after 3/4 throttle. that makes it hard to control on the track. you can't go wrong with what squee suggested!

[suvowner]

ok you got me thinking...........what is actually better between the 1950 and the xl..........also what would this do to my run times ?? I was thinking maybe the 8000 miah 3s lipo from maxamps would be the ideal battery !!

i don't want to knock the xl motors, but i think everyone will agree that the lehner 19 series are superior in every aspect except price. the xl motors are awesome motors for the money. i'm sure either way you won't be disappointed.

should i go with the ease of hv maxx?
or the speed or another setup such as...Feigao 540c 9XL motor+Warrior 9920 Car Controller...
would this be faster than the HVmaxx?

[squeeforever]

It would be WAY faster than the HV. The Feiga/Warrior setup is much better.

[suvowner]

I appreciate your input but way faster and much better sound inticing, but it is hard to get a sense of how significant the difference realy is ?? Could you by chance offer some real world numbers such as actual top speed difference and actual run time difference ???

[squeeforever]

I would estamate around 40 mph +/- and about 20 minutes runtime. Both better than the HV.

9,8,7 XL whats the difference between the 3?

9920warrior & 12020 Warrior whats the difference

[squeeforever]

What difference are you referring to? Speed? Runtime? Overall? The main difference is how many winds it is. 9XL= 9 winds.

So 7xL is faster than 9xL?

When selecting a motor you need to consider more than just the winds. A system like this needs to be panned out before you start buying. (trust me I learned this the hard/expensive way) Plan out what batteries you will be using. Look at the KV rating for the motor. You should shoot for a motor where the rpm on the batteries you are planning to run is round 75% of the max rpm limit of the motor. Much more than this can cause heat issues in the motor, less and you are not getting all of the potential out of the motor. Now you need to decide what is more important to you, Speed or run time. If you want speed you should select a lower wind motor that will rev a little higher. If you want run time, select a motor with a couple more winds resulting in slightly less speed, but more power and run time.

As for the esc... Don't skimp or you will just wind up buying another one later. If the power rating on the esc is close, my recomendation is to go with the next higher power handleing model. In my opinion this is the bigest mistake that most fist time buyer make. (Myself included) Thinking that they can ''get away with it'' and save a few dollars. Lets face it, its a big investment either way. You might as well do it right the first time and in the long run you will save money.

These brushless systems are fantastic if set up well and frustrating if they are not. It is a critiacle balance between, motor kv rating, motor size, esc Amp rating and the voltage you plan on running, and tie all of this together with the budget you have.

Summary / My recomendation. It sounds like you are planning on running 14cell NiMH, so pick a motor that is on the conservative side of 75% the motors max rpm. You can always add an extra cell or 2 to the system later if you want to pop the speed up. Then get the best/highest amp rating esc that you budget can handle.

These are rules of thumb that I have been learing over the last year or two. Nothing written in stone and there are way more experienced peole on this board than me, but this is my $0.02.

If you don't want the fun/challenge of figureing all of this out and understanding it all, then get the HV. All of the thinking is done for you, its a simple out of the box solution that will bump you up from stock. You woun't be slapping the nitros around with the HV, but it will be a ton of fun.

I know, long winded.... I have that habbit. Sorry.

BTW... I agree with everyone else that has answered this. I love the Quark. Gets my recomendation.
