Brushless for E-Maxx

[Dan-o]

I may be picking up an E-Maxx very soon, any suggestions on a Brushless system?

[cart213]

How much do you want to spend?

[Dan-o]

$200-$250 max. I have a while to save, so suggestions beyond that range are cool as well.

[glassdoctor]

A Feigao 540C 9L and Mtroniks Truck would be in that price range. Can't think of a better choice for less.

I will be testing that very setup pretty soon in my old emaxx.

There is also the Novak HV too...

[Rtsbasic]

The search function is a wonderful thing.

But, I would recommend the same as glassdoctor. I previously ran a Mtroniks Truck ESC/ Feigao 8L combo and it was impressively powerful. Did run quite warm but with the 9L it should be fine.

Email Jamie at www.starluckrc.com, you never know he might be able to do you a combo deal or something.

if you want darn fast support and advice go with the novak hv-maxx. its not a bad system for around $300 clams. i have a hv in my all alum. e and i have never failed to run with the bigger mills.

[Rtsbasic]

The Mtroniks Truck/8L combo is faster than the Hv-Maxx. Mtroniks also have better tech support, and its valid for significantly longer than Novaks. Not to mention its a lot cheaper. I can't honestly think of any good reason to recommend a Novak HV system these days.

[hivemind]

well rts i can't really disagree with you on the faster part but as i said setup is everything. my hv has never let me down nor any of my novak stuff of which i have been using for more than a decade, running them in my rides whenever i get the chance. on the support issue i would have to very much disagree which is not to say Mtroniks is not a great company but its been my experience that novak is faster in response time. i live in michigan, usa, so the guys in my area with the european systems have some issues with support. with that being said dan-o there are a lot of them out there and depending on location i look for a reliable, low cogging mill i can get fast support for. both the novak and mtroniks stuff is good, but with all due repect to rts, i choose novak.

[Dan-o]

will the 4.5 HV motor run with a differant speedo?

[glassdoctor]

Technically yes, it can run with sensorless controllers.... you just don't use the sensor wires.

But some have reported that the sensored motors don't run very good on their sensorless controllers. Some say it works fine for them.

But I wouldn't bother with the HV motor if you run a different controller... it's really too high-rpm imo anyway for a monster truck.

[Rtsbasic]

Sensorless controllers won't drive Novak motors smoothly, not due to the fact their sensored, but because the way they are constructed. Apparently the U-Force can drive a Novak smoothly, but it wouldn't work with the HV as its not rated for enough current.

hivemind, thats great your happy with Novak. No doubt they're a good company, but I respectfully disagree their support is faster. Novak will be faster in the US because it doesn't take as long to ship equipment to/from them. If I phone Mtroniks up then send a faulty ESC in sameday, I normally have the replacement in my hands within 72hrs. I believe Tcolesen on these boards sent one in from the US and the total turnaround was approx 10 days? And if you ask them, they'll provide a full explaination as to what went and if it was due to bad design, user error, etc. One time they even customized the design of a Mtroniks Truck ESC slightly due to the way I damaged the previous one (partial user error). Will Novak offer you this level of support, and are they this quick in general? I don't know, their UK distributor isn't that good to deal with and Novak won't deal with direct customer complaints from the UK as far as I know. Mtroniks cover the costs of return shipping as well, even if you only send the ESC in for a software update. Of 5-6 ESC's I've sent in to them and 2 motors, I've not paid a penny, and in some cases have come out better off (one time the motor was upgraded to the next model, the other motor was over 1yr old with countless runs on, on varying voltages, eventually the windings become damaged, I sent it in expecting to pay some towards a replacement, new replacement pre-soldered for me with free decals arrived in the post a couple of days later, at no cost).

Anyway enough rambling, back to work :)

[tcolesen]

I believe Tcolesen on these boards sent one in from the US and the total turnaround was approx 10 days?

I forget exactly how long it took, but it was in the range of 10-14 days. That's fast service considering that BK (Germany) has taken 4 and 6 months for two separate repairs and MGM (Czech Republic) took 6 months.

[hivemind]

i think its great you are happy with them and they no doubt take care of their people who buy thier products. in answer to your question the only three times in just over 11 yrs. i have had to send in any of my novak stuff (one xxl rec. and one superrooster and one xrs) they got my stuff back average 8 to ten days US. as far as the european dis. i don't know. but despite beating the crap out of my novak goodies to be honest if you pay attention to their recommendations they just don't break down so the 120 days from purchase is more than enough for me. and, in addition when i e-mail them they e-mail me next day to tell me what went wrong. (dang puddle!) it's plain to see that both companies take care of there people and know how to protect there future bussiness. it's good that we are both happy with our respective choises.

[Rtsbasic]

And it can only get better as more and more respected companies jump on the brushless/lipo waggon. Castle Creations have impressed me and I've only owned a Mamba 25 so far. Orion are giving it another go, and rumor had it another UK company was considering it (MRT maybe? dunno).

[hivemind]

castle creations i'm not to familiar with. i've seen some of thier stuff but didn't get a close look. the mambas seem to be pretty powerful. got any info?

[neweuser]

If you're looking to go Brushless, go to RCMonster.com! I would not use a castlecreations in a maxx. Not that there are not good, they are great. But taking the weight of one to the level you need, it's not very dependable IMO. You can get a 9920/9xl feigo c xl that is for about 300.00. And for the extra 50.00, well worth it. HV Maxx? i have ran three in total and have had nothing but heat issues in my maxx. Also, RC Monst Mike is a great guy with great customer service. It took Novak 6 weeks to exchange each HV system i had, and i only live in MN. Plus they said that i never sent the warranty stuff with the unit. Good thing i kept copies of everything. So, with all that said. 9920/feigo c xl motor would push very nicely for the $$$$$$$

[Dan-o]

I'm in MN as well. from Eagan, a reformed Hobby Zone racer.

[neweuser]

Wooo hoooo! A Minnesotan! I need to find a track to race. Any suggestions?

[gixxer]

Don't forget to mod your emaxx. The BL chew up the plastic idler gear in a couple of batteries.

Mods i recommend in order. Of course you will need to run the correct pinion gear.

1. Metal Idler gear. http://www.unlimitedengineering.com/cgi-bin/store/13407.html
2. Rear Mip CVD.
3. Front Mip Cvd.
4. Kimburg spur gear
5. Center cvd.

[Dan-o]

gixxer...two steps ahead of you...Thanks though!

New E User...I'm planning on running with the Team Extreme guys this winter...they run out of the Rosemount VFW and do various events around the state. where are you located? I'm in Eagan.

[neweuser]

St. Louis Park. You are a tad away. Is there a closer track to me do you think? I thought there was one in Brokklyn Park, but i heard they shut down?

[JakeE]

TCHR (Twin City Hobby and Raceway) was the track in Brooklyn Park. That track shut down on June 15th of this year. Currently the only tracks around, to the best of my knowledge at least, are on-road parking lot racing put on by some of the local hobby shops.

[neweuser]

That is really too bad. Maybe I'll purchase a plot of land and get something going! Really all you need is..land, transponders, computer software, whole lotta dirt and a bobcat! Some knowledge would help, but making a track would come with practice!

[glassdoctor]

If the maxx is stock (lightweight plastic... not a bunch of alum) and you can gear it low enough the Mamba may actually work pretty sweet. If there was a lower kv motor option I would say I'm sure it would work.

More details later but I'm testing the MM (just the esc, with a different brand motor)in a 1/8 buggy and truggy, and so far I' have been impressed.

[neweuser]

Well, in the maxx, speed with BL + lots of plastic=damage! I run the gmaxx, with Quark 125b/9xl with 5s lipo...so it's juiced pretty good! it weighs around 10-11lbs with the lipo....my girl has a stock emaxx, all plastic and hers is around 13-14lbs...
