New Brushless EMaxx

[tuclai]

Hey Guys,

I am looking for some info and advice. I will be picking up an EMaxx tomorrow and will be converting it to brushless/lipo setup. I want a fast for bashing/track and a reliable setup. What do you guys know will be the way to go? I know there are a lot of systems out there. I still have an extra MMM v3 sitting around that I can use to, but dont have to since I like having an extra one as a backup to my truggy and buggy.

I want fast but very reliable, any suggestions? Also, let me know if there is anything I need to do with the stock EMaxx setup out of the box before converting.

When you find that, I will bow to you.

Right now there is the large scale Losi, the MMM, the Quark Monster Pro and a few other very expensive units. All have failed, but I believe the Quark is one of the most reliable units. I would personally run very far away from an MMM in fear of getting freshly exploded LiPo juice on me but there is some success with this ESC(you know, you own them). From my limited, albeit instensive experience I actually had more success running dual VXL systems than anyone in my local area running singles. It was a very reliable system for me. On 3s it will run 50+ and stay cool. And it just sounds cool. The motor is going to depend on the battery you plan on using. Unfortunately the Maxx trucks don't give you a ton of options on LiPo packs due to the funky offset motor plate. I believe somewhere around 3s 6Ah is about the biggest pack you can get under the lower side of the motor plate. What battery power are you looking for? Many people have been running the MM/7,8,9XL on 4s LiPo and it has proven very reliable at the expense of some speed. Look at about 40mph on a properly set-up MM/8XL on 4s. Plenty fast for an E-Maxx and enough torque to launch into a backflip. Honestly the 3905 doesn't need many driveline upgrades to make it near bullitproof. I would add aluminum diff cups because I shread mine quite often, but some people don't have that problem. If you will spare the MMMM you have and go for the Neu motor of your choice then you will have about the best set-up you can get, barring the MMM stays in one piece. You are going to want to upgrade the shocks right away if you are planning on racing or doing any serious bashing. The weak little shock shafts bend under light pressure and the plastic caps tend to blow after huge jumps.

Whats wrong with Novak HV system? I noticed Novak has used the EMaxx for testing with their HV system. The only reason I would give Novak an option is one, I have a HV 6.5 on my Kyosho Inferno GT that I convereted to electric. It runs great be it only an on raod. But, about 40MPH and really cool and reliable when bashing around the parking lot. And the second reason, probably most important is they are right down the street from me. If anything goes wrong I can get a replacement unit same day, vs waiting a month for MMM + NEU setup.

Do you guys know anything bad about the Novak HV? I am considering the HV 5.5, as I hear from Novak the 4.5 may be a little unreliable.

[Tempted]

The Novak HV has woprked for many and overheated for just as many. You will have extremely limited gearing options. The 4.5 will overheat in the E-Maxx 90% of the time.

I will be going with MMM v3 with NEU 1515 1.5d. I will be using 2 4s lipos 5000 mah in parallel. Any advice on what pinoin size i should start with?

[BL_RV0]

If you haven't ordered the motor already, get a 1y instead of the 1.5d. Just gear up a little...

[tuclai]

I already got the 1515 1.5d for my Losi 8ight Truggy. I am using a MMM v3 with it on 4s and works great. After doing some research I figure it would be better to use a 1515 1y on the 8ight T and use the 1515 1.5d on the EMaxx. This is why Im getting a 1515 1y, so I can use it on my 8ight T and use the 1515 1.5d that I have right no on the EMaxx instead. I also have a 1512 2.5d with MMM v3 on 4s lipo on a Losi 8ight Buggy and its been like a champ too.

I've run two 4.5's, one in an E-maxx and one in a converted Revo. Both worked great. Most people that have overheating issues have it geared wrong (yes, I said MOST, not all). Yes, gear options are "limited", BUT why would you need to change it from the optimum gearing?
To me, the only down side to the HV is the limit of 4S. But you stated that you are shooting for a 40MPH top speed, which is right in the HV 4.5's range, and maybe the 5.5's.
I currently run a MMM/Neu 1515 2.5d, and on 6S it is really too fast for anything but showing off. I'd gear it down, but I'm physically out of room on the 3906 tranny/motor mount.

I am going to disagree with Tempted that Quarks are one of the most reliable. Alot of people have reported that they tend to go Super Nova. The MMM V3 is a good choice. The MGM controllers are also very reliable albeit pricey. I like the 1y for bashing.

These are great but pricey and if I remember correctly it is very hard to get warranty issues resolved. I don't own a Quark but from what I understand the Monster Pro is a nice piece. But once again I believe it is very hard to have a warranty claim solved. My only personal experience are with the usual MM, MMM, V-Twin and Associated(small) systems. The MM seems to be the more reliable of the bunch, the V-Twin the best bang for the buck and the MMM(only V1 and V2) the worst in terms of reliability. The LRP systems are too small for a Maxx but awsome in a buggy and ST.

Edit- Any good, solid info on the large scale Losi system yet?

I got my EMaxx today, hopped it up with RPM Rear True Track suspension, RMP front arms and Big Bore aluminum shocks. I have decided on MMM v3 w/ NEU 1515 1.5d on NEU 4s. I will be using two NEU 4s 5000 mah in a parallel configuration, so 10,000 mah!

You guys know if there is a single servo configuration for EMaxx? I got two spare Hitech 5995tg to use if I have to stick with the dual, just think 700 oz of torque is a bit of an overkill!

I should be getting my motor and motor plates tomorrow, so cant wait to see it in action.

Responding to Losi Xcelerion 8th scale. They are ok, but my buddies have only used it in Losi 8ight scale buggies and truggies. They have random dead ESC/motors, but the good thing is Losi is down the street so its a just a matter of giving them the car and getting new ESC/Motor within a few minutes.

The 1.5d works fine for me in the erevo. You choice of the 2 5000 packs in parallel sounds like a good idea. My truck geared for 43mph pull a set of trakpower lipos hard, and I have a pair of 3700 4s packs to run in parallel. Should help with the amp draw.

...which is the problem with MGM, being in Europe, when warranty work is needed it can be a bitch.

You should be able to just ditch the second servo and accompanying hardware. I'm pretty sure you can run a single servo on the stock pieces. Overkill? What does that mean? I say put two of those servos on for steering and then option for the 2 speed and use one more there!(sarcasm)

I've been involved in the discussion before on 2 packs in parallel vs a single pack. From what I learned in those, there is really no benefit in running both packs. Wouldn't a single Neu provide enough amperage for this set up, and be a lighter load?
