BL set-up help
 

I know that this question is propably getting old, but I'm gonna ask anyway. I am looking for a BL set up for around $350 For my e-maxx 3906 (yeah I know I should have bought the 3905).Ive already gotten all of the required drivetrain parts. I would like to be able to run the 14 cells I've got now and still be able to switch to lipo's in the future Ive dumped about 1300 dollars into this beast beefin it up and now I think its ready for a good boost in raw power. Heres the kicker I am in Iraq and need to be able to have the system shipped to an Apo, Ae address. Any help would be greatly appreciated. This forum is awesome and I look forward to sharing my bashing, racing, and breaking stories with you all. Thanx

I would recommond a mamba max esc and a 9xl motor for your maxx, and that would give you about 100 bucks left over to spend on batteries.

Upgrades/hopups.
 

You can get merchandise shipped to an APO from Tower Hobbies. They carry the Mamba Maxx system, and the Novak line of brushless systems as well. I am willing to bet that you will find something to work for you at theri site.:lol:

Your budget of $350 is possible... maybe. What speeds are you looking for? Higher speed (over 40mph) is gonna need power and the MM can't handle the voltage or current for really high power/speed systems. That kind of stuff can get expensive.

For a budget system, the MM ESC and a 8XL or 9XL would be the thing like Gmaxx said. Watch temps and gear appropriately.

However, you are already running 14 cells. The newer batches of the MM will only run up to 12 cells. But, some people are saying it handles more voltage after the newest firmware update. You might want to check more into this. 4s lipo is ok though either way.

Ive checked out the Novak HV High-Voltage Brushless System 4.5. Has anyone tried this and if so what did you think? I could probably dump a couple more $ if I had to but trying not to. As far as speed, Going 40+ I'm not gonna lie I'd like that but not enough to set a couple hundred bills on fire. I guess I am interested in a system that will handle some abuse be quicker off the line and have a longer run time in between battery changes. I think the lipo switch will have to come sooner.

Hopefully this helps some:

Novak systems which are easy "plug and play". These are sensored motors and will have no cogging. Being a smaller motor they compensate for lack of torque with a higher KV. Higher KV motors tend to run hotter. With the higher KV there are greater RPMs per volt, and as such you need to gear down much more, which generates the torque. Most other BL motors have a larger magnet which generates more torque, so you don’t need to gear down as much.

There are two motors which work well with the E-Maxx: the HV 6.5 which is better for bashing and the HV 4.5 which is better for racing. The 4.5 will have more top end. On 4s the speed controller may run hot and require some type of cooling such as a fan, body vents or heat sinks. I found one reference for the 4.5 of 750 watts of power and 40 oz of torque.

These motors will come packaged with a speed controller and are more economical.

2. Feigao motors will have more torque than the Novak motors but can also run hot. Again, because of this inefficiency they may need cooling modifications such as fans, vents, heat sinks. The end bells are pressed on and may require a clamp to prevent failure. There are three motors which work well with an E-Maxx. The 8 XL on 4s, the 9 XL on 5s, and the 10 XL on 6s. I found one reference for the 9XL of 52 oz of torque.

These motors run well with a Mamba Max speed controller. The MM esc is programmable and has more setup options then the Novak and therefore it gives you greater control. However, above 3s it will require a battery elimination circuit or bec.

im running a mamba max with a feigao 8xl and 4cell and im very happy,much better than stock thats for sure well worth it.:yipi:

Well I've done some research, and I decided with the Novak HV 4.5 set-up. Now to find the cheapest site.

No offense to the ladies, but I feel like a chick (I just changed my mind). I do believe I am going with what Gorillamaxx360 recommended.....I think. still researching

If you want Novak, I'd personally go with the 6.5. From what I've read, the 4.5 seems a bit sensitive to gearing.

Still, with the choices being the Novak vs a MM/FeigaoXL combo, I'd go with the latter.

for the risk of sounding well...dumb the MM your talking about is the Castle Creations Mamba Max ESC, correct? I'm checkin one out on monster as we speak

Yup, MM=Mamba Max ESC.

Thanks BrianG, I think I'm going to purchase the set-up here in the next hour or so. do you know of a good site, that will have everything I need?

And I did pick up on the emphasized "M" in Mamba and Max I just wanted to make sure there wasn't a Wierd alphanumeric code or nomenclature I needed to be aware of.

lol, no, no code. Most of the abbreviations are pretty straightforward. :smile:
