Looking for input for BL set up for Emaxx

[jpoprock]

Hey guys... I've been wanting to go BL for some time now in my 3905 Emaxx, but was waiting for the right opportunity. I lost a 540 Titan in my 3906 Emaxx the other day, and it got me thinking. I run a Spectrum DSX3.0 radio, and use the EVX-2 in both Emaxx trucks. I could put the 550's from the 3905 in the 3906 and run those till they die. That 3906 is just my "bash around when I'm board at work" truck anyway. My 3905 is my baby. And so maybe I should just take the plunge and go BL on that truck. I love my PedeVXL, and use a 3c Lipo on that one. I'll have to buy either one good 4c battery or maybe two 3c and wire them in series if I go BL.

But my question is... there are so many options for BL that it makes your head spin. The new Mamba 2200v system is great and all, but really expensive. Surely there is a more affordable Mamba system that will be perfect for just backyard bashing (no racing). I gear my truck 66T/19T right now, which is stock. I would be happy to experiement though.

I hear the Novak BL systems have high temp problems over the Mamba. But Mike sells some other motors and ESC's that I'm not real familiar with. So I was looking for some input.

Thanks!

You can get buy with a mamba max (with mods) and a cheap brushless motor, but usually keeping it withen allowable temps can he a hassle. for the most part the MMM combo is the most cost effective solution once you factor in customer service, performance and price.

yeah $279 for a 6s esc all wired up and a fat 2200 neu~ish motor not to mention the cute green pinion LOL it really is your best option. A feigao/clamp/mm/bec will run you the same yet be 1/4 the thrill

Cheapest setup that should perform pretty well:

Medusa 36-60-2000

Hobbywing 80A ESC

That is exactly what I am about to put in my FLM/ RPM rustler with a Zippy H4000mAh 25 - 35 C pack. I'll be sure to let everyone know how it goes. I'm expecting barely (if at all) controlable.

I have no doubt that new Mamba 2200kv is the bomb, and will work great. That Medusa/Hobbywing ESC seems nice too though. Affordable. Wonder how the temps would be on an Emaxx? I'm assuming a good 4c Lipo would be the way to go, or two 2c in series?

[suicideneil]

2s - the 's' stands for the number of cells in 'series' inside a pack; 'c' along with a number (25c for example) is the discharge rating.

Anyway, a pair of good 2s lipos in series would be best to fit the 3905 ( I said good, not maxmaps...). If cheap and cheerful is your thing, then look into the Zippy items from hobby city, or the SMC lipos, or the TrueRC lipos even.

My advice is that if you can't afford $280 right now then either start saving or find a new hobby! The Novak system isn't horrible and would be controlable for someone new to brushless but the price is about the same as the MMM combo. The old saying "you get what you pay for" really does apply here! At the very least get a good motor, a cc/neu, neu, Tekno neu, or Medusa. Stay away from the lower end motors, you'll need a RC-M heatsink clamp to keep it together and keep temps in check and at the price of the motor and clamp you might as well get a good motor for $10-20 more. The hobbywing esc might be ok if you keep gearing reasonable but again you might as well get something that will serve you well now and into the future! The Mamba Monster combo is going to be a torque monster so if your looking for a little less torque the Mamba Monster and a Medusa 36-60-2000 or a 36-70-2000 would be good choices as well. The 60mm version should be good for speeds of 35-40 and still have decent temps, the 70mm will be cooler and could take a little more gearing and get you over 40MPH. Of course this is all just my opinion but most here I beleive are and will say close to the same thing.

Just get the Mamba Monster. It may be expensive, but its worth it. I had a hobbywing controller, but it was not reliable at all. Just do yourself a favor and get the Monster combo.

As for batteries, these would be great for a 4s setup, but they are currently out of stock. Zippy 5000mah 2s 20-30c-http://www.hobbycity.com/hobbycity/s...0mAh_2S1P_20C_

I use these, they are great and run really well with the Monster combo.

Hope it helps.

I agree on the MMM controller. For what you get its a really good price on the combo. The ability to program on your computer is just huge for these types of vehicles. It could save you on broken parts down the road. Things like adjusting brakes, punch control, lipo cutoff etc etc are all invaluable when running these trucks especially when you get into the 35mph to 40mph range and beyond.

I have an MMM feigao 7xl combo which used to be MM 7xl combo and also an MMM 2200 combo both in 2 3905 emaxxes. I like the 7xl but you are limited on runtime as the motor will heat up and there is the constant worrying about the can popping issue. Even when using an MM you need the external bec and by the time you get that and the rcm heatsink you might as well just buy the MMM combo.

The 80A esc might be a good way to go to save some money but I dont personally think 80A is enough for an MT. I fried my 80A mtroniks truck esc on the 7xl geared for 38mph. I know some of the guys have been testing them though so they might want to chime in on this one.

Well, I don't want to give the impression that I'm completely clueless here. I'm sorta "new", but the vast amounts I have learned in a year's time has been staggering. My problem is that I kinda have too many vehicles. I can't make up my mind on exactly what I want. I want them ALL! I have a PedeVXL that is hopped to the max, and I just love that thing. But it's not quite big enuff to be my "only" truck. So, I have a 3906 and a 3905. I got the 3905 thinking I'd sell the 3906, but I never did. I get a kick out of that 3906 for some reason. I always feel it's slightly faster than my 3905. Might be a little lighter though. I don't really run it in high gear much, as all the fun happens in low. Besides, I don't feel like it gets any faster in high gear vs low anyway. Unless I have i backwards. See.... it's the little details that I tend to not pay attn to. Like typing 2c instead of 2s.

I don't need to set a land speed record w/ my Emaxx. I'd consider selling the 3906 to pay for some upgrades. But it's just really expensive when you own so many vehicles. My best bet would be to have my PedeVXL, which is fully hopped, and my fully hopped (but w/ stock chassis) 3905 converted to BL. I have a Jato too, but I may sell it after this summer, cuz I can only really use it half of the year and my Pede is just as fast if not faster. But oh.. that nitro sound!

Anyway... I don't really need an Emaxx that will hit 40mph. What I'm really wanting is better run times. My truck is heavier now, and it eats my batteries for a snack. I get sick of burning thru two packs every 10min. I hate it actually. Just as I get into the groove, I'm changing packs. I would be more than happy having the same or better stock speed and torque, but with longer run times. In order to do that, I'm going to have to buy some Lipos or maybe some A123. But then what does that mean for my stock EVX-2 and Titans?? Those should probl go too huh? So... to get better run times means that I need to spend $500? HA! That just can't be.

Maybe if I dump my Jato and my 3906, I can buy the MMM 2200. I dunno. I didn't want to have to do it all in one big jump. I was hoping to enjoy longer run times first, then convert to BL when I needed to, or wanted to.

So there it is fellas. I just want my truck to run for 30min rather than 10!

Here is a pic of my truck:

UE arms, GArc bulks, Supershocks, Alum buckles, Ti pins.

FWIW.... I think that whenever I do go BL, I'm just going to get the MMM Combo and be done with it. But to do that AND buy at least two Lipo packs, is $$$ all at once. Unless the MMM will run ok on my paltry collection of 3300mah 6 cells x 8, 4600 EP 6 cells x2, cheap 4200 cells that used to build two 7 cell flat packs.

I kinda envision myself back in my high school cafeteria, standing in my underwear, with the MMM combo laffing and pointing at me.

Sell the 3906 and buy the MMM/2200 combo. Run on 4s to put a smile on your face and 6s for the big ear to ear stupid grin.

There are cheaper setups, but by the time you get them set up right to run an e-maxx, you have almost spent what the MMM combo costs in the first place.

[E-Revonut]

If you get the MMM combo and gear it real low, around 25MPH (stock speed), you should be able to get away with your nickel packs for now. Runtimes will be a bit better as it's more efficient. As soon as you can I'd get some lipo packs, and if your current charger isn't lipo capable you'll need a new charger as well.

[jpoprock]

I have an Onyx 230, so I can charge one pack at a time. I'd probl pick up another one though. I might pick up a set of stock Titans and throw them in the truck to help it sell. It's a really nice truck. RPM arms all around, FLM rear diff cup w/ shims, plus... I could throw my HCR chassis on it to up the price even more, or sell it by itself. Factor that chassis into the deal, and I could probl get more than enuff to buy the MMM Combo. Once HobbyCity gets those Zippy's back in stock, I'll get four of them for that price! $30 a pop? Wow! But they are down like -136! Could be a long wait on those! But there are other "cheap" lipos to get. Better get a Lipo sack just in case though!
