Good BL System

[BrianG]

Yes, get a UBEC for anything 3s or more!

TBH, I think you'd be happier with lipos if you can swing it. I don't think I've seen any NiMH cells that can provide the current AND voltage BL systems can pull... not without stressing them anyway.

Just to play devils advocate for a minute I would say that the HV 6.5 system is a good reliable turnkey setup for a Maxx.

It may not go 45 mph but we're talking about an E-Maxx here right?

It trips me out to see guys setting up a "Monster Truck" like a race car. If you want to go that fast you should put that Neu or Fieago system in a buggy. It would go faster and handle better.

I have a HV 6.5 in my maxx but it's made for bashing and running over stuff. It has all the power that the terrain I like to run on can handle.

If I put it on the street I can see where you might want a little more juice. But for off road, it has plenty of power.

ok thanks for the info guys!!

another Q, would the MM and 8xl be so much powr that i need stronger diffs?

i forgot to sayi dont want a system thatll rip my stock maxx in one run

but dont worry, im going t odo a complete 3.3 conversion

Don't be surprised when your diffs prove to be the weak link in the drive train, even 3.3 diffs won't last. At least shim them properly and put the diffs in some cheapie metal diff cases so they can't twist under accel. That might make them last a little longer.

OS 18TM was enough to shred my 2.5 rear diff repeatedly and the 8xl should deliver more torque than that. The difference in the 3.3 diff was 2 extra screws in the stock plastic diff case so it had 4 vs the 2 screws the 2.5 stock diff case had. Was some better, but not strong enough, it can still twist enough to let R&P strip.

Dont forget, he said he has a $300 limit. I dont think you can get a full set up (motor/esc/UBEC/gears/heatsink) for under 300 unless you go with Novak. I'd also recommend a 4.5 instead of the 6.5. Its a little faster. IMHO, the Novak systems are great plug and play systems. No, your not going to be the fastest on the block, but they should be reliable systems that will hold up over the long run. 45MPH in a maxx is probably not going to happen, especially if you dont pop for lipo's. But you probably wont hit that with the systems mentioned above without lipo's either.
