60 mph mamba brushless setup for e-maxx, would this work?

I havn't done dual in a long time, but I'll throw this out there..

I had two Lehner Basic 5300's on 12 cells each in my hyper7 buggy..
I later went to a single Hacker B50 8s on 16 cells, and the power was about the same, cost less, and weighed less..
I know those aren't very good examples, as both were out of the rpm spec, but from my experience, you're better off with one motor, than two less powerfull motors.

After reading the responses, I have made a major change of plans. I will be doing a single brushless system. I will be using the fastlane machine chassis with 16 cells (2 8 cell flat packs in side by side format). I will use the wanderer 8XL. I would still like to use the mamba maxx esc. I also would like to use the supermaxx differentials. Will these differentials work with the fastlane machine chassis and the driveshaft it comes with?

Now we're talkin'! :) However, I think (personally) that running 16 cells on one MM is really pushing the limits. They way to efficiency on a MM system is voltage, and yes, 16 cells is a good idea....but the reliability of the MM ESC at 16 cells is questionable. Some folks have no problem, others smoke 'em. I think it's just the luck of the draw and manufacturing variances. I'd go for a purpose-built ESC at that point (Quark).

I'm not too sure about the 8XL either. I don't think I'd go lower than a 9XL, and I'd most likely use a 10XL. Generally the larger the truck, the lower KV you want. You gain speed by gearing it up and adding voltage. You are already past the limit on voltage, so your only solution is gearing. This is why a different ESC is needed. Getting to 60 MPH takes a LOT of power, and I'm not sure if the MM will deliver reliably for you.

Would the Warrior 9920 work or would I need the Warrior 12020. Where can I get them and how much do they cost?

I already did this 8mos ago w/ my BL Revo. You will get ~45mph w/ the 8XL on 16cells.

Now this is alot of power, and its very fun to drive, but if your big/only goal is to do 60, then you need to ~2x the power. On 5s Lipo/8Xl/MM i did 48-49 mph reliabiably. My conversion parts were light, but this was a stock 2.5 chassis and talons. Dropping weight I could see 50-51 I'm sure. This is the very edge of what a MM can do.

To get to 60, I would say you need ~2500+W for an avg/light Maxx. My 5S setup was ~1800W realisticially. As speed goes up, each increase in power shows diminishing results.

You will need an expensive drivetrain to do this as well. G/l trying to keep the front down. The MM cannot provide enough power unless you get your truck to insanely light weight (~7.5 or less I would think, but just a guess.)

An MGM/Neu may do it. I would try to run as much voltage as possible with a low kv motor and gear tall.

This is not a budget project btw. Face up to spending the $$, or realign your goals w/ your budget.

Making a 60mph truck does not make sense for bashing either. Dragsters do not make good daily drivers. Low 40s is plenty for bashing. Trust us, we've done it, we know. I barely even run my 5S batts, and that's only on the street for speed runs. Even 35 is fast on rough bashing sites like contruction lots.

Johnnymaxxima used 2 7XL motors on 5s lipo to each. Would the same motors with 16 cells to each, full metal transmission, supermaxx differentials, and MIP cvds geared 24/51 be a setup to reach 60? I really do not have the money to get lithium. Is the extended center driveshaft that comes with the Fastlane Machine chassis compatible with supermaxx differentials?
