E-Maxx Outrunner - RC-Monster Forums

ilpufxit · **E-Maxx Outrunner -** 12.05.2007, 07:47 PM

I bought one of the Outrunner setups on E-bay a while back. Before I ordered it, I called Castle Creations and asked them if I could run the outrunner with my MM controller. The tech said no problem, I might just get a little cogging (I don't want to see what a lot looks like) but there will be a software update later this month (June, I think). Of course the update still hasn't been completed and I just now finally got a Quark 80b to run the thing. Sure enough, the day the Quark arrived we got snow so I'm still waiting to really test it out.
These are some early pics from back in June. I'll get some new ones up later.

Check this guy out "sikeston34m"

He made the conversion and sold it to you. He could answer any questions you have.
By the way Welcome to the forums!!!

sikeston34m · 12.05.2007, 08:47 PM

Did someone mention my name?

Yes Welcome to the Forums.

Sure, I'll answer any questions that you might have, and yes, I thought that looked familiar.

I tried this setup on the Mamba Max also. It doesn't get along with it at all. I also contacted Castle and asked them if it would work BEFORE I bought the Mamba Max, they also told me that it would work. No Go!

The Quark handles this setup VERY well and even larger outrunner motors than this.

Please check out my "Direct Drive to Diff Revo Conversion" thread here in the Brushless thread. You might find it interesting as well.

Just giving credit where its due!!!

That outrunner is torquey enough to run just 6 cells? or did you just take a pic with only 6 and not 12?

sikeston34m · 12.06.2007, 06:32 PM

It will run on just 6 cells, but the top speed isn't there.

Much better on 4S Lipo.

Those are build pics. I did actually try running 18 cells nimh. Amazingly my MM esc didn't blow up and I did get some good top end but it wouldn't start without a push. However, not much torque and I was thermalling within 5-6 min on short grass. It currently has 2 Maxamps 2s 6000 packs and a Quark 80b. I only wish we didn't have this snow so I could do some speed testing. I'll be adding some updated pics tonight.

The MM doesn't know how to handle this setup. All I got was stutter, stutter, Cog, thermal shutdown...........

The Quark on the other hand, with those Lipo's.

I would like to hear what you think when the weather gets good enough for you to try it with the new setup.

I've added the latest pics of the E-Maxx. Not that its really all that different, it just works now. Unfortunately more snow tonight, sigh.

In the meantime, I'll be working on my new projects;

Cool. It would be nice to see some proper feedback about how well this setup actually works. Not that I dont trust Sike, but its always interesting to see other peoples experiences.

I'm with you on that one Neil.

We need some feedback, some unbiased feedback. Pro's and Con's. What's good about it? What's bad about it? The whole nine yards.

Your feelings on runtimes and temps. Anything that you want to say.

ilpufxit · **Wheel time! -** 12.10.2007, 12:56 PM

I found a dry parking lot last night for some testing. Too dark to get any video unfortunately. I ran the E-Maxx with 2x 2s6000mah MaxAmps packs, near fully charged. I'm still getting cogging on startup, especially in 2nd gear I have to start very slowly. Once rolling it pulls well. Looks like 35 - 40 MPH to me. I tried a couple times to pull rolling wheelies, it was having none of it. Decent acceleration but it really didn't seem to have the torque I was expecting. I'll try playing with the controller settings, I'm not really familiar with the Quark yet. No doubt it would be faster on 6s but so far I only have one 3s pack and I've been warned

about more toy shopping before Christmas.

Ummmm, something isn't set right.

Set the Quark to these settings:

Battery Selection: Manual
Lipo Cutoff: 3.0 volts per cell
Motor Type Selection: Inrunner
Torque Selection: Dynamic Initial Torque

If you still experience cogging with these settings, increase the Neutral Range one step.

These are the settings in the setup that REALLY affect how the motor runs. The other settings are entirely up to you.

On Battery Selection, if you have it set to anything other than "Lipoly High" or "Manual", the quark will limit the current it feeds to the motor thinking that it's protecting your batteries by not drawing too many amps. Your Lipo's are up to this task for sure.

Motor Type Selection. I know the Quark has an "outrunner" setting, but the inrunner setting works MUCH better.

Torque Selection: Anything other than Dynamic Initial Torque is like "Soft Start". Low starting power will cog alot on take off.

Please use these settings and let me know how it works.

ilpufxit · **That's better! -** 12.11.2007, 09:52 AM

I'm sure it was the dynamic torque setting that was wrong. The default is soft start. Now its got good power, more like what I was expecting. Still getting some cogging from a dead stop but much more driveable. Pulled a few wheelies. Stopped running when I dropped a driveshaft pin and lost my rear drive. Now that it works I'll go through and loctite everything.

Thanks for the help, I'll get some video up asap.

A nice simple & cheap replacement is to use a T-maxx chassis:

Its much stronger than the stock plastic item, and very cheap- just requires about 4 holes to be drilled for velcro battery straps or whatever. Other than that, the FLM chassis is nice and very durable too.
