outrunner'd e-revo
 

I just ran my revo for about 10 minutes keeping an eye on the temps.
I am running the 2826-8 axi outrunner motor on 2x2s 5000mah 20c packs,and a mm.
The motor got up to 180,and there is some cogging if i hit the brakes to turn and then hit the throttle without stopping,but I can work the throttle with no issue's as long as i don't hit the brakes.is there anything i can do to fix this or is it par for the course running an outrunner on the mm?
as long as i didn't use the brakes,i could accelerate hard multiple times and top speed runs,the motor run about 130.
Is it common for the motor to heat up using the brakes?
here are a couple pics.
I have the motor geared 22/40.the esc and batt's temp 100-110 degrees

Looks like a really cool setup. Yes, using motor brakes = more heat. About the cogging, I'm not sure. I'd think you could tame it. Have you messed with the MM settings at all ? Perhaps try increasing the timing and start power. I think with higher pole count you will need the increase in timing. Not sure if start power will have any effect on your situation, but it could.

My E maxx setup doesn't cog at all. I'm sure this is something in the settings or something.

Are you sure you have the latest edition of the firmware for the MM?

1.17 firmware
50% brake and reverse
0% punch control and drag brake
high start power and high timing(15)
1.5sec arming time 12v cutoff
that is how it is currently setup

22/40 gearing

You did go to the Castlelink software and click on the Software tab, and then choose "Update Firmware"? This sends the updated firmware to the controller. Just making sure with this step. It's very important.

You might try some punch control, but the most important thing you can do at this point in the setup, is broaden your neutral band for the controller.

Throttle Dead Band - change to Large

What is the little Red box I'm seeing in your setup?

Lojack for rc cars. Just in case it gets stolen... :yipi:

It is a personal transponder for racing!

And make sure that you check your gear mesh. Make sure it is not too tight at one spot on the spur. Do you have the fan upgrade on the 2826?

:lol::lol::lol::lol::lol::lol:

I do have the fan on the axi,I will change the throttle deadband.
Should I move the timing to the highest setting from high?
The gear mesh is good,I make sure to check it in multiple spots.I learned that lesson the hard way years ago:yes:

Thanks again for the help,
Kevin

I checked again,in the current firmware box,the castlelink says v1.17
I checked for updates,none newer than 1.17 that my castlelink can find.

Try highest timing and see if it helps.

Yes try highest.

Outrunners like alot of advance when it comes to timing.

I can't remember if I had mine set on high or highest, but it worked flawlessly.

What do you think of the performance from such a small motor?

lots of torque,had the neighbors freaking out.
no way to radar,but I would guess the top speed to be around 35 mph,is that what you were getting out of the axi in the emaxx?
I moved the throttle deadband(what exactly does it do?),and have the timing on the highest setting now.will try it this weekend at the track.

I am happy with the performance,does exactly what I wanted.more efficient setup with more topend.I think it will be real good on our track

The Throttle Deadband is how wide the Neutral setting is on the radio trigger.

Yes, top end was around 35mph. But this setup accelerates pretty hard!

You should be seeing increased runtimes over your previous setup. I was getting about 25 minutes of runtime on 5000mah 4S setup.

I did try this on 5S. It screams!, but heats up very quickly. 5S is too much to keep temps under control.

I definately see the increased torque.lift the wheels at will on the pavement.the acceleration is much improved,the truck seems to handle it very well.
I scrubbed the wing up pretty good on the road with the wheelies.
I was out for 10-12 min and the battery's combines had 14.5 volts still.
I was happy about that.

I got a chance to run this setup with a couple of buddies of mine.

One of my friends had a stock E maxx 3905.
The other had a T maxx 2.5.

This of course pretty much smoked the stock E maxx, but to my surprise it also outran the T maxx.

It took the T maxx pretty badly on acceleration, but would also outrun it on top end. At least for the first half of the pack.

During the last half of the pack, top end was a VERY close match. I could still out accelerate him though.

great,good stuff.
I'll get to race with the nitro's in the morning.
Can't wait to get some lap times,see how much better they are(if any)
