As motors go, are we better off with a fast motor like a Feigao 6XL in an E-Revo, or are we better off going with a higher wind to get more torque like a 10XL?? I can't afford a Neu.

Also, anybody tried a Novak brushless setup in one of the new E-Revos??

Hi Soldier,

I've been thinking about giving the Medusa Motors a shot myself. I want the 036-060-2000V2.

Set your ESC to Race Mode, Dynamic Torque, Inrunner Mode (seems to work better even with multipole motors), Normal Braking

In my opinion, you are undergeared.

In Mod 1 gearing with that motor I would go 14/40.

If you're going with the 32 pitch gearing, you probably need a smaller spur and a larger pinion.

You might also try a heat sink with a fan if you're worried about temps.

I've heard those motors are pretty mean. :yes:

The faster kv motors like the 6xl tend to be less effecient and heat up more than a lower kv motor does.

Longer runtimes and lower operating temps come from higher voltage setups with motors such as the 10xl.

Gearing means alot too. :yes:

Check your radio setting, and make sure that you zero out the throttle channel adjustments before you program it. I run a 1500kv 60mm v2 in my hyper8 on 6s thru a 125b and it works fine. I do need to turn down the brake force though...

They are supposed to come out with a 70mm can model. That should compete directly with the cc neu motors, price-wise. I will most likely try out both when they come out. I want a low kv long rotor motor to replace the 14xl in my savage. I have a mega 22/45 motor that I need t try.

Too many toys...

Thanks for the advice guys! I can't wait to try the new settings in my ESC! :yipi:

A little video of my E-Revo 6s
 

looks good. I am running a 1515 3d and have mine geared 17/40 right now with 0 degree's timing and 60 or 70 percent punch control. Trying to tame it down as much as I could.

a lower kv and higher voltage system will be more efficient, run cooler but will be more expensive than a higher kv and lower voltage sysytem...it will depends on your budget

Quark on Fire!!
 

OK,
I tried the suggested changes to my speed controller settings on the Quark Monster 125, but they didn't seem to help the cogging. The only setting that seemed to help was setting the Neutral range to "wide". But still there was too much cogging when transitioning from coasting to throttle...in fact the wheels would lock up momentarily when transitioning from coasting to forward throttle.

I switched out the Medusa and put in my old Feigao 9L. It was much smoother...BUT:
I ran it at 6s for about 60 seconds in a parking lot. While braking from a full-throttle run, the Quark Monster 125 caught on fire!!:surprised:

I quickly removed the body and stamped out the fire trying to save my expensive batteries. I think the batteries are OK, but the ESC was a complete meltdown! I only had it for a week. I was thinking something was wrong with it ever since I got it because it never worked as well as my other two Quark ESCs.

Dicky T had a similar thing happen to a Quark 125 but it wasnt during breaking, he listed some pics of the inside of the esc and it looked like some burnt up charcoal briquets

:lol: More like charcoal chicklets if you remember the chewing gum squares...I don't think they sell those anymore so you young'uns might not know what I'm talking about :smile:

I was on the Traxxas forum and some of the folks there are using the Traxxas Velineon brushless system in the E-Revo, but they are using them in pairs! Compared to the Neu, Feigao, and other motors we use on this site along with their high-powered speed controllers, the Velineons are cheap and easy to find. Here is a list of other advantages of this approach:

-Cheap Motors
-Cheap Speed Controllers
-Easy to find at hobby shops
-Great Traxxas support and warranty
-heat is spread over two motors so temps may be lower
-heat is spread over two speed controllers so temps may be lower
-Two ESCs means two heat sinks
-It can be run on 2s or 3s
-Higher kv motor (3500 rpm/v) means less voltage needed (lower temps)
-Velineon is super easy for both installation and programming...no soldering required...everything is in the Velineon combo box!!

Frankly, I can't see the down side. A pair of Velineons (two motors and two speed controllers is about $340. That is much less than a Neu and Quark 125. Mamba Monsters might change that equation since they are not too expensive, but who can find one?

OK, I just installed a pair of Traxxas Velineon brushless systems in the E-Revo that I recently saved from the fire. So far I'm VERY impressed. I have only run it at 2s so far (one 2s battery per ESC) and the speed and acceleration seem great for tight tracks. I did notice that I can't pop wheelys anymore :oh: I think going to a pair of 3s or reducing the size of the pinion gear would give it the torque to flip itself over from a dead stop. Right now I'm running 20 tooth pionion and stock 68 tooth spur. I'll test a pair of 3s (also saved from the fire) :diablo: tomorrow.

From everything I've read, the Twin Velineon setup is impressive. But as with most things, there are pros and cons.

You listed just about every pro known to man. LOL

I don't mean to be negative, but there are a few disadvantages to it also.

1. Extra Weight.

2. More Amp Draw - Lower Voltage setups are going to draw more amps to produce the same amount of wattage output at the motor(s). Which brings us to #3.

3. More heat at the motor(s). I've read where people who run this setup, say it runs hotter than what they think it should.

4. 1/8" motor shafts. Easier to acquire pinion gears, but the shafts are alot weaker than 5mm ones. I've seen more than one broken.

Give it a shot on the 20/68 gearing, but you are probably overgeared. Keep a close eye on temps to make sure you don't fry those motors. I would run it for a minute, bring it in and check. Then run it for another minute or two, bring it in and check.

Let us know hot it works out. :yes:
