Emaxx Quark 33amp/Cyclon Outrunner setup
 

I got a little bored waiting on parts to arrive for my E Revo conversion. So I decided to dig through my goodies. (You know, those boxes of parts and extra goodies.)

What I found was a Cyclon Car 2000kv Outrunner motor. (Does this motor look familiar Jhautz? LOL) I also found a Quark 33amp Procar ESC, and a fan with mount from a Novak setup. I also found a 18tooth pinion for the motor and a 74 tooth Robinson slipper setup.

I decided to put together a setup that wasn't built for top speed. It's a setup that isn't the top of the ladder as far as power goes. But that's not the point with this setup.

One of the biggest benefits of brushless is that it's more efficient than using brushed motors. I wanted to put together something that would perform alot better than stock, but not so radical that I couldn't see the extra runtime that Brushless will give.

I was also curious about this Quark 33amp Procar. An Emaxx is ALOT of truck for it to be pushing around. This is also why I chose this gearing. "Let it wind up with the lower gearing" I thought.:yes:

On board, I have 8000mah of 4S2P Lipo (cheap ones, I'm not that impressed with).

I now have a MRC Superbrain 989 charger. It's a GREAT charger/discharger. It will measure how many mah I put back in during the charging process.

I took it out today between showers and it performs pretty good. The Cyclon is alot more powerful and has more torque than the stock twin titans these come with. Tops out about 35mph or so. But it will take off in 2nd gear without any sign of cogging, just like it does in 1st. It will carry the front end pretty good considering.

When the weather breaks, I intend to do runtime tests. Minutes of runtime versus mah of power used. This should be interesting.

I've really got to hand it to Quark. I didn't think the little ESC would do it. The heat sink does get warm if I stab it good, and feel of it right away, but the fan cools it off quickly too. I ran it for about 45 minutes today and it didn't thermal.:yipi:

oops here's the pic

Cool. If you gear it down and put spools init. May do pretty good at crawling to. :)

Oh, those poor FETs! :smile:

LOL Brian.

If I hit the thermal cutoff on the ESC, I'll drop some more gearing.

Yep... I looks like it used to run a 1/8 buggy in its past. :whistle:

I gotta say, it was a decent little motor for its size and weight. Just not the kick in the pants that I wanted.

I am very surprised that the Q33 handled that. Seems like a really big load for that esc. WHere were you running it? Pavement? Grass? I could possible see it surviving if you drove it easy and stick to the pavement. I have a Quark 33 around here somewhere. Maybe I'll toss it in the revo and see if it can take the 1521 and 5s :tongue:. Lord knows the 125B cant do it without overheating. Maybe I have just been using the wrong controller all this time.

LOL Jhautz, you're too funny man. You have some AWESOME setups.

I didn't think the Quark 33 would handle it either, but I like to experiment. It doesn't get hot enough to burn my finger though. LOL

I was running it in the grass, on gravel, cutting donuts on the wet concrete driveway, and played around climbing some 6 foot tall dirt piles with it.

It should be interesting to play with. If the 33amp esc starts giving me trouble, I'll probably put my Quark 80 back in it.

I just had to see though. I didn't think this motor would draw that many amps with the gearing used.

This motor was in a Rustler for awhile on 4S with the Quark 80. I geared it pretty high, and it was awesome on 4S Lipo. It stripped the stock tranny gears pretty quick. After the upgrades, it would get up on the wheelie bar at 40mph.

Do you have an eagle tree? Id really like to see what kind of power that littel thing is handeling.

No I don't, at least not yet. I have been looking at them and I need one for collecting data.

I noticed Novak is coming out with their own version of the Eagletree. The Sentry Data Logger. I wonder how good it is?

On the Cyclon website specs for the Car 2000 are:

"Power with 16 cells : 600 W continous , 900 W peak (30 seconds)
Efficiency : 89% at 16v - 31amps, Timing 4 degrees
Current: 35 A continous, 60 A peak (30 seconds)
Kv = 2093 Io = 1.7A (6v)
Dimensions : Diameter 36 mm, Length, 53mm (without shaft), weight 160g"

I figure I'm right at the rating for the ESC, but I'm slipping by with the added cooling of the fan.

I took a closer look at the winding and the magnets in this motor. It is a 12 pole stator wound like a 6 pole! Inside the endbell the magnets are extra wide. It is being operated as a 6 pole. Interesting. I would love to play with different windings and be able to record the rpm's, amp draw, etc. with 12 pole outrunners. (whisper whisper--------Direct drive E Revo):yes:

wow, i have a gs storm that could use an outrunner and my 33amp. i'll watch how you setup goes and maybe try a 5cell setup.

The winding scheme of the motor is ABCABC with 8 magnetic poles I believe. It gives a 4:1 "geardown" and 4 times the commutation cycles per revolution. I am not surprised that they system works for you, and I bet your runtime will be obnoxiously long. When tooling along I find the amp draw is very low for outrunners, Once they get running the inertia seems to keep the amp spikes down or something.

Hey sike, try adding a novak power cap to the input leads of the quark. Use the cap that they sell for the HV system. I have a few installed on MM and they really cut down the heat, especially on long runs. Anything to help the little qyuark survive. The cap will help with current spikes. You sound like you have plenty of battery capacity, voltage drop also leads to heat build-up. Sounds like a cool setup, is it 2wd or 4wd?

Hmmm, I may do the capacitor mod. I'm sure that would help.

It is a 4wd truck. :yes:

Yeah, the cap mod really keeps the temps down. It is not as good as griffinru's esc mods but it does help. I do not need a fan anymore, and I am running a body that does not have any holes in it. I plan to mod all of my MM escs theis way, and check that the heatsinks are glued properly too. I have a small aveox motor that I want to try in my tamiya m03, and will most likely use my quark 33 on that too!
