8 Pole Heli Motor in an E Revo?

[secondgear]

Outrunners work great in trucks.

I had an Axi 2826 in my E-Revo until it got slightly damp in the snow and shorted a winding. It was geared 20/40 with mod 1 gears and 5s2p a123. When I first installed it, I hadn't adjusted the slipper clutch from when it was brushed and I twisted the driveshaft into a pretzel.

I had also run this motor. Made a pile of power.

Depending on where it's run, it won't be a problem with anything getting into it. I had no problems when running on the street or on dirt, rocks, etc. Only when I ran in sand did the outrunner begin to get dirty. It would get dusty, but not get sand in it unless you really crashed it badly, then sometimes some sand would fall out when I shook it after righting it.

The thing I found that was the problem is ferrous dust. Small particles of iron attracted to the magnets. I would take my motor apart every so often and clean this out before it became a problem.
The amazing torque and smooth operation made this worthwhile.

Just my observations. Hope that helps.

It should be noted that the op was the reason I even thought to try an outrunner.

I've also been fascinated with outrunners and thought about using them on trucks, but the KV values are a bit low unless you go 6S or 8S. I've been using them on my airplanes and they work great. I wonder if any of Castle outrunners that they have on sale would work well in any of these trucks?

One of the reasons I will buy Castle's new 8S Car Controller, is for this reason.

8S on some of these outrunners will be insane.

I ordered one of the Castle Outrunners to try. It's the 34 38 1100kv version.

Yeah,
I cant wait to get a 8s controller either.

I'm liking your idea. I might have to pick one up. I bet that thing stays ice cold on 8S at the end of the run. I was thinking about the 1800kv version too, but it looks a bit smaller in size. Have you figured out their sizing yet? Is it a 34mm or 42.5mm in diameter.

Also do you guys know of any rpm limits on these motors? I havent tried spinning any of my outrunners over 15k rpm yet.

I'm thinking of getting one or 2 of the outrunners to toy with as well.

GREAT build

buuutttt.....
mines bigger

[Modding_out]

is that only 2wd?.....

Aaaah good point!

Yours might be bigger, but mines 4WD.

[shaunjohnson]

shaddup....2wd pwns


yeah ok so overall you win...least you got a good qual AXI motor.
i did my project because i couldent get enough power to the rear wheels with a center diff and wanted to go to 2wd for a bit.
also the COG is RIDICULOUS
flat out turns on the road with zombie maxx tires and no roll over...even without swaybars.

kinda bringing this topic back from the dead but I recently stuck a very cheap 1600Kv 6-pole outrunner in my Revo 3.3 conversion.


geared 15/36 with Elektri-Clutch. it pulls about 70A from a full-throttle start on 6s. Tops out at almost 40mph, but handles extremely well because it's lightweight (9lbs).

I used that motor cause it's roughly the same size as a standard 540, and will fit in the 36mm Tekno mount I had laying around. For larger outrunner experiments (or if I had the 42mm mount) I was looking at the Castle Vertigo motors that were $40, but the only ones left now are really low 220Kv. Kind of hard to gear those properly as you'd only get 30mph geared 30/36 (RCM sells a 30t 1.0M pinion!) on 12s lipo lol.

what motor is that?

i used the align 600xl and loved it in my buggy on 5cell, sadily i set the timeing wrong and it only lasted for about 6months

I use this one. It's almost exactly the same size as a 540 size motor, and works perfectly with the Tekno 36mm motor mount. I just had to drill a hole near the front for the wires to exit...if I need to take it out of the mount again, I will drill more holes for ventilation. It's not a very powerful or extreme setup (running on a 6s 2650mah 20C lipo just fine) but it works well, and makes the 30krpm recommended lower limit.

What timing were you using? I heard outrunners like high timing regardless of what they're in, didn't know they reacted so poorly to bad settings.

got a video up of my outrunner'd 3.3 :D finally got my Mamba Max Pros back. I still have to lower the shift point, it's at the very upper limit of RPM so when the battery is about 50% discharged it can't reach 2nd anymore...
