Default CK hobbies 540 4 pole motor

Has anyone tried the CKhobbies.com 540 4 pole 4000kv motor?
http://api.viglink.com/api/click?for...3581%23msg3581
I have one coming so I'll leave feedback after I run it. It "should" be a great 4wd SCT motor, we'll see after I put it through it's paces in my SC10 4x4. The rotor is an 18mm 4 pole, should be lots of torque

As noted in the other thread that rotor shown is NOT from that motor referenced.. not only is the shaft different there is a bump out on it.

More info on the motor is welcome though..

Yeah, I noticed that shaft right after I posted the pic. I'll pull the rotor out when I get it and measure it to see if it is indeed 18mm.

The above picture is from a 3668, 5mm shaft with a 18x39 rotor that I am currently working with.

The specs as posted for the motor is correct but I had shown the wrong rotor.

36x50
4000kv
4-pole rotor
12 slot stator
Y wound
3.17mm shaft
1300 max watts

Here is the correct one pulled from my Sparrowhawk XT







Sorry for any confusion.

I have this motor but have not tried it yet. I can tell you that the magnets are as strong as the castle 1410. Very strong. Very notchy. Hopefully I'll get a chance to run this beast in the next week or so. I'll start out with 16/54 gearing in my slash 4x4 and go from there.

Yes it is.

The outside appearance is not spectacular by any means (will change) but beauty is only skin deep

Matt,
I tested this motor today. Before my heats at Mike's. I tried in my jammin' with mmp esc and 14/46 gearing, 5000mah 2s 40c GenAce Lipo. Have to say, i was completely shocked by how much torque and speed this thing had. With that gearing and set up, I was a little too much for the track. I backed throttle to 95% and was able to get around the track and clear big double with ease with just a tap on the throttle. Front line and straight away speed was awesome, On/off throttle in and out of corners was amazing. Pulled off the track after 8 min run and motor temped at 140.
I am pretty confident you will not be disappointed with this motor. Especially the way you drive you will be that much tougher to beat
I also tested it in my AE SC10 4X4 ( If you remember, I am the purple and green one that ran with you last saturday). Ran it with the 48P 93t spur with 17t pinion. Again, very smooth, off /on punch power. I can wait to get a couple more heats in with it. I will try 16t/ 18t configurations during the week and also 32P/63t spur with 12, 14t pinions.
Again, great motor.

Guys give this motor a try, I am sure you will love it.

Sweet, sounds like a good substitute to the castle 1410 you can only get bundled with a crap esc. I'll have mine ready for this next weekend, now I REALLY can't wait

Wow ! I ordered mine on Saturday (morning) and the wife just let me know it arrived. Too bad I'm working out of town. Good chance it will find its way into a losi scte or a hyper this Friday. Looking for something comparable to my 3800, which is plenty fast and runs cool.
