Tekin Redline brushless motor

[Mister-T]

Hello,
I received my Tekin motor.

Overall aspect and packaging is great, it made the motor looks like high end product :P, packaging say
Designed in USA made in China.
Come with everything, including inox (!) mount screw, spring connector (the good one, not the banana) 11 ga wire and a bunch of stickers :), and the motor

by the feeling it's slotless design maybe with a iron ring (can still feel a very very ligh resistance in the rotor at some position).

I used it yesterday, feel strong and smooth power band with my mamba max, run great even with bad battery. Very silent as well.
Summary, for 75 $ we have here a good alternative to Castle creation motor, with a larger choice of KV and lot of stuff inside the box.

PS: I still want Mamba max stickers :|

Mount in the T4

Good to know. Thanks for posting this. I was considering one of these motors but hadn't seen anyone try them yet. DOes the package give any info on Max RPM or max voltagethatcan be used with each of the motors? SUrely the R1Pro/Redline 9000kv can be rated at 3s.

Nothing on packaging sorry

Just a small add,

I have tried to change timing in my MM, from 5° (low setting) to to a custom value 8°, I can't say if does change a lot run time or T° because I just tested it in the street, but you can really feel the difference in term of punch, I hope to be able to do more test next week if weather is better

Anyone had any dramas with these?

[Mister-T]

I doubt you won't have much feedback on it here, so far I just found soldering post a little too small to solder wire on it.
There is not much info about this motor mostly because it's not roar legal, and tekin stuff are mostly aim toward Racers, Many racers still relie on the "seen on the track" instead of adds and hype of RC forum to buy there next RC stuff. At least It seem to work for top level driver here in France

[DRIFT_BUGGY]

Yeah just wondering as it has lower KV than what the Mambas have so they could come in handy

Hello,

I did a small movie to show how Tekin motor work with a Mamba max, the car is messy because I did run on the my local race track before.
I will try do a movie there too.

Youtube kill quality, I have a decent webhosting, movie is about 10 MB in Xvid.

I think better acceleration is achievable easily with Lipo and more agressive ESC setup, but it's already more than enought to race with the big dogs (1/8).
As you can see there is hardly any cogging,
and you can ear the start-up routine of MM taking over when motor slow down too much when hitting the curb,
I keep the small throttle value at this moment.

(from an original post I did on Rctech)

I did dismount my T4 gearbox for some cleaning (to much grinding in that differential :P).
I did that for my Tekin motor as well.

I must admit, I'm impressed by the overall qualtiy of the internal build. Except of two copper strand that were misplaced and a slight bending on rotor side, most other sensorless motor on the market are way cheaper in term of construction.

How is your motor doing? I'm thinking of sensorless 2.5t, but not sure if it is better than hacker or gm...

[Mister-T]

Still working flawless, I run around 70° celsius with 23/87 gearing.
Hacker E40 are made in china stuff.
I can't say about hacker or GM, but on thing is sure. There are not based on the same design. If you plan to run with a sensorless ESC (VXL/ Mamba max/ Losi entry level ESC / Tekin R1) , A tekin motor is ano brainer. They worth every bang for buck.

I know that TC/On road is very hard on sensorless setup because off large gearing they do use. But on off-road the drive feeling of this motor is good.

[Kajman]

it will be for tc :) My e40 lost magnets after 3 months, f...ck :( GM makes very, very good stuff, especially their new line, but tekin has always been well known for quality. And their motors don't look like anything I knew.
It will work on GM Genius 95 esc, strong beast.

[Mister-T]

I have read that new GM range use delta wind motor, Tekin are delta wound motor as well.
Bearing on Tekin motor are really large, and the rotor seem to be made to pull a monster truck (compared to a common SP/ Novak rotor)
Please let use know how the combo work.

[Kajman]

problem is,that nowhere noone says anything about efficiency, current draind and operating voltage, what may be a problem :)
