I have no doubt Tekin will get it sorted,in the meantime i have laid out a lot of money,for a truggy that i cannot race because of a quality issue that should have been sorted long before now.I know Tekin are sending out replacements foc,but when the replacements are failling in under the time it would take to do a qualifying run,thats a waste of a complete race day.Maybe Tekin should see how the Neu rotors are constructed,can't remember ever hearing one of them failling.

well last time I was happy... sort of "be happy while it last"

my rotor again separated.. that is third rotor of new design failed..

and now tell me, what are the chances of actually getting money back? anybody did try it? I quite like the ESC, but motor is just unnaceptable. Any tips / thoughs / solutions?

i agree - clearly not the best outcome to have - but are you guys running direct drive setups? =)

well slipperential... I invested into it not because of driving and handling I wasn't that skilled to even tell the difference before.. I invested to save my motors/rotors... without slipperential rotor will last even less I guess...

Yep,direct drive,but with mechanical brakes,i am going to give the clutch system a go,but if the Tekin rotor fails again !!!!!!

I'm on direct drive. I have a slipperential coming though.

In fairness though, I've run direct drive for the last 8 months in various cars, and only the Tekin rotors have ever failed.

I ran a Losi motor today, same set-up, same kV, etc as the Tekin. Rotor didn't fail...

yeah, im sorta not really going on a comparison to other motors (we all know it shouldn't be happening) - just trying to figure out how and why these particular ones might be seperating.... i have my fingers crossed mine wont let go...

I'd like some input from Tekin here with their thoughts on the situation (also why they think it might be letting go) and what they are doing about it... It's a real shame tho, cause i really like my tekin setup =)

I only ran the Losi motor as Tekin failed to get the replacement rotors to me in time.

It appears almost all the V2 failures are not from the US. They seem almost all European. I can't help but think more testing is needed in environments other than US tracks. European tracks are far more flowing and bumpy, they aren't overloaded with jumps and straights, but more sweeping corners and 'obstacles' such as rumble strips, bomb holes and banked corners.

I'm a little disappointed with how long it's taken Tekin to get my new rotors here. Three weeks tomorrow since they said they'd sent them! I know I'm not in the US, but for a company trying to 'regain my trust', choosing very slow shipping, so I had to buy a new motor to run last race meeting, is not a great idea.

Sunday is the last race meeting of this season before I run 1/10 off road indoors, and I'd like to give my Tekin a run to see if I can actually finish a final with it, particularly because I have my new slipperential.

The same here ... I think I will receive my ESC back in early 2010 ...

From what i've seen following brushlessboy16's thread titled the Brushlessboy16 curse, Tekin has been able to get him his rx8 fixed and back to him in a week or 2 both times. Granted, he does live in the USA, so that timeframe definitely wouldn't apply to the UK and germany. But repair time in tekin's factory should be the same. If any of my stuff had to be sent overseas, I know I'd be calling about it just about every day

Got new rotors in a weeks
RX8 (the messed up one i got from tower) turnaround time about 3 weeks with registered airmail to Tekin and USPS Airmail back so quite good.

Tekin service has been so far top notch, if only the rotors were not .......

I'd like to know what setup you're running and having rotor issues. I'd like gearing, car, battery used,etc.

Well for me its a Tekno rc v3 x2-crt conversion running standard spur,12 tooth pinion,tekin Rx8/T8 2000kv truggy motor,hyperion 5s/6500mah G3 lipo,firstly, used direct drive,v2 rotor broke,2nd time used mechanical brakes, with esc drag brakes and normal brakes turned off,replacement v2 rotor broke even quicker,third time i am going to try the tekno clutch,with mechanical brakes,on a 13 tooth clutchbell,hopefully the rotor will last longer then 4 minutes,but will let you all know.

That is a lot of power! 2000 on 5s? I'd rather see a setup around 5s 1700 or 1550. I'm sure your setup works. Do you turn down the power?

Losi 1.0, 2.0, Xray XT8, MBX5T

All are 1700kv motors on 5S running either Zippy 30C/40C 5000mah, Hyperion G3 35C/65C 3300Mah and 4200mah or even A123 6S2P

All temps are normal. Nothing showing extra stress on the motor.

All cars are under 10lbs RTR

80% of the cars use RCM slipperential.

All geared 38-43mph

Different cars, different driving styles, same motor issues.

All I did was change T8 with Neu 1415 and I am sure it will last forever. As I used to run Neu 1512 2050kv on 5S in my mugen and no issues. The Neu 1512 used to be in ma heavy bashing maxx and went throught lot of stress with flying colors (including hammering stuck pinion) and still works great.

Rest of the guys will follow as I dont see a single reason how can our setup cause loose rotor as most failures differ. Sometimes just magnets separate, sometimes just the front spacer along with couple pieces of the rotor.

With the rotor being made from so many pieces the glue is not strong enough.

Hi got the current limiter turned down to about 60%,did originally order a truggy 1550 motor, but got sent this in error,but it took so long to turn up,i did'nt worry about it.

If I don't ask to look at setups we can't understand what everyone is running. If say a guy run your setup is breaking rotors frequently while others are not than we need to change our testing to your setup to reproduce the failures... I don't think your setup is the issue...

But I can learn from your failures just the same, so I ask.

Well I have to say, that I am running 2000kv motor on 5s as well, both in truggy and a buggy, with slipperential. 12tooth pinion. Did changed it to 14tooth for one big track.
Could be a problem, that I should use 1700kv motor.
So now I have 2100kv castle neu in it and I will see if it breaks as well.

btw, I is teamtekin on vacation or something ? not getting anything back from support for my last rotor issue ...

No, nobody is on vacation. We were closed for the holiday on monday.

I'm surprised to see guys running that "hot" of a setup. I think a 2000 on 4s is plenty on all of the tracks I've been to.

I'm running:
1700kV Tekin T8 on a Tekin RX8.
Current limit: 60%
Lipos: Hyperion 5S 5500mAh VX (35/65C)
Gearing: 42/16
Car: Xray XB808
Overall Weight: 3.74kg

When it does work, all temperatures are well within all the limits, ESC is cool (about 4th LED, only one LED on), battery is cool, motor is hold-able.

Thanks guys, really. It's interseting to see the combos being run.

I bit of good news.

Mine runs great with the new rotor. I have been racing it for the past 2 1/2 - 3 months with no hiccups. Absolutely recommend Tekin and Ty. Got my rotors with-in days, so I could race the weekend. The best system by far.

MBX6T
2000 KV combo
Slipperential (a must in my opinion)
46:16
Avid Bearings
Various 4S set-ups (currently loving the Hyperion G3s - wish I had more)
No drag brake
Very, very little brake dialed in (still will stop on a dime). ABS set on my TX.
Low current limiter setting (currently LED #4)
Throttle Profile #2
Higher Nuetral width setting (currently LED 7)
8 degrees timing (might drop it to 0 to squeak out another minute or so)
100% expo on my TX.

I'm not sure if I have the old style rotor or the newer fixed type but I just went out to test my freshly installed bearings in my tekin 4030 and my magnets started spinning on the rotor:cry:
And I thought I'd get to race by buggy tomorrow, guess I'd be running my trug:neutral:.
Someone mind PMing the address I need to send this thing to?

You can fix it. Loctite 409, 2 part epoxy- hell I have fixed a feigao motor with strait Medium CA

you can do do it.



As for me, I have tried the rx8 on

CC 2200
CC 2650
Aveox of unknown denomination

When it last went up it want all spiteful and took out my castle motor.

the day after it detonated my tekin t8 1900 buggy motor came in.... which is currently running on a Mamba max while my rx8 is getting re placed.


Irony:party:

the tekin rx8 doesn't include wires for the battery? I got mine without them, only motor wires. And couldn't find anywhere in the manual a instruction on where should i attach the sensor cable support.

CHeck there website. and I got enough wire for everything...

I got some new rotors off my uncle (who was sent buggy rotors, not truggy rotors), so was able to race this weekend. I had my new slipperential to try, which went together perfectly.

I ran an XB808, 46T spur, 17T pinion, 1700kV T8 on an RX8. 5S 5500mAh 35C Hyperion. Slipper was fairly loose as the track was dusty and had little grip.

I qualified 5th overall, only my pinion came off in round 3, meaning the run was useless. I decided not to change my rotor for the final, just to see if it would last. Even with a run-through-the-pit-lane stop-go penalty (as I didn't have to stop for a battery change), I finished 4th, only about 7 seconds off 3rd after 20 minutes.

With a combination of the new Tekin rotor, and (probably more importantly) the slipperential, I've finished my first ever final with the Tekin (all the rest have been DNFs). This is the best result I've had all season with the Electric, since my second meeting with a battery change, a Medusa motor, and an MMM.

Well done. Kudos to Mike for making such a revolutionary product for Ebuggies and Etruggies...

Congrats chap! :party:

How did the Slipperential make the difference do you think?

It makes the car far easier to drive out of corners, particularly on loose/low grip tracks (like my local track). It also seems to help the car over ruts and bumps, calms the low end down, and makes it generally more forgiving. It also seems to add rear-end grip.

Sounds good, I have very bad memories of the slipper in my old savage :whip:

Do you think it will aid durability with the ESC/Motor to lift some strain off them long term?

Yep well done Marv,you stuck with it and now,hopefully its sorted,gonna fone Tekin tomorrow about them sending the wrong rotors(another weekend racing missed:grrrrrr:)getting a bit annoyed and impatient now.

I think it will actually, it certainly made my Tekin last all day!

Were the temps lower and/ or other indications there, that the Slipperential is helping?

The motor temps were lower, though they were hardly 'hot' in the first place. It could have also had something to do with the 46/17 gearing on there, which was better geared than with a 42/15.

Today I received my ESC back .... they repaired my brand new RX8 instead of sending me a new one and opened the case of the ESC so unprofessionally that anybody could realize that it was repaired ....
Fine ... so I cannot sell this ESC as new on ebay . Maybe I will try it out myself so that I can damage my motor (1700 truggy style) also. Then I have to wait another month for the replacement.

Here are some pictures of my "new" ESC - (I ran it for only some seconds - before it was "repaired")

We will often repair the speedo if that's all it requires. However the case shouldn't have been cracked like that. It might have been missed which is unfortunate.

Please email me your shipping address and I'll see about getting you a new case set: Rpike@teamtekin.com

I sent you an email already ... but it is very disappointing ...
