calling them is soooo much faster, you get an answer and a new rotor shipped now instaid of 3-4 days from now...

I'm in Australia so calling them is a pain. I'll do it if I have to but I would rather have my sleep.

It looks like I am going to have to call them. No response by e-mail so far.

contact support@teamtekin.com . You should get an answer within 48 hours.

So far none of the new rotors have failed....

thats good to hear. I am starting to push my mugen way more than i used to relying on slipperential to protect the drivetrain

Hi Guys,

Couple of questions:

Has anyone smoked their RX8 ESC yet???
Would they be considered more reliable, or should I say less prone to failure than the MMM?
Is everyone using motor braking successfully without blowing CAPS?

cheers

Hey guys, I finally got an RX8 System so I thought I'd post up a few comments, answering a few of my own questions in this thread...

• I bought my RX8/2050 combo from A Main last week. As soon as it arrived I opened the motor to see if it was a new style or old style rotor, it was the new one.

• Fit in my Losi was great but the Servo lead was too short, an extension is needed if you are mounting it where the ESC is designed to go on a Losi 2.0 conversion.

• I raced it hard yesterday. Ran wonderful. Very smooth, considerably smoother than the Losi I had in my buggy. We run 12 minute A mains at my track, took home the win! (2nd place was also electric...3rd was nitro...)

• The 2050 buggy motor ran great but geared the same had a little less kick than the Losi 2100 I replaced. I'm not dissatisfied at all, just making an observation.

• I bought the Hotwire but aside from Timing changes, I'm not sure one actually needs it. Nice to have but the LEDs on the ESC are like nothing I've seen, very slick.

Glad it worked out. The Hotwire is also used for software upgrades when they come out...

Where is your timing set now?

Thanks, I forgot about the Software/Firmware updates, that is the thing which tipped me over to getting hotwire. I know you guys are working magic daily so when that magic goes release grade, I want it on my ESC...

My timing is at 10 right now. Not really sure what the scale of the adjustment is but I wanted to leave it "factory" and start with a safe, reliable setting. Do you think I should move it up?

Dave, you can try more. 10 is a great place to start for sure. Go up to 20 and see what you think. I don't go much over 30 with most motors.

Just another reason to have the Hotwire. You WILL notice the difference in timing.

I'm trying my buggy 2050 on 35 since i'm undergeared and can't move up to a higher pinion due to my motor mount holes. 62 spr/16t pinion on my F8T.

ive seen everything from smoked esc's to bad rotors....but they are working on the problems

I didn't "smoke" mine, but it did die on me...:cry:

Had a race last weekend in Belgium. After a few batteries off training, there was a 4 times 10 minutes Heat race. After the 4 race, last round, 20 secs....it happend....

My new style Rotor was broken. One off the magnets broke from the rotor:surprised:

Appart from my problem I was second in Race:lol:

thats not good. looks like i will go back to Neu just to be safe

Ouch!

My new style rotor is still alive, raced it again this past weekend. One practice, two 5 min Quals and one 12 min main, held up just fine. Finished 3rd this week...

Ouch! Well Castle had their problems looks like Tekin is getting their fair share aswell. Still two great systems.

Yeah turns out that I never actually sent you an e-mail which is why I never received a response. My client decided not to send it and not to tell me, along with a whole bunch of other e-mails I tried to send. Anyway I called and a new rotor should be here any day now.

you can put a photograph of the new magnet?

Hey no worries, things happen. Glad it got sorted.

Just an FYI, at the bash on Sunday there was a rx8 in a buggy that went up in flames, I was a marshal and got it off the track. Battery wires unsoldered from the deans and I beleive the posts as well. There was another rx8 that had issues but nothing so spectacular. And to keep things fair here I myself smoked a Mamba Monster. So both ESCs still have there share of failures

I wonder if the battery leads shorted causing the fire?

My RX8 held up to two consecutive days of abuse just fine. (raced Sat & at the Bash Sun...)

Well where the battery was soldered to he deans still had the shrink on it so that pointwasnt the problem, but that's not saying one didn't come off the esc and short out against something. The power wires where unsoldered from the esc and the deans, then on the pack side they where also unsoldered from the deans

if the power wires came off the speedo that is not a good sign. Chances are that there was a cold solder joing and wires touched...no good for anyone.

New rotor failed...
 

I was racing yesterday, got new rotor from tekin some time ago, no problem so far. It was long main with nitros and I was like "well we will see if it will hold up" I was first after changing batteries, so I slowed down not to rush things.
Well long story short, car started to go slow and I didn't reallized that it is rotor out from magnet again. I guessed it's because I put wrong batery in (it was long day) so I went slow about 1 40 sec lap. It was 2mins to end of main so I hoped to finish really slow.
My bad, magnet was out from shaft, therefore temperature went to skies and I guess rotor is demagnetized a bit now.
Still finished second, but quite a dissapointment.

how do you know if your motor has the new rotor or the old one...i bought a 2050kv t8 from amain a month ago and curious to see which one i got

Thats the new rotor

easily, old rotor has 100% failure rate among guys I am racing with, me included, so this is rotor I personaly replaced old one with.. and it's looking slightly different too.

The old rotor isn't 100% failure rate. I've still got one in my 1900 and have since day one.

We've seen only a handful(less than 5 last I counted) of the new style. We're investigating any failures as always...

Contact support@teamtekin.com so we can get you back up to speed.

my first rotor went on the first pack. was replaced with the same style rotor and is still working fine. I did have a problem with the bec since then though and had to send back in the esc.

well we got 5tekins, all of them were dead before second race day. Just 100% among us. Some ppl might get lucky and old rotor is still fine, some ppl are just unlucky (like me) and have new style broken already.

mail sent yesterday. Hoping for fast solution.

so far so good for me, im still useing the first rotor too

My first rotor (the original one) failed within 4-5 laps of first running, which was a little disappointing. However, I emailed Tekin, and they sent out a new rotor, without a fuss, and I received it the day before the next race meeting. It then ran the whole meeting without issue, and I'm rather liking this RX8/T8 lark. Just wish that the Hotwire was compatible with Vista 64.

Yep my new rotor's just gone as well, 2nd time out total of about 27mins running, not even racing yet, just taking it (relatively) gently, have e-mailed Tekin, hopefully they are as good as everyone says.

email takes 48hrs+ call them tomarow and you should have a new rotor before next weekend:yes:


I must say, that the RX8 has held up awsome against my abuse:oops: only had to send it in twice:whistle:

I wouldn't call it reliable ;) I wanted to buy tekin again, but from here, in europe it would be a disaster, 1 race, 1 month or more waiting nad 20-30$ shipping. I chose Neu and MMM and no problems at all. But it is a pity, rx8 seemed to be mamba killer, but even esc gets quite many failures, mostly because of electronics getting loose during crashes (sensor plate and so on).

Well tekin was my first "real" racing equipment and I can thank them for great time I had, but I just don't trust the motor anymore and with that in your head "it can die anytime now" you don't have proper mind setting for racing. So I have already neu for replacement and after winter I will buy any new neu that will come to market...

Looks like one dead ESC here. Simply wont "command" the motor, no chimes or turning the axle. Leds work fine as well as HotWire. Too bad they wont move my car :lol:

Going to see when the tekin support replys to my email. Wont be calling to their support from Finland :whistle:

Please email me here. I might be able to help: Rpike@teamtekin.com

I"m attending the IIC onroad race here in Las Vegas. I only have internet late at night so bear with me.

I have to report just another dead R8 truggy ESC - Motor 1700 set .... It only worked 1 minute on our local track before it stopped to turn the motor. I plugged in my MMM 2200 set and drove about 2 hours without a problem afterwards.

It is very disapointing to receive a set (with the hotwire link) in beta stage. (My CD included with the hotwire link was EMPTY !). I had to download the Hotwire program from the Tekin homepage ! Everytime I start the program an error message pops up that this version (the newest) probably won´t work with the esc and some values were out of range ... very strange !

Now I have a brand new set which doesn´t work and I have to pay a high amount to send it back to the USA . (I am from germany)

What can I do ?

Can this error be fixed with a firmware update ?
