Team Tekin Q&A

RC Disco is the distributor in the UK, I am not sure if they have a repair facility as yet though, contact them is best http://www.rcdisco.com/contact.php

Hi I have a strange problem with the RS and sensorless motors.
Using Vegas 208, running a sensorless tekin redline I have zero brakes and I mean zero
I have done all the usual, reset speedo, checked end points etc, all with no luck.

In a final desperate attempt I thought it could be something to do with the totaly sensorless running, so I plugged in a sensored motor into the sensor slot, with the sensorless motor still wired into the car, turned on the rs, waited for the confirmation beep and unplugged the sensor harness. I have not reved the car, which has the sensorless motor in, or moved the rotor in the sensored motor before unplugging the sensor cable.
Now the car has loads of brakes

Turn off the rs and on again, no brakes, tried the above again, brakes work

Is this a 208 issue? Does the rs need to see a sensor for the brakes to work sensorless after?

I tried these with the sensored motor in and the same thing happens. If I turn on the rs with the sensor cable unplugged I have no brakes

Can someone else running 208 with a couple of minutes to spare just unplug their sensor cable, turn the rs on and see if the brakes work?

Thanks Sam

Sam, could you email this direct to Tekin (support[at]teamtekin[dot]com) as I have never seen this.

[DCM]

Yes I get the same, tried it on a 13.5 on v208.

Thanks for trying it DCM, ive run sensorless motors on my old rs, i think i was on 1.98? no problems then

At least i know i dont have a duff speedo, i will send them an email.

Do you know if i can downgrade my rs to a lower firmware version, i have read this can bust the rs once upgraded to 208, but im not sure

Thanks for the help

[DCM]

if you email Tekins support, they even have a live 'help' chat facility now on their website, go through that. If you bought it in the UK, you may wish to phone RC Disco direct?

you have to reinstall v203 hotwire on your computer, but you can't downgrade with the hotwire having v208 on it. It is a pain, but there are big differences in the way the RS is controlled on each hotwire.

i bought it second hand when they first came out it well out of warrenty just wanna get it fixed without it costing a fortune.

[DCM]

then you need to contact Tekin direct, get a repair number, and send it in, it isn't expensive sending it over.

If you have no brakes in 208 you've either got your brake strength down or 0. Or you likely didn't get a proper radio/esc calibration.

When full brakes are applied ALL led's must be lit AND flashing!

[samd]

Randy, please read my above post re what is happening, if the rs with 208 is turned on without a sensor cable connected it has no brakes, with a sensor cable connected it has full brakes.
Brakes are set at 100% on esc and transmitter, full brake lights showing on the rs.
The only way I can get brakes to work with a sensorless motor is to turn the rs on with a sensored motor plugged into the sensor port then remove it after the rs has made it's confirmation beep.
Please try this on your own rs with 208, remove the sensor cable, turn it on, do you have brakes?

When I say no brakes I mean zero brakes not just weak brakes

[HarlowS]

Just out of interest have you tried re calibrating without the sensor lead in and the sensorless motor wired up ??? Just plucking at straws as i have never heard of this either.

[samd]

I recalibrated twice, I think once with the sensorless only and once with the sensored just in the sensor port, I will try again tonight to make sure. Are you running an rs/208? Care to try turning yours on with the sensor cable unplugged and see if your brakes work?

Thanks sam

[HarlowS]

will have a try later for you

Thanks pal

Hi

I'm looking for a system to power my 1/8 rallyX buggy, i race on large outdoor tracks and very rarely bash if at all, i'm looking to replace a couple of castle MMM 2200 systems.

A bit of background info; my gearing is 15 pinion and 48 spur, i essentially use 6S batteries, primarily because i have lots of matched 3S batteries, i do have a couple of 2S to make 4S but they just don't have the top end speed i need. i know it's bad practice but my current setup with 6S is too fast (top speed), so i limit the throttle travel on the transmitter, and also apply some 'punch control' in the MMM esc to control the power.

What i want to do is re-asses the situation and get a good setup going forwards, i'd like to use tekin RX8 and motors with appropriate batteries, my current thinking is; RX8 with 1900 motor and 5S batteries, i think when compared to my current setup this would lower the top speed slightly, so i limit the throttle less, and probably lower the power slightly so i don't need too much punch control equivalent, however i'm hoping this would still be a really powerful system, but more controllable. I'd rather have too much speed/power than not enough, i'd really appreciate some thoughts on this.

Questions;
1. Which would be the best racing motor for a 1/8 buggy, but still have have jaw dropping speed and power if desired.
2. Where can i get the tekin systems from in the uk, i know rcdisco are the importers but they don't have them in stock.
3. Why does the RX8 only have a 4 month warranty, the normal for items is 12 months, so if i built something i would want to warranty it for 12 months at least. i would only lower the warranty if i thought my product was incapable of lasting 12 months, this makes me think that tekin don't have a lot of faith in their product.

Many thanks
Lee

Hi Lee, Fusionhobbies may have some, and all Tekin products only have a 120 day warranty. If you check out the Team Setups page at Tekins website, they should show what motors they are using with different LiPo setups.

[lgbzone]

Thanks DCM for the reply, I'll check the websites out.

Standard warranty on most eletronics is 120 days. That being said we stand behind all of our products.

For running 6s the 1400 motor is the right motor for the application. Speed will likely only be limited to gearing and room.
