my get 2 RX8/tekin 1900 motor in 1/8 ebuggy was cogging/turning off all throughout my runs! I replaced sensor wire, that wasn't it
I'm thinking its either sensor board on motor OR esc connection between the boards
I had throttle then none then back on every couple seconds
sometimes It would lose steering also and transponder was not being picked up every lap
ALSO, If you pull gas trigger nothing happens, IF you push it and pull gas while rolling motor gets power

any help?
thanks

Did you try running without the sensor harness at all?

Have you opened up the motor? If it’s equally bad in dual mode and sensorless mode, it could be a short in the motor. Let us know if any coils are burnt looking.

So im getting back into electric 1/8. Im finding it hard to source 12awg wire where i am. But can easily source 13awg. Will that be fine to run in 1/8 offroad on the gen2 esc, or will i need to source the 12awg wire? Cheers.

Personally, I would be okay running quality 13 gauge in buggy. Sketchy or cheap 13 gauge might not cut it. 13 gauge of any quality in Truggy would be pushing it in my mind.

I can get TQ wire. Not sure of the quality as i always run Tekin wire normally.

You should be good to go with TQ 13 gauge.

You have the correct sequence of lights.

Check all of your solder joints, battery plugs, condition of wire at the battery plug is a usual culprit. Sounds like your esc is rebooting due to power outage (bad connection)
Ask me how I know LOL :rolleyes:

Since tekin won't answer a simple question on their facebook page I hoping someone could answer my question here. Will a RX8 genIII run a 2.5 turn 540 Drag motor?

Hey Mike, we do not monitor all our social media pages daily. If you'd like to get an expedient answer, feel free to email me at [email protected]

While the Rx8 can easily run that motor, I would talk you into the RS Pro BE for a drag racing application. It will also handle the 2.5T motor and it's rated for more amps per phase than the Rx8.

Hello i am new to the site. I have an RX8 with a 1900kv motor and 16/46 gears. I feel like it is sluggish and nit very fast. I also have a stock slash 4x4 with the brushless motor and it smokes my 1/8 buggy. Just desperate for some help on getting this running the way i think it should. Thanks for any help you can give me.
