Hello!

I run a Team C TC10 using SKYRC TS120A esc, NOVAK Vulcan 4.5T motor and NOSRAM 6000mah 55C/110C lipo batteries. The esc is brand new and the other parts almost new.

The car works ok when is in the air, throttle and brakes seems ok, but in the track it accelerates up to a point and then almost stops! It runs very slow and the motor starts cogging!

Gear ratio and sensor cable are ok. Also using the latest software to esc.

Any help please?

Thank you.

If you've actually replaced the sensor cable and not just pronounced it Ok, Novak motors were known for bad internal sensor boards. I'd try a different motor as your next step.

Yes, i replace the sensor cable with a brand new one. Also try without the sensor cable and the problem was the same.

I will try a different motor.

how old is the ESC?
has it taken any hard hits/tumbles?

I used to run Sky RC in all my cars but found that over time, every single one that I ran in my off-road cars would run into problems with big air. I started using Kyosho gel tape to help absorb the impact... but nothing seemed to work for me. First I stopped running SkyRC in my 1/8 cars, then eventually had to quit the brand for my 1/10 off-road cars too. Never had any problems with my on-road cars since they aren't subjected to rough impacts and jumps at the off-road track.

I try a different motor and works ok with no problems. ESC is brand new.

Thank you for your replies!
