ddesros2 thanks for the help!
I am running Expert/Mod class.
For Tamiya cup you are allowed to run any Tamiya 540 motor, currently I am using the Tamiya 11T modified for that class. For club level I also run the car in open super stock and run a Tamiya Super Stock TZ motor. At SADA level I am running the Orion Reheinhard edition.
The main reason I make my comment about peoples knowledge here in South Africa, is because everybody has their say and about 5-10% of the comments said are only right. So with no offence, I rather come here and get advice from people that know exactly what they are talking about and more importantly will get feedback from.
At the end of the day, you come to these forums, so I have no doubt in my mind that whatever you say will be spot on most of the time.
