How many channels do i need?
 

Hi,i just finished my first berg roller and was wondering what would be the best set up. I have a (punk dig and a tekin speed control with castle bec) and i have a( rc4wd dual motor speed control with turbo bec). I was wondering what would be the best set-up for front/rear dig and how many channel radio i would need. Thanks"thumbsup"

You can run your Punk/Tekin set-up with a 3 channel radio. You'll need a 3 position 3rd channel to have both front and rear dig. I'm not familiar with the other ESC you mentioned.
