Hello all, i am new to the forums... I am back in R/C after a 12 year break. Technology sure has changed. Anyways, i just picked up a Spektrum DX3R and one thing confuses me, On the main screen the Brake Trim way at the bottom, what does that Adjust? Is it functional on a nitro car? Reason i'm confused is because i'm use to adjusting brake trim using the throttle trim controll.
