I just got a Mamba Max 6900, I plug in the battery and turn it on and it beeps. The light stays red tho, and if I give it throttle the green light blinks and nothin happens. What does that mean? I bought this used, I know it works because I ran a battery through it once. Please help me out. Thanks

That's called programming it.

When you turn on the transmitter then turn on the esc and it beeps push the throttle for 3-4 seconds(a green light should come on). Then you'll her it beeps after a moment.

Then put on the brake, you'll see it turn green. Keep it on the brake position for 3-4 seconds. It should beep again.

Then put it in neatral all together(let off the trigger all together) you'll hear beeps. Wait about 5 seconds and your ready to go.

Make sure everything is pluged correct and your cells are peaked.

Hey man, thanks

Might be off topic but I run Castle stuff in my mini latemodel with a DX3R and I MUST turn on my radio first or the esc will not work. I know your supose to turn your radio on first anyway but with 2.4 ghz and the built in failsafe it really isn't a big deal.
