huh? I thought you wanted to disable the delay for reverse, the RX8 does that... in any ESC that is not recommended as you can blow the guts out of your drive train with the shock of nailing full reverse with full forward momentum still in play. But it will do what you are asking.

Another thing, re-calibrate your ESC, I have had them from time to time be very hard to find reverse in and the reason is the ESC will not allow revers until you were in neutral for a full second. If the ESC has a hard time finding neutral because it needs to be calibrated or because you keep trying to fish for reverse you will just site there and make the lights blink.

The secret to reverse with Tekin products is that your ESC needs to sit idle in neutral for a full second before you can use it. That not only means that proper calibration is big deal, but that means no throttle input for that full second from the radio either.
