need help here. i will start off by stating the stock tx,rx work fine with the mamba 25 in the rc18t.
now i brought used a spektrum dx3 and a sr3000 rx. the problem is when i hook up spektrum stuff. with mamba 25 wire going to throttle,all that happens is the light on mamba blink.. i have steering..... but no throttle at all forward/rev..
now i try taking steering servo wire and moving to throttle on rx and the mamba wire to steering plug on rx. and have throttle by using wheel and steering by using trigger. i have flip the mamba and steering wires to rx and on good either..
any ideas.

You need to recalibrate the ESC for your new TX


3.1 Calibrating the Mamba 25 to YOUR transmitter:
IMPORTANT NOTE: Calibration is required for the very first use of the Mamba 25
or whenever used with a new/different transmitter.
The Mamba 25 contains a throttle calibration feature that you’ll want to use the first time you
power it up with a new/different transmitter. Performing this exercise will teach the
controller how your transmitter works.
