Hi,

I just built a T-rex 450S. Everything installed well and looks fine except the ESC. Once I connect the battery to the ESC it keep 'beep..beep...beep..........' (non-stop) till I disconnect the battery. Anyone knows what's happened and how to fix it? Thanks.


A short video for reference:

Hey Tema,

Mine did the same thing. I eventually figured out that if the ESC isn't connected to the motor it just beeps. I can't tell in the video if the motor is connected. It was really hard for me to trust the throttle stick at high position for programing in the instructions....but it works and make sure your throttle curve is linear (0-25-50-75-100)during set up or the ESC will set wrong. Then you can set your curve after the ESC has been programed....FYI.

Also, I'm told the connectors you are using (look like the tamiya style) are way bad for lipo power. Overheat/arch/melt....I'm using deans...Don't want to sound pushy..just what i have been told.

Hope I helped.


NOTE*** I just noticed that if the throttle stick is not in all the way down it will beep (a failsafe so the motor doesn't start accidently).
