e sky speed control

when i first put in my upgraded speed control it worked great. when i would throttle up it would go didi didi didi didi and di di di at low end. but since sunday this has changed at the low end to a didi diudi didi tone can any one help me figure this out or is this ok to fly. i did fly it and no problems but i dont want to crash.

you can always try setting the throttle end points again, with the heli and Tx off, move the throttle to full stick, then plug the heli in but keep your hand above the main blades in case it starts to spin up, it should NOT spin up but at least if it does you can catch it before getting hurt, then turn the Tx on and wait for the beeping to stop, then move the throttle stick to the lowest position, I usually unplug the heli wait a few and then plug it back in with the Tx on first and throttle at the lowest position.

well i tried all the steps that you gave me and i still get the same result with the didi didi didi at the bottom ( no di di di ) , could this be a low volt thing
