The programming instructions are terrible almost impossible to understand. I want to setup for heli with 5 second delay and also soft start. Also what are the default settings from the factory?

Anyone have any success in programming this thing using the transmitter? I followed the instructions in the manual to turn the brake on, and it seems to be working (i.e., cycles through the tones for each setting and gives the confirmation tone when the throttle is lowered as described in the manual) but does not return to operational mode after the confirmation tone. If I cycle the power to the ESC it works again, but all settings are default (no brake). I have two of these and they both behave the same, so it must be an issue with the programming procedure. Any ideas?

I have the same problem! Can anyone help?

Ok I found the problem. On the first set of 4 beeps return throttle to 0% to calibrate the ESC so it knows what 0% is! Then try the brake. If it still does not work, go back into program mode and on the second set of 4 beeps move the throttle stick to zero to enable the brake! took me hours to figure this out! But I am a noob!
